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 recom-
mended.
• 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.
