6 Soldering Recommendations
QS9322 is compatible with industrial standard reflow profile for Pb-free solders. The reflow profile used is
dependent on the thermal mass of the entire populated PCB, heat transfer efficiency of the oven and
particular type of solder paste used. Consult the datasheet of particular solder paste for profile
configurations.. Since the profile used is process and layout dependent, the optimum profile should be
studied case by case. Thus following recommendation should be taken as a starting point guide.
- Refer to technical documentations of particular solder paste for profile configurations
- Avoid using more than one flow.
- Aperture size of the stencil should be 1:1 with the pad size.
