Look in the archives. If I remember correctly it is about 3.5 mg per sqmm. -----Original Message----- From: TechNet [mailto:[log in to unmask]]On Behalf Of David White Sent: Friday, June 07, 2002 1:57 PM To: [log in to unmask] Subject: [TN] BGA packaging? Technet, I am quoting on a new asm that has several BGA's (256 ball count and up) + a couple of very large 25mil fine pitch processors. We have never dealt with these before. The question is do I need to get a waffle pack changer for my Siemens Siplace line? Or can I order these parts on tape and reel. I assume the fine pitch will have to be in tray form, but what about the BGA's? What is the industry standard? Thanks David Ascom Energy Systems Inc.
