What are LMPA?


LMPA is short for Low Melting Point Alloys. These alloys allow you to use soldering temperatures that are considerably lower than for the traditional lead-free Sn(Ag)Cu (SAC) alloys.


LMPA-Q is an enhanced LMPA with superior mechanical properties. It's without exception the best alloy we have developed so far. The benefits are numerous.

What LMPA-Q will allow you to do

For all soldering processes

LMPA-Q can be used for all soldering processes:
