Anyone doubting the reality of the conversion to lead free soldering (as many seem to do) may wish to look at this page. Also of good value for anyone involved in the change. This is the page for the 10th International Conference on Lead Free Electronic Components and Assemblies to be held in October this year. Co sponsors are IPC=97Association Connecting Electronics Industries and JEDEC=97the Solid State Technology Association. While there is no detailed technical information here, what is of great value is the paper titles and the fairly extensive lists of "what you will learn". Between them these provide a good (& disturbing) idea of the problems and challenges of lead free soldering. http://www.pb-free.org/ RM --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
