Can anyone tell me where I can find land pattern design guidelines for BGA's with .65 mm pitch? IPC-SM-782 only has pad dimensions for BGA's of 1.0 mm and greater. I am placing a BGA which Hitachi calls its BP-240A package. The pad design on the boards seems too small, only .0098" while the ball size according to the spec is .0157". --------------------------------------------------- Technet Mail List provided as a free 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/html/forum.htm for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 -----------------------------------------------------
