We have a very serious dewetting problem with at least one supplier. We have seen as much as 80% with the HASL down to 10 microinches. The area of dewetting can not be reflowed, we have tried. problem is from copper/tin intermettalics, poor cleaning after applying solder mask, contamination, etc. get a good FA lab like NEXTEK and have them run on a X-Ray floroscope. ############################################################## TechNet Mail List provided as a free service by IPC using LISTSERV 1.8c ############################################################## To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TECHNET <your full name> To unsubscribe: SIGNOFF TECHNET ############################################################## Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information.
