Startling Results From Reliability Testing
Since the EU�s Restriction of Hazardous Substances (RoHS) Directive � adopted in 2003 � banned lead in electronics products intended for the EU�s internal market, the transition to a lead-free soldering process has been far from problem-free. But that reliability would turn out to be such a big issue has been a surprise to most in the industry. Credit / Source: Lars Wallin

Lead Free Tacking Part 1 (4 min. 36 sec.) Best, Inc 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.

Open product reliability testing in Stockholm, Sweden in January as part of a live production event generated some quite startling results. It was apparent that many components simply cannot handle the high reflow temperatures of a lead-free soldering process, and that many surface-mount machine suppliers are battling significant problems with QFN packages and other components that are mounting edgeways (bill boarding). However, some suppliers have achieved good results.
