Solder Reflow Recommendations

Notes:

•

MF-USMF models cannot be wave soldered.

•

If reflow temperatures exceed the recommended profile,

devices may not meet the performance requirements.

•

Compatible with Pb and Pb-free solder reflow profiles.

•

Excess solder may cause a short circuit, especially during hand

Recommendation guidelines.
