Solder reflow

Dwelling time for the soldering zone is higher

than those for Regular. This may cause

damage to other components.

1.

Recommended max past thickness > 0.25mm.

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.
