Technical Data 11182 Effective May 2021 

## **General information** 

## **Pick and place** 

The 1 A open frame modules use an open frame construction and are designed for a fully automated pick and place assembly process. 

## **MSL rating** 

The 1A Open frame modules have a MSL rating of 3. 

## **Storage and handling** 

## **Lead-free reflow profile** 

Power systems will comply with J-STD-020 (Moisture/reflow sensitivity classification for nonhermetic solid state surface mount devices) for both Pb-free solder profiles and MSL classification procedures. This standard provides a recommended forced-air-convection reflow profile based on the volume and thickness of the package. The suggested Pb-free solder paste is Sn/Ag/Cu (SAC). The recommended linear reflow profile using Sn/Ag/Cu solder is shown. Soldering outside of the recommended profile requires testing to verify results and performance. 

The recommended storage environment and handling procedures for moisture-sensitive surface mount packages is detailed in J-STD-033 (Handling, packing, shipping and use of moisture/reflow sensitive surface mount devices). 

Moisture barrier bags (MBB) with desiccant are required for MSL ratings of 3 or greater. These sealed packages should not be broken until time of use. Once the original package is broken, the floor life of the product at conditions of 30 °C and 60% relative humidity 168 hours varies according to the MSL rating (see J-STD-033). The shelf life for dry packed SMT packages will be a maximum of 12 months from the bag seal date, when stored at the following conditions: < 40 ° C, < 90% relative humidity. 

## **Post solder cleaning and drying considerations** 

To avoid contamination on the soldering pads extra care has to be taken when handling the boards. Clean soldering surfaces do not generate as many gases when the flux reduce the metal oxides or react with contaminants during the soldering process. 

## **Nozzle** 

The module weight has been kept to a minimum by using open frame construction. Variables such as nozzle size, tip style, vacuum pressure and placement speed should be considered to optimize this process.
