SUGGESTED STRESS RELIEF METHODS
1. Make sure that the devices are mounted on flat surfaces
(.001" under the device) to optimize the heat transfer.
2. Position device on mounting surface and solder in place
using an indalloy type or a 60/40 type solder.
3. Solder leads in place using a 60/40 type solder with a
controlled temperature iron (700F).
