Are you sure it was Texas Instruments PN# TMS320C6201GJC200? It's got a heavy metal heat sink on top of it...and it is quite heavy. I've placed a lot of other T.I. BGA's as well and never had any problems. I've got a digital picture of the "squished" balls if you would like to see it. The paste print was good and not smudged at all...I don't know if I have any bridging or not because I can't see with the xray I have. Wonder what you're doing different than I or Rick Thompson are doing? Rick stated that he had bridging problems until he started shimming the part...if we're talking about the same part that is... -Steve Gregory- ############################################################## 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.
