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.
