What are the key process requirements to achieve reliable lead-free SMT assembly?
Lead-free SMT can be achieved reliably if several process requirements are implemented carefully. Some of the variables to account for are listed below. The most common alloys used in lead-free SMT are tin-silver-copper alloys; these alloys all have a meting range between 217-220�C. These alloys all melt at higher temperatures than traditional leaded solders such as the 63/37which has a melting point of 183�C.

BEST Instructors have put to video demonstrations of common hand soldering skills. These are not designed to be in place of live one on one training where repetitive skills and subsequent one on one feedback is given. Rather they are quick refreshers designed to be viewed if a specific skill has not been practiced in a while.
