Note: All temperatures refer to of the package, measured on the package body surface.
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.
