Solder reflow



Due to “Lead Free” nature, Temperature

and Dwell time for the soldering zone is

higher than those for Non-compliant parts.

This may cause damage to other

components.



Recommended max solder paste thickness

> 0.25mm.



Devices can be cleaned using standard

methods and aqueous solvent.



Rework should utilize standard industry

practices. These changes should apply to

all notes for each case size.



Storage Environment : < 30ºC / 60%RH

Caution:



If reflow temperatures exceed the

recommended profile, devices may not

meet the performance requirements.



Devices are not designed to be wave

soldered to the bottom side of the board.
