But we also have experience that regulations are introduced without taking into account all the consequences. We are seeing significant reliability problems with products using lead-free solder already. As a result, more and more classes of product are being exempted from the lead-free requirements of RoHS. It is IMPORTANT for manufacturers to keep aware of these changes before they introduce lead-free solder to their plant. >Using Sb in the tin? We haven't seen any indication of that. >Or is the tin pest just a theoretical problem? No, it certainly isn't. But, as I said in a previous post, it MAY not happen for some years, and then suddenly it does happen. >(Do you wonder why they bundled electronic recycling and lead free >together? It seems they expect short lifetime of electronics.) Not 'expect'; experience. Most office ITE is already scrapped after three years service. On the other hand, consumer electronics (TV sets) are kept typically for 10 years. -- OOO - Own Opinions Only.
