SUGGESTED STRESS RELIEF METHODS
SCALE:
NOT RECOMMENDED APPLICATION
SCALE:
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 an SN63 type solder.
3. Solder leads in place using an SN63 type solder with a
controlled temperature iron (210°C).
