Solder reflow
Recommended reflow methods: IR, vapor phase oven, hot air oven.
Devices are not designed to be wave soldered to the bottom side of the
board.
Gluing the devices is not recommended.
Recommended maximum paste thickness is 0.25 mm (.010 inch).
Devices can be cleaned using standard industry methods and solvents.
Note:
If reflow temperatures exceed the recommended profile, devices may not
meet the performance requirements.
Rework
A device should not be reworked.
