I've seen clamp/pallets that are spring loaded to make solid contact with
the pads and balls.

Best of luck,

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
