Environmentally friendly is a term rapidly invading the electronics industry.

The electronic industry will be facing great challenges over the next few years as the solder used in electronic products is migrating toward lead-free. This is being driven by mandates in Europe such as Waste Electrical and Electronic Equipment (WEEE) and Restrictions of Hazardous Substances (RoHS) and similar ones in Japan. There also is a great deal of pressure in the US to do the same.

How many times have your customers returned products or circuit boards with reported defects that you can’t find? Every manufacturer experiences this situation at some time. Your customer reports a problem in your product and sends it back to you. You test the faulty product in your lab and the problem doesn’t occur. Sometimes you try to bend it or tap it against the table. You may even try heating it in a chamber or with a heat gun or using a freeze spray. Still the problem does not expose itself.
