I work for a PCB Manufacture and I am looking for info on BGA Pull test or strenght test. I have a CM that is experiencing bga's with some weak joints. they are telling me that when they do their pull test the joints are breaking at the nickel inste

I was wondering if anyone could direct me towards documentation on shear test methods/apparatus to test the bond integrity of a solder ball to its substrate. Thanks.

I am currently involved in a reliability project related to SMT QFP and TSSOP fine pitch solder joint reliability. I have decided to use a temp chamber for stress testing. Is there a test standard that covers this? I am also a bit unsre as to whether

Dear Sir, Sorry for the delay in reply. This is regarding MIL standard for bond pull strength: MIL-STD-883C dt.25/08/83 Bond strength (destructive bond pull test); refer table-1 Minimum bond strengths for various wire composition & diameter given.

Well, I can't speak for them falling off later on, as that's not when I see them, and they are passing their wire pull tests after bonding. What I am seeing is electrical opens during testing, and these opens coincide with the Au/Al bonded points. Th
