Both processes can be performed with Pb-containing or Pb-free solders. The termination options available for these soldering techniques are AgPd and Barrier Type End Terminations. |**End Termination**|**Designation**|**Recommended and Suitable for**|**RoHS Compliant**| |---|---|---|---| |Ag/Pd|PV Series…R1|Pb-containingsoldering|Yes| |Barrier Type End Termination|PV Series…N R1|Pb-containingand Pb-free soldering|Yes| |NiSn End Termination|PV Series ...Ni R1|Pb-containingand Pb-free soldering|Yes| ## **Wave Soldering** This process is generally associated with discrete components mounted on the underside of printed circuit boards, or for large top-side components with bottom-side mounting tabs to be attached, such as the frames of transformers, relays, connectors, etc. SMD varistors to be wave soldered are first glued to the circuit board, usually with an epoxy adhesive. When all components on the PCB have been positioned and an appropriate amount of time is allowed for adhesive curing, the completed assembly is then placed on a conveyor and run through a single, double wave process. ## **Infrared Reflow Soldering** These reflow processes are typically associated with top-side component placement. This technique utilizes a mixture of adhesive and solder compounds (and sometimes fluxes) that are blended into a paste. The paste is then screened onto PCB soldering pads specifically designed to accept a particular sized SMD component. The recommended solder paste wet layer thickness is 100 to 300 µm. Once the circuit board is fully populated with SMD components, it is placed in a reflow environment, where the paste is heated to slightly above its eutectic temperature. When the solder paste reflows, the SMD components are attached to the solder pads. ## **Solder Fluxes** Solder fluxes are generally applied to populated circuit boards to keep oxides from forming during the heating process and to facilitate the flowing of the solder. Solder fluxes can be either a part of the solder paste compound or separate materials, usually fluids. Recommended fluxes are: - non-activated (R) fluxes, whenever possible - mildly activated (RMA) fluxes of class L3CN - class ORLO Activated (RA), water soluble or strong acidic fluxes with a chlorine content > 0.2 wt. % are NOT RECOMMENDED. The use of such fluxes could create high leakage current paths along the body of the varistor components. When a flux is applied prior to wave soldering, it is important to completely dry any residual flux solvents prior to the soldering process. ## **Thermal Shock** To avoid the possibility of generating stresses in the varistor chip due to thermal shock, a preheat stage to within 100 °C of the peak soldering process temperature is recommended. Additionally, SMD varistors should not be subjected to a temperature gradient greater than 4 °C/sec., with an ideal gradient being 2 °C/sec. Peak temperatures should be controlled. Wave and Reflow soldering conditions for SMD varistors with Pb-containing solders are shown on the next page in Fig. 1 and 2 respectively, while Wave and Reflow soldering conditions for SMD varistors with Pb-free solders are shown in Fig. 1 and 3. Whenever several different types of SMD components are being soldered, each having a specific soldering profile, the soldering profile with the least heat and the minimum amount of heating time is recommended. Once soldering has been completed, it is necessary to minimize the possibility of thermal shock by allowing the hot PCB to cool to less than 50 °C before cleaning.

Test results and accompanying samples are retained for a minimum of two (2) years. The solderability of a specific lot can be checked at any time within this period, should a customer require this information. ## **Rework Criteria - Soldering Iron** Unless absolutely necessary, the use of soldering irons is NOT recommended for reworking varistors encapsulated in plastic. If no other means of rework is available, the following criteria must be strictly followed: • Do not allow the tip of the iron to directly contact the top of the plastic • Do not exceed the following soldering iron specifications: Output Power .......................................30 Watts Maximum Temperature of Soldering Iron Tip .......280 °C Maximum Soldering Time .....................................10 Seconds Maximum ## **Storage Conditions** SMD varistors should be used within 1 year of purchase to avoid possible soldering problems caused by oxidized terminals. The storage environment should be controlled, with humidity less than 40 % and temperature between -25 and +45 °C. Varistor chips should always be stored in their original packaged unit. Specifications are subject to change without notice. Users should verify actual device performance in their specific applications.

Users should always verify the actual performance of the Bourns[®] product in their specific devices and applications, and make their own independent judgments regarding the amount of additional test margin to design into their device or application to compensate for differences between laboratory and real world conditions. Unless Bourns has explicitly designated an individual Bourns[®] product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949) or a particular qualification (e.g., UL listed or recognized), Bourns is not responsible for any failure of an individual Bourns[®] product to meet the requirements of such industry standard or particular qualification. Users of Bourns[®] products are responsible for ensuring compliance with safety-related requirements and standards applicable to their devices or applications. Bourns[®] products are not recommended, authorized or intended for use in nuclear, lifesaving, life-critical or life-sustaining applications, nor in any other applications where failure or malfunction may result in personal injury, death, or severe property or environmental damage. Unless expressly and specifically approved in writing by two authorized Bourns representatives on a case-by-case basis, use of any Bourns[®] products in such unauthorized applications might not be safe and thus is at the user’s sole risk. Life-critical applications include devices identified by the U.S. Food and Drug Administration as Class III devices and generally equivalent classifications outside of the United States. Bourns expressly identifies those Bourns[®] standard products that are suitable for use in automotive applications on such products’ data sheets in the section entitled “Applications.” Unless expressly and specifically approved in writing by two authorized Bourns representatives on a case-by-case basis, use of any other Bourns[®] standard products in an automotive application might not be safe and thus is not recommended, authorized or intended and is at the user’s sole risk. If Bourns expressly identifies a sub-category of automotive application in the data sheet for its standard products (such as infotainment or lighting), such identification means that Bourns has reviewed its standard product and has determined that if such Bourns[®] standard product is considered for potential use in automotive applications, it should only be used in such sub-category of automotive applications. Any reference to Bourns[®] standard product in the data sheet as compliant with the AEC-Q standard or “automotive grade” does not by itself mean that Bourns has approved such product for use in an automotive application. Bourns[®] standard products are not tested to comply with United States Federal Aviation Administration standards generally or any other generally equivalent governmental organization standard applicable to products designed or manufactured for use in aircraft or space applications. Bourns expressly identifies Bourns[®] standard products that are suitable for use in aircraft or space applications on such products’ data sheets in the section entitled “Applications.” Unless expressly and specifically approved in writing by two authorized Bourns representatives on a case-by-case basis, use of any other Bourns[®] standard product in an aircraft or space application might not be safe and thus is not recommended, authorized or intended and is at the user’s sole risk. The use and level of testing applicable to Bourns[®] custom products shall be negotiated on a case-by-case basis by Bourns and the user for which such Bourns[®] custom products are specially designed. Absent a written agreement between Bourns and the user regarding the use and level of such testing, the above provisions applicable to Bourns[®] standard products shall also apply to such Bourns[®] custom products. Users shall not sell, transfer, export or re-export any Bourns[®] products or technology for use in activities which involve the design, development, production, use or stockpiling of nuclear, chemical or biological weapons or missiles, nor shall they use Bourns[®] products or technology in any facility which engages in activities relating to such devices. The foregoing restrictions apply to all uses and applications that violate national or international prohibitions, including embargos or international regulations. Further, Bourns[®] products and Bourns technology and technical data may not under any circumstance be exported or re-exported to countries subject to international sanctions or embargoes. Bourns[®] products may not, without prior authorization from Bourns and/or the U.S. Government, be resold, transferred, or re-exported to any party not eligible to receive U.S. commodities, software, and technical data. To the maximum extent permitted by applicable law, Bourns disclaims (i) any and all liability for special, punitive, consequential, incidental or indirect damages or lost revenues or lost profits, and (ii) any and all implied warranties, including implied warranties of fitness for particular purpose, non-infringement and merchantability. _For your convenience, copies of this Legal Disclaimer Notice with German, Spanish, Japanese, Traditional Chinese and Simplified Chinese bilingual versions are available at:_ _Web Page: http://www.bourns.com/legal/disclaimers-terms-and-policies_ _PDF: http://www.bourns.com/docs/Legal/disclaimer.pdf_ C1753 05/17/18R
