BGA Pull test

Electronics Forum | Mon Oct 25 17:50:46 EDT 2004 | Mike

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

solder ball shear test question

Electronics Forum | Fri May 17 16:37:28 EDT 2002 | Tom Druan

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.

temp stress reliability test for SMT solder bonds

Electronics Forum | Thu Apr 09 12:25:43 EDT 1998 | Dave Hammond

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

Plating for aluminum wire bonding

Electronics Forum | Tue May 13 21:08:24 EDT 2003 | ramanandkini

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.

temperature induced IMC in wire bonds?

Electronics Forum | Tue Nov 15 12:21:20 EST 2005 | arclightzero

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
