Dale: I have done some selective soldering and have had mixed success. CCAs with bottom side surface mount had to have been the toughest, however, the board itself was very dense and spacing was not conducive to selective soldering for that particular CCA, whereas others worked well. Spacing is key to allow solder flow. I had a lot of success with selective soldering flexes mounted to CCAs, connectors, and some PTH with bottom side SMT. Spacing is key. I called Eric Miller at Precision International, Ltd., and Eric was very helpful. Precision International has manufactured fixtures for selective soldering. Eric was able to send some guidelines which were very helpful. His number is 1-800-725-5388. *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * ***************************************************************************
