EMI ESSENTIALS 

**EMI INTRODUCTION** 

## **Overview of EMC/RFI Issues** 

The phenomenon of electromagnetic interference (EMI) is familiar to virtually everyone, even if they do not understand the underlying principles. Most people have witnessed firsthand the effects of interference. To control EMI, government organizations, such as the FCC, CSA, and EEC, mandate that manufacturers may not design, produce or sell electronic equipment that jams the public broadcast services. In other instances, however, EMI can constitute more than a mere nuisance. The military and medical communities, for example, require trouble-free operation of their electronic equipment in adverse electromagnetic environments since malfunctions could jeopardize missions and personnel.  The European Union’s EMC directive also mandates that “the apparatus has an adequate level of intrinsic immunity to electromagnetic disturbance to enable it to operate as intended”. 

## **EMC Design of High Speed Systems** 

The interference and susceptibility (immunity) effects of electronic apparatus are created by time-variant electromagnetic fields which may be propagated along a conducting medium or by radiation through space. Because the source of the conducted and radiated interference energy levels may be related, a coordinated systems design effort is required to reduce these effects. 

A design program for an equipment item that must meet both an emission and an immunity requirement consists of: 

- Suppression: Reducing the interference at its source. 

- Isolation: Isolating the offending circuits by filtering, grounding and shielding. 

- Desensitization: Increasing the immunity of any susceptible circuits. 

These three steps should be carried on throughout the entire equipment design and implemented as early as possible within the design program. 

## **Effects of Logic Speed** 

The trend in today’s electronic devices is faster, smaller, and digital rather than analog. Most equipment (95%) of today contains digital circuits. Today’s digital designer must create a circuit board that has the lowest possible EMI, combined with the highest possible operating/processing speeds. Design of the PCB is the most critical EMC influencing factor for any system, since virtually all active devices are located on the board. It is the changing current (accelerated electron movement) produced by the active devices that result in EMI. 

## **Design Approaches** 

There are two approaches that can be used to reduce the emission from the PC board. The first approach is to operate the circuit at the slowest speeds consistent with the functionality of the system, lay out the PCB with the smallest possible loop areas (especially the high speed devices), and insert suppression components such as filters, ferrite beads, and bypass capacitors into the circuit to reduce its bandwidth. These techniques will result in a desired decrease in the high frequency harmonic amplitudes and circuit bandwidth and a corresponding undesired decrease in both the operating speed and system reliability. The use of slower speeds with reduced bandwidth will help to desensitize the circuit to external susceptibility fields. 

The second is to use shielding. Shielding is the only non-invasive suppression technique. Since the shielding is not inserted into the circuit, it does not affect the high frequency operating speed of the system, nor does it affect the operation of the system should changes be made to the design in the future. In addition, shielding does not create timing problems and waveform distortion; it does not decrease system reliability; and it reduces crosstalk. Plus, shielding works for both emission suppression as well as susceptibility (immunity) problems. 

Even with the overall advantages of shielding, the most cost-effective approach is to use a combination of circuit suppression/hardening and shielding.

## **BOARD LEVEL SHIELDS** EZ PEEL[™] 

## **PATENTED SHIELDS ARE SCORED TO ALLOW PEEL-OFF WHEN ACCESS IS NEEDED** 

These patented shields have a solid top, scored to allow peel-off when access to board level components within the shield is required. 

The peel-off feature prevents damage to the board and components by eliminating the need for labor intensive de-soldering, which can often result in increased scrap. Peeling off the cover is accomplished by using a small starter hole for simple removal. This hand operation requires minimal force using a hook scriber or tweezers. 

After repair, replacement or adjustment of internal components, the shield can be resealed using a replacement cover. Laird offers two replacement cover options: a snap-in cover and a dish cover. 

The snap-in cover utilizes a lance and hole design. The replacement cover snaps into place and locks into a lance feature on the frame of the original shield. 

The other option is a dish cover that gets soldered into place on the board. The dish shape allows for self-location of the cover for soldering. 

EZ Peel board level shields can be packaged in tape and reel formats for easy SMT installation using conventional pick-and-place equipment. The four standard sizes are also available without the EZ Peel (scored) feature. 

## **Features and Benefits:** 

- Easy removal of scored cover area 

- Only requires 1.5 lbs force for cover removal 

- Simple replacement technique for cover 

- Use on surface mount or through-hole applications 

- Shield retains all physical properties after PCMCIA/JEIDA testing for shock, bending, torque, drop and vibration 

- CRS 1008/1010 (tin plated) for solderability 

## RIGID CORNER 

The rigid corner board-level shield incorporates a corner design that optimizes component rigidity for increased part and printed circuit board (PCB) firmness. As PCB designers are increasingly using thinner substrates, a rigid frame reinforces the assembly, thereby improving overall ruggedness and performance. The shield has improved solder joint reliability and resistance to solder joint fracture, especially in drop testing performance with thin PCBs. Several standard Laird EMI style parts including single-piece, two-piece, and multi-compartmental board-level shields use this new rigid corner design, along with availability in custom sizes as well. 

The rigid corner shield is stronger and more robust than traditional formed shields, which results in coplanarity improvement of the solder castellations. The shield can tolerate more deflection (i.e., more handling) without plastic deformation. Elimination of drawn flange reduces the space needed on the PCB for shielding trace width by potentially ~0.3 mm, allowing for the shield to be more closely placed on the PCB. Elimination of draft allows for more undershield space and improved component clearance. 

The partially drawn corner is located near the top portion the shield, resulting in improved torsional rigidity with no drawn lip and no draft. For parts over 2 mm, the corner is both drawn and formed with an interlocking multi-radius corner, which provides superior EMI shielding effectiveness. The interlocking corner can be meshed and closed in during the forming and drawing process for additional improved rigidity for parts taller than 2 mm. For parts under 2 mm, the entire corner is drawn without an interlocking corner. 

## FEATURES 

- Corner openings are reduced, improving shielding performance 

- Partially drawn corner located near the top portion of the corner combined with 90° straight forming of wall sections for improved torsional rigidity. 

- U.S. Patent No. 7,488,902

EMI ESSENTIALS 

## **BOARD LEVEL SHIELDS** 

## **INTRODUCTION** 

The complexities of today's electronics pose several design challenges. Resolving EMI needs to be balanced with space, weight and production restraints. When designing a custom shielding solution, beginning in the earliest stages of the application design allows  effective elimination of EMI while meeting all specifications. 

Laird board level shielding experts work through all phases of development. From design, rapid prototyping and pre-production through production and automated packaging, Laird has the experience to help speed a product to market and stay within budget. 

To increase manufacturing throughout and reduce costs, Laird has developed a proprietary in-line production process that includes part formation, wash, assembly, inspection and automated packaging. 

By integrating quality processes, board level shield quality and performance is ensured from design stage through final packaging. One process is the automated co-planarity inspection system. Laird replicates the customer application by measuring shields in the same plane as the printed circuit board. This is accomplished without "securing" or "touching" shields, which could throw off measurement and/or deform parts. Laird measures shields immediately prior to placement into carrier tape at speeds that match automation packing. Shield base materials include our exclusive Shield-Lite[TM] , CRS 1008/1010, beryllium copper alloys, nickel-silver alloys, copper-based alloys and spring steels. All shields are fully solderable. 

## **ONE-PIECE SHIELD DESIGN** 

## **LOW COST/EXCELLENT EFFECTIVENESS** 

Custom surface mount shields are available in both one-piece and two-piece designs. One-piece shields provide six sides of protection, with the sixth side being the board itself. One-piece designs offer economical shielding alternatives where access to covered components for repair is not necessary. 

## **TWO-PIECE SHIELD DESIGN QUICK, EASY REPAIR AND INSPECTION OF COVERED COMPONENTS** 

Two-piece board level shields offer users the flexibility to inspect or repair shielded components without having to risk board damage by removing the entire shield. Covers snap on and off with ease, making repairs quicker and easier, and reducing board re-work. Two-piece shields are available pre-assembled or unassembled. Large locking dimples snap into slots on covers to provide mechanical retention force. Smaller grounding dimples provide electrical grounding for proper shielding and to prevent rattle. Two-piece shields survive drop, shock and no-rattle tests. Here are critical test results: 

- Able to withstand acceleration of 4g from 10 Hz to 2000 Hz for three hours in each of three planes as per SAE J1455 

- Pass EN 50 155 for railway electrical equipment including vibration test 

- of 30g from 5 Hz to 200 Hz in 3 directions and a shock test with 500 m/s for 11/ms 

- Pass standard telecommunications drop tests [6 faces, dropped 1 meter 

- onto concrete floor]

Series 97-2100<br>**----- End of picture text -----**<br>


## **MULTI-COMPARTMENTAL SHIELD DESIGN** 

## **SHIELD MULTIPLE CIRCUIT GROUPS SAVE PCB SPACE AND PRODUCTION TIME** 

Multi-compartmental shields feature internal dividing walls of one material thickness and meet all on-board shield requirements for FCC, VDE, CISPR and CE. These shields are available in two-piece designs, either assembled or unassembled. Our unassembled versions allow for automatic optical inspection prior to cover placement. As in all our shielding offerings, Laird proprietary process for 100% automatic optical inspection verifies co-planarity including inner walls. 

## **DRAWN BOARD LEVEL SHIELDS** 

## **SEAMLESS CORNERS ADDRESS HIGH-FREQUENCY LEAKAGE** 

As microprocessor speeds continue to increase, so does the potential for EMI leakage through the smallest apertures in board level shields. Laird drawn board level shields are designed to provide additional near-field and far-field circuit isolation (attenuation) at higher frequencies by eliminating the apertures found in the corners of traditional board level solutions. Drawn board level shields utilize small ground trace sizes, thereby preserving space on the circuit board. 

- Solid corner designs when additional circuit isolation (attenuation) is required at higher frequencies 

- Available in custom heights up to .250" (6,4 mm) with length and width dimensions from .300" (7,6 mm)  to 2.0" (50,8 mm) 

- Tape and reel packaging provides an economical and automated SMT attachment method 

- Available in cold rolled steel, brass, stainless steel and nickel silver 

- Molded Compartment Shields and Form-In-Place elastomers can be combined with drawn board level shields to achieve shielding of multiple components with a single part 

- Available with an EZ Peel scored cover feature; allows for easy top section removal for component repair and re-sealing 

- Ventilation holes as needed for solder outgassing.

To identify proper mounting track, select width and corresponding part number from the above chart. Replace the “X” with required material thickness. 

Laird shielding devices may be mounted quickly and easily using any of several different oe methods. Each installation method is described in the text that follows. However, if you should run into a unique situation not resolved by any of these methods, give us a call. More than likely we can provide the exact answer you need. 

## 4. Allow 24 hours minimum curing time. 

## RIVET MOUNT 

Riveting produces a tight, long-lasting installation. Either plastic or metal rivets may be used. 

Standard parts are supplied with nonconductive tape. For rough surface applications, such as flame-sprayed surfaces, 0.010 in. (0.254 mm) thick nonconductive tape is recommended. Optional conductive tape is also available. Contact a sales department representative for additional ordering information. 

## SLOT MOUNT 

Slot mounted parts are easily installed using slots where bi-directional movement is required. Simply install part into one slot and snap it into the second slot or over the edge of the frame. 

## CLIP-ON MOUNTING 

## ADHESIVE MOUNTING 

Clip-on gaskets hold firmly in place due to their own spring characteristics. Simply push the strips onto the edge or flange of the door or enclosure. Also available are clip-on gaskets with either “T” or “D” lances. 

Sticky Fingers[®] is an instant, pressure-sensitive adhesive bonding system, ideal for all-purpose contact strips for metal cabinets and electronic enclosures, and is unaffected by temperatures from -67 to +250°F (-55 to +121°C). 

## TAPE TRACK MOUNTING 

Simply follow these four easy steps: 

Stainless Steel mounting track with PSA (pressure sensitive adhesive) is available on the Symmetrical Slotted Series and Slot Mount Series. 

1. Remove all grease and oily residue with solvent. Smooth the mounting surface with emery cloth. 

## 2. Peel off protective paper backing. 

## WELDING 

3. Place gasket in correct position. (See mounting methods diagrams A through E.) Press firmly to ensure a good adhesive bond. Avoid repositioning, which might impair the effectiveness of the adhesive or may bend or kink the strip. 

Welded mounting requires simple, traditional welding techniques. 

## SOLDERING 

Solder mounting requires normal low temperature soldering techniques, including cleaning and fluxing of parts with common copper flux materials. 

NOTE: On items where fingers cover the solid portion of the gasket, pressure may be applied 16 by inserting a mandrel in the strip and pressing down. For contact strips with Magnefil[®] insert, simply press down on the fingers.

Laird introduces Variable Slot Mount shielding, which eliminates the use of long slots while still utilizing the easy installation method of slot mount shielding. Fingers are removed from the strip in areas where a mounting slot is not present. The Variable Slot Mount shielding strips can be customized to any patterned series of slots. 

- Easy and cost-effective installation since fasteners and adhesives are not required 

- Improved shielding effectiveness compared to traditional slot mount series through elimination of long slots in host material 

- Slot mounting feature can be varied to accommodate different lengths and hole mounting patterns (see figure 2) 

- Three and five pitch segments ideal for grounding applications 

- Bi-directional wiping and compression action to accommodate a wide variety of designs 

- Available in standard (77-Series) and UltraSoft[®] (78-Series low compression versions) 

- Ability to retrofit equipment when higher clock speeds limit current slot mount product without changing slot size or location 

- One piece construction eliminates handling individual pieces, thereby shortening installation time 

- Ideal for grounding and shielding in the following electronic enclosure applications: 

- Front panel handles – Chassis covers – Backplanes – Plug-in units – Subrack assemblies

These versatile gaskets are made from highperformance beryllium copper with Sticky Fingers[®] self-adhesive backing. They provide an extremely tight, instant bond and are ideal as an all-purpose contact strip for metal cabinets and electronic enclosures, particularly where space is critical. 

Magnetic field shielding effectiveness of these strips has been proven to be > 46 dB for a 14 kHz plane wave and 108 dB for a 10 GHz plane wave. When tested per MIL-STD-285 for electromagnetic shielding, these strips showed superior performance under minimum compression. They proved to be especially effective where variations exist in the space to be shielded and in applications that require high shielding performance despite frequent opening and closing of the cabinet. 

Strips 97-500 and 97-538 are furnished in standard lengths of 24.000 in. (609.600 mm) and in continuous 25.0 ft. (7.6 m) coils. Series 97-520 and 97-540 are supplied in standard 16.000 in. (406.400 mm) lengths and in 25.0 ft. (7.6 m) coils. Strips 97-537, 97-535 and 97-545 are supplied in 12.000 in. (304.800 mm) lengths. All are available in your choice of finishes, see page 17. 

Please note that designated strips are available with Magnefil[®] , a rubber strip filled with magnetic absorbing particles and inserted within the curve of the fingers. Magnefil provides increased magnetic field shielding. 

These 97-Series products are also available in UltraSoft[®] low compression force 98-Series.

This series from Laird is designed for use where high temperature or other design considerations preclude the use of adhesive-mounted gasketing. Yet it provides the same shielding characteristics and effectiveness as on Sticky Fingers[®] mounted series. Clip-On Gaskets offer shielding effectiveness >100 dB for 100 MHz plane wave. All are available in your choice of finishes, see page 17. These 97-Series products are also available in UltraSoft[®] low compression force 98-Series. 

SNAP-TITE[®] WITH “D” LANCE 

This configuration has been designed specifically to provide outstanding holding power. “D” lances snap into drilled or punched holes in the mounting surface to create a strong omnidirectional grip with excellent conductivity. 

MINI CLIP-ON Laird Mini Clip-On (97-645/646) Gaskets are designed for use on today’s thinner, lighter materials. 

- Lowest compression force available in clip-on configuration 

- Virtually no compression set – 100% recovery of original height at up to 60% compression 

- “D” lance for extra holding power 

- Optimum conductivity and mechanical properties of beryllium copper 

- High cycle life – 50,000 cycles without fracture, wear, or compression set

## GBIC FIBER OPTIC SHIELD 

Laird offers the GBIC Shield for reducing emissions from GBIC (GigaBit Interface Converter) fiber optic transceivers. Fiber optic transceivers can be a troublesome source of EMI because they emit high-frequency signals and are located adjacent to large apertures in the enclosure. The GBIC Fiber Optic Shield assembly reduces the radiated emissions from the transceivers by conducting interference current away from the transceiver and onto the enclosure surface. 

Simple assembly of the shield is accomplished by snapping the two shield halves onto an uninstalled guide rail assembly. The rail is then mounted onto the printed circuit board in the normal fashion.

Spring finger design on both halves of the GBIC shield provide grounding for both sides of a transceiver module. In addition, the bottom half fingers can provide a low impedance connection to the circuit board ground plane. 

- Fits most Tyco (AMP) and Methode guide rails common to routers, switches and other network hardware 

- Requires no extra mounting holes or solder 

- Provided in stainless steel for high galvanic compatibility 

- Simple snap-on assembly

## **CUSTOM PRECISION ELECTRONIC CONTACTS** 

## **GAIN MAXIMUM ELECTRICAL AND CARRYING PERFORMANCE** 

From concept to placement, Laird has the expertise to deliver custom precision surface mount contacts. Using the latest computer simulation techniques, Laird provides properly designed contacts that ground, carry current and signals, and interconnect boards and devices. Laird uses basic geometric parameters (length, width, uncompressed height, compressed height, contact force) to conduct Finite Element Analysis (FEA) on your prospective design. With the FEA results, we can then identify the best design to optimize a product's operational performance. Features are incorporated to provide for placement and soldering of the contact onto the circuit board. 

Laird offers a wide range of plating options to allow for maximum electrical current carrying performance. 

**^**[Automated packaging allows for complex and small designs with lower ] installed costs. 

Contact base materials include beryllium copper, phosphor bronze, nickel and stainless steel. All contacts are fully solderable as required.

## **METALS GALVANIC COMPATIBILITY CHART** 

For harsh environments (presence of fair to good ionic conductors), all metals in contact with each other should be no more than one level of the chart apart to minimize corrosion. This is shown by the dark blue regions of the plating bar chart under specific platings. Outdoor applications, high humidity and salt air fall into this category. 

For normal environments (storage in warehouses or non-temperature/humidity-controlled environments, etc.), the difference between dissimilar metals should not exceed 0.25 volts (5 chart levels counting the origin). This is shown by thelight blue regions of the chart under specific platings. 

For office environments (temperature and humidity controlled), 0.5 volts can be tolerated(10 chart levels counting the origin). This is shown by the dark gray regions under specific platings. Caution should be maintained when deciding that your application is temperature and humidity controlled. Many devices intended for use in office environments are storedin warehouses for extended periods of time before and in between use. 

These are general guidelines which apply under most circumstances, but corrosion is a very complex subject whose details could not possibly fit in this space. If you are not sure which metals are compatible, please feel free to contact Laird and talk to our corrosion experts.

This catalog is designed to provide helpful information to engineers on our expanded product line.  In this section, you will find benefits for Fabric-Over-Foam gaskets, material options and an extensive list of profile and I/O sizes and configurations. 

Laird specializes in quick turnaround of custom shapes and sizes of EMI shielding gaskets.  If you don’t find exactly what you need, our engineers will help you design the right solution to your shielding problem. 

A sampling for standard profiles are shown; custom configurations and sizes can be designed to meet your specific requirements. Profiles are shown in ascending order by height (starting on page 58). 

The recommended operating compression for Fabric-Over-Foam EMI Gaskets will vary depending on the shape and size of the particular gasket. 

Typically, D-Shaped, Rectangular Shaped, and Square Shaped Fabric-Over-Foam EMI Gaskets should be compressed between 30% and 50% of the foam height. 

Similarly, C-Shaped Fabric-Over-Foam EMI Gaskets should typically be compressed between 50% and 75% of the gasket height. 

Force Displacement Resistance (FDR) graphs are available upon request. Please contact engineering department at Laird when unsure. 

Certain combinations of materials may not be available for all Profiles or I/Os. Please consult the Engineering Department at Laird when unsure.

The following pages show examples of standard I/O gaskets used in computer and telecommunication applications. If you have different requirements, the Engineering Department will design gaskets to the specifications you supply. Laird will design your I/O from a fully detailed print, drawing file, or the actual panel to which the gasket is to be applied. 

|**I/O GASKET TOLERANCES**|**I/O GASKET TOLERANCES**|
|---|---|
|Height tolerance|± .020" (±0.5 mm)|
|Width tolerance|± .020" (±0.5 mm)|

## **BASIC I/O GASKET DESIGN** 

**1.** Space between required cutouts should match or exceed 0.060" (1,5 mm). 

**2.** Distance from the edge of a cutout should be at least 0.060" (1,5 mm) from the edge of the gasket. In most cases, a slot can be used in place of a hole that is positioned too close to the gasket edge. 

**3.** All cutouts and locations are designed customer specifications. 

**4.** Pressure Sensitive Adhesive (PSA) and Extended Release Liner (ERL) can be applied in parallel with the long edge of the gasket. 

The recommended operating compression for Fabric-Over-Foam EMI gaskets will vary depending on the shape and size of the particular gasket. Typically, I/O gaskets should be compressed between 30% and 50% of the foam height.

EMI ESSENTIALS 

## **KNITTED CONDUCTIVE GASKETS** ELECTROMESH[®] TAPE 

Laird ElectroMesh tape has a double layered strip of knitted wire mesh to provide effective EMI shielding and grounding for electrical and electronic cable assemblies. 

It is particularly useful in applications where the need for EMI protection is determined after cable assembly is complete and standard braided cable jackets cannot be used. The flexible structure of the ElectroMesh Tape permits it to conform to irregular surfaces and contours during the wrapping process. 

- Tin plating for excellent solderability 

- Useful in both shielding and grounding applications forstatic discharge 

- Tin plated copper clad steel wire provides greater strength and performance than other tape materials 

- Knit loop structure provides uniform coverage without any wrinkles or creases 

- Available in other alloys and wire dimensions 

- Supplied in 50 ft. (15,2 m) rolls. (Note: When determining quantity needed, 50% overlap is recommended.)

EMI ESSENTIALS 

## **METAL IMPREGNATED** MATERIALS 

## **ELECTROMET™ ORIENTED WIRE** 

ElectroMet oriented wire gaskets are EMI shielding and sealing composites. Monel[®] or aluminum wires embedded in the elastomer and oriented perpendicular to the mating surfaces provide the EMI sealing. Solid or sponge silicone provides the weather sealing; however, solid silicone weather seals are recommended for high-pressure applications. 

Silicone based oriented wire composites are capable of withstanding temperature ranges from –70°F to 500°F (–56°C to 260°C). Oriented wire materials are available in sheet or strip form with a minimum thickness of 0.032 in. (0,8 mm). Material specifications and information for standard sheets and strips are provided in Tables 1 through 3.

EMI ESSENTIALS 

## **AUTOMATED FORM-IN-PLACE** EMI GASKET TECHNOLOGIES 

## **INTRODUCTION** 

Laird form-in-place is an automated system for dispensing conductive elastomer EMI shielding and grounding gaskets onto metal or plastic substrates. Form-in-place is particularly well suited for cellular phones, PDAs, PC cards, telecom base stations, radios, and many other compartmentalized cast or plastic enclosures and packaged electronic assemblies. 

Utilizing programmable 3-axis CNC dispensing equipment, the compound is dispensed accurately onto the substrate and creates a secure bond during the curing process. The repeatable computer-controlled dispensing pattern insures consistency between parts and rapid part program changes. In addition, it supports all levels of volume – from prototyping to high-volume electronic component production – via the use of one or multiple dispensing heads. The system is programmed to apply custom gasket configurations onto parts, to form multiple levels on the part, and on slopes up to approximately 70°. 

Laird RXP compounds are Room Temperature Vulcanizing (RTV) elastomers and HXP compounds are High Temperature Vulcanizing (HTV) elastomers, both filled with proprietary conductive particles. Dispensed gasket beads of RXP compounds may be handled in 3 hours, and are cured in 24 hours, under conditions of standard temperature and 50% Relative Humidity. Dispensed gasket beads of HXP compounds can be handled after the materials are cured in an oven. The compounds have a working compression range from 10% to 50% of the gasket height, with a recommended design compression of 30% against a mechanical compression stop. Our product is designed to support low closure forces and is compatible with plastic, metal, and plated or chromate finished substrates. 

**Automated dispensing of compound is controlled by sophisticated computer software, which is user-friendly and easy to work with.** 

## **FORM-IN-PLACE GASKETING FEATURES AND BENEFITS** 

- Form-in-place gasketing offers a total cost savings in the form of reduced raw materials, labor or assembly time 

- Room temperature cure gasketing materials eliminate the need for costly heat curing systems, allowing the use of inexpensive plastic or metal substrates 

- Single-component compounds eliminate the need for mixing ingredients, thereby shortening production cycles and eliminating related waste 

- Easy to program operating system allows for quick part-topart change-over, minimal tooling investment for new designs, and prototype development in 24 to 48 hours 

- High shielding effectiveness: 85–100 dB up to 10 GHz 

The required force to compress a given bead is a function of the compound and the gasket size; i.e. smaller gaskets require less force than larger gaskets. Please refer to our technical data for details. Gaskets are dispensed on substrates within a placement tolerance of ± 0.001 inches and gasket cross-sectional tolerances from ± 0.003 to 0.007 inches. Refer to Table 1 on page 104 for typical gasket dimensions and tolerances. As a normal course of equipment operations, starting points and termination ends of the gaskets will have profiles that are approximately 25% larger than the running gaskets. 

- The dispensing system supports prototyping and high volume production schedules in a space saving 4’ x 3’ [12 sq. ft.] (1,2 m x 0,9 m [1,1 sq. m]) footprint 

- Form-in-place gaskets provide more critical packaging space for board level components and smaller package dimensions 

- Excellent adhesion on a wide variety of metal and plastic substrates including: 

- aluminum and other casting alloys 

- stainless steel 

- nickel copper plating (on plastics) 

## **TYPICAL APPLICATION FOR FORM-IN-PLACE GASKETS:** 

- copper, silver, and nickel filled paint (on plastics) 

- Low compression force makes SN compounds an excellent selection where the mating surfaces lack mechanical stiffness

EMI ESSENTIALS 

## **DESIGN GUIDE** FOR COMMERCIAL MICROWAVE ABSORBERS 

Microwave absorbers have been used in military applications for several decades. They have been traditionally used for EMI reduction, antenna pattern shaping and radar cross reduction. More recently with the rise of wireless electronics and the movement to higher frequencies microwave absorbers or “noise suppression sheets” (NSS) are used to reduce electromagnetic interference (EMI) inside of the wireless electronics assemblies. 

Two types of NSS are used for these types of applications. They are described below: 

## **MAGNETIC ABSORBERS** 

## **ABSORBER APPLICATIONS** 

Electronic operating at high frequencies can have problems with emission of high frequency noise. Once put inside an enclosure, the energy will add in phase at certain frequencies to cause resonances which will hinder the performance of the device. A good example of this phenomenon is seen in Figure 1. The amplifier was measured in the condition shown and subsequently remeasured inside of its enclosure. When put inside the enclosure the performance was severely degraded due to cavity resonances inside of the enclosure. The measured data is shown below in Figure 2. 

These are thin (.1 to 3 mm) polymeric materials filled with magnetic particles. These materials have both high permeability (magnetic loss properties) and high permittivity (dielectric loss properties). This combination of properties makes these materials very effective in eliminating high frequency EMI 

Laird has two product types that are used for commercial applications: 

- Q-Zorb HP (high permeability) uses novel magnetic fillers to achieve extremely high permeabilities at low frequencies. This allows for relatively thin materials to provide EMI reduction at frequencies below 2 GHz. This material comes in thicknesses of .15 mm and .5 mm. 

- Q-Zorb HF (high frequency) is the optimum choice for cavity resonance problems from 2-18 GHz and higher. The material is available in thicknesses from .5 mm to 3.2 mm and is supplied in sheets or as die cut components. Both materials are UL-VO and ROHS compliant. They can be supplied with pressure sensitive adhesive (PSA) for ease of installation. 

## **FOAM ABSORBERS** 

These absorbers are based upon open celled foam impregnated with a carbon coating. The carbon coating makes the resultant product lossy at microwave frequencies, indeed acting like a free space resistor to incoming electromagnetic energy. These foam products range from 3.2 mm to 6.4 mm for internal cavity applications and can be several centimeters thick for outdoor applications. Two main product types are offered by Laird 

- RFLS- Lossy sheets are uniformly loaded with the carbon coating and used at 3.2 mm and 6.4 mm thick. They are supplied as sheet materials and may have PSA applied and fire retardant coatings.

- RFRET- is a reticulated foam based absorber. The materials are thicker ranging from 3/8” to 2” in thickness. They can be used for air filtration and EMI, or on the inside of cabinet doors for broadband EMI attenuation.

EMI ESSENTIALS 

## **DESIGN GUIDE** FOR COMMERCIAL MICROWAVE ABSORBERS 

To improve the performance of the device, Laird Q-Zorb microwave absorber was put on the inside cover of the enclosure. This is a standard way in which absorbers are used. Q-Zorb is supplied with a pressure sensitive adhesive to allow for ease of installation. The cover is shown below in Figure 3. 

## **MAGNETIC ABSORBER VS. LOSSY FOAM** 

In these enclosure applications the designer needs to understand the tradeoffs between using the magnetic absorber vs the lossy foam type absorber. The foam absorber is a much more cost effective solution, provided it will meet the performance goals. However there are a couple major reasons to use the magnetic sheet absorbers (Q-Zorb) 

- Foam absorbers can breakdown over time causing resistive particles to drop onto to circuit traces 

- Energy along the side walls of cavity are H field (magnetic) dominated currents. The E field is at a minimum along the walls and materials with only dielectric loss (resistive foams) will not perform very well in these applications. The magnetic absorbers have high H field loss and attenuate these currents. 

Figures 5 and 6 below do show the use of a lossy foam absorber inside of an amplifier cavity.

## **DESIGN GUIDE** FOR COMMERCIAL MICROWAVE ABSORBERS 

## **TUNED FREQUENCY VS SURFACE WAVE ABSORBERS** 

Laird offers two types of Q-Zorb materials: tuned frequency and surface wave absorbers. Tuned frequency materials are used in far field applications such as direct radar reflections off of an object. Surface wave absorbers are used for high angle of incidence applications and for cavity noise suppression. Many design engineers that have a cavity noise problem at a certain frequency want to use a tuned frequency absorber tuned to that frequency. However that is not the best performance they can achieve. Note that the tuned frequency materials offer good performance at normal angles of incidence, but perform more

poorly at higher angles of incidence. Inside the cavity noise generated is at a number of angles of incidence and also a significant of surface wave energy. The surface wave materials offer better performance in these applications. The curves below compare a tuned frequency absorber at normal incidence and at all angles of incidence. Note the improved bandwidth of the surface wave loading especially at higher angles of incidence. The Q-Zorb samples in the Laird Absorber sample kit are the surface wave absorber type. They are the best solution for solving cavity noise problems.

## **EMI MODELING** 

Laird is a member of the EMC Consortium at Missouri Science and Technology School, Rolla Missouri. As part of this consortium Laird is modeling the use of absorbers for a variety of applications. The cavity application discussed above is one of the key areas of investigation. Other areas include directly placing absorbers on noisy chips, coating cables to reduce conducted EMI, and use on antennas. Laird is working on modeling these applications using 3D modeling software including HFSS, Microwave Studio, and EZ-FTDT. The Q-Zorb can be modeled as a Debye Oscillator and directly input into the codes. Laird can supply these models to customers for their own computer modeling. A few examples of this work are shown in the figures below. 

Figure 7. Microwave CST Model of Cable with Q-Zorb Coating 

## **SAMPLE KIT** 

To assist the microwave design engineer in the use of Laird absorbers, a sample kit containing the different types of microwave absorbers is offered. The kit contains all three types of materials including Q-Zorb HF, Q-Zorb HP, and RF Foam. A description of the sample kit is listed below. 

The samples are 6”x 4” in size and can be easily cut into specific shaped pads. There are various thicknesses to evaluate. Generally speaking the thicker the sample the better it will work at low frequency. However if you are constrained by thickness, evaluate the one that will meet the thickness requirements and then test the electrical properties of the sample. To make even thicker test samples the samples can be bonded together. This will allow the designer to evaluate thickness vs performance.

FIGURE 1.<br>**----- End of picture text -----**<br>


Increasing use of printed circuit boards in complex electronics requires unique shielding solutions. Laird has developed a near field measurement to accurately determine the effectiveness of board-level shielding. Several Laird board-level shields have been characterized using this technique. 

Laird has further enhanced performance at greater than 2 GHz by adding a microwave absorber to the board-level shield. Further work has been completed on Flomerics[TM] FLO-EMC to analytically investigate board-level shields performance improvement using absorbers at high frequency. 

## **THERMALLY CONDUCTIVE ABSORBERS – COOL-ZORB** 

VBROP can optimize absorber performance at various frequencies and angles of incidence. 

Laird is developing thermally conductive microwave absorbing materials. These can be used as thermal pads between chips and heatsinks, allowing conduction of heat and dissipation of EMI. Initial testing and modeling has shown this to be an effective solution to heat sink radiation from noisy chips. 

## **MU EPSILON MEASUREMENT CAPABILITIES** 

Laird has a network analyzer to make amplitude and phase measurements from 130 MHz to 20 GHz. Laird also has a reflectivity arch, transmission tunnel and a variety of coaxial, wave-guide and other test equipment to determine intrinsic electrical properties of absorber materials. This ability has enabled Laird to build a database that customers can use to design new absorbers and analyze their performance in different situations. 

Absorber Board-level Shield (ABLS) 

## **ANALYTICAL SOFTWARE VBROP** 

VBROP is a versatile Windows[®] 95/98/NT-based optimizer of multi-layered stacks for reflection or maximum transmission at specified frequencies, angle of incidence and polarization. The visual basic front-end makes the software extremely user friendly, with interactive analysis of layer properties versus performance. It is useful for the design, optimization and detailed performance analysis of RAM, RAS, radomes and microwave windows.
