There are many companies who make emulation sockets for BGAs. Ironwood
Electronics, Gryphics, and E-tec are three that I have used extensively
and who specialize in this. They are all excellent choices for custom
socketing, but they have sockets available for most package sizes and
pin patterns in stock or can have them ready within a short time. Check
them out at:

Subject: [TN] temporary attachment of a BGA to a PCB for test

Fellow techs,



I have been asked to determine if there is a way to temporarily install
a BGA onto a test board using some type of conductive adhesive to make
electrical contact, electrical test and then safely remove the adhesive
without damaging the solder balls and be able to use the BGA.



Sounds impossible but I informed the design group I would check out the
options.



The other option we are looking at is to design a clamp/pallet that will
securely hold the BGA to the board.  The problem here may be making 100%
electrical contact on all 48 balls.



Anyone have any creative ideas they would like to share? Test sockets
are not an option.





thanks

Joe
