Solder reflow
※ Due to “Lead Free” nature, Temperature and
Dwelling Time for the soldering zone is higher
than those for Regular. This may cause
damage to other components.
1. Recommended max paste thickness >
0.25mm.
2. Devices can be cleaned using standard
methods and aqueous solvent.
3. Rework use standard industry practices.
4. Storage Environment : < 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
