Hi TN,

     Has anybody out there in the "real world" ever had cause to solder a
     BGA onto a socket so that it turns into a Pin Grid Array?  I need to
     make up some test boards for a customer, and we dont have the BGA at
     the minute, but the electrical folks want to test their design without
     waiting for the BGA to arrive.  Some body found a supplier who can
     supply an adaptor, which is essentially a piece of FR4 with enough
     pins to cover all the balls.  One end of each pin has a small cup to
     take the ball, while the other is a standard pin.

        It seems a simple enough idea, place the BGA and reflow,  has
     anybody done this before, or something similar?
        Do you think it likely that the I will need more solder paste in
     the cups?  Looking at the cup size, and the ball size I think I may
     have to add some paste, but the cups stick up nearly 2mm from the FR4,
     so printing is not really that suitable,  could dispensing be a better
     bet (dont have any experience in that!)

                Any help would be appreciated,

                        Thanks
                           Roger
