hi steve well all the guesses were blaming the board, dendrites, aligmnet, reisn starvation , but look at the chip in smoking 2 about half way up the crack on the chip you will see a black burn mark, the chip failed, not the board, as the chip cracked its usualy a sign it got real hot inside. seen it many times. if you pull the chip off i bet there is a burn mark under the chip where it got hot. well thats my guess anyway. robert Tarzwell ps they still dont get heavy copper do they i got three emails saying heavy copper is a dream and does not exist. --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 1.8e To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 -----------------------------------------------------
