Pick and PlaceNozzle

MSL Rating

Lead-free Reflow Profile

The 1A Open Frame modules use an open frame construction and aredesigned for a fully automated assembly process. We suggest the pick andplace operations is inductor.

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

Storage and Handling

The recommended storage environment and handling procedures formoisture-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 3or 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 conditionsof ≦ 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 amaximum of 12 months from the bag seal date, when stored at the following
conditions: < 40° C, < 90% relative humidity.

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

Power Systems will comply with J-STD-020 (Moisture/Reflow Sensitivity
Classification for non-hermetic Solid State Surface Mount Devices) for bothPb-free solder profiles and MSL classification procedures. This standard
provides a recommended forced-air-convection reflow profile based on thevolume and thickness of the package. The suggested Pb-free solder paste isSn/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.

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 don not generate asmuch gases when the flux reduce the metal oxides or react withcontaminants during the soldering process.
