ENVIRONMENTAL ISSUES IN ELECTRONICS AND THE TRANSITION TO LEAD-FREE SOLDERINGAuthor: Kay Nimmo

This legislation, together with similar action in other regions will also place more emphasis on recycling end-of-life goods and therefore easier disassembly processes.
Although interest in lead-free soldering has fluctuated over the past 10 years, the recent activity in both the EC and Japan, where lead-free solder is starting to be used in mass production, has again highlighted the importance of this subject. Similarly, halide-free products are also starting to appear in Japan.
This paper describes environmental legislation and market forces world-wide that will impact on the electronics industry, and, will also summarize a recent analysis of the status of lead-free soldering. The main conclusion from this work was that lead-free soldering is technologically possible, but key implementation issues need to be addressed. Short descriptions of alternatives to halogenated flame retardants are also be included.
