Solder-free assembly - A more environmentally friendly alternative to lead-free

摘要

The electronics industry has used solder as a means of connecting components to PCBs since near the time of its inception. Solder has been a faithful partner in that role up until the EU's recent mandate that electronic solder be made lead-free. This new era marks the transition of solder from faithful servant of the electronics assembly to technological nemesis. Pick up nearly any manufacturing journal today and you are likely to encounter more than one article citing the problems or challenges of lead-free, or proposing a new solution or investigative tool to better unearth the problems of lead-free.
