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 past 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.
