Thank you to all. We have a BGA package that we suspect for Pop corning or delaminating that we need to have scanned. As usual, Tech-Net comes thru with sound advice and help. My hat is off to the Net. You too Duane......

They will happily sell you one, or if you just need some small jobs done they do work on analysis by contract. They will provide a full report with analysis, pretty thorough - and color pictures to impress the boss. Good equipment to look for die delamination within a chip, and we've used them to check for voiding in underfill materials. We also used them to check for package delamination on some ICs where we had to re-form the leads a bit... I believe they have offices in California and in near Chicago. http://www.sonoscan.com/ regards, Graham Collins Process Engineer, Northrop Grumman Canada Corporation Halifax (902) 873-2000 ext 6215 >>> [log in to unmask] 07/30/03 03:33PM >>> I have just had a discussion with a fellow associate, and he is on the hunt for somebody able to do something called SAM (Scanning Acoustic Microscope.) Anyone heard of any such animal.
