2. Devices can be cleaned using standard
methods and aqueous solvent.
3. Rework use standard industry practices.
4. Storage Envorinment : < 30℃ / 60%RH
Caution:
1. If reflow temperatures exceed the
recommended profile, devices may not meet
the performance requirements.
2. Devices are not designed to be wave soldered
to the bottom side of the board.
