hi,

some years ago, for prototyping a design, we designed adapter boards that interfaced qfp's to pga patterns.  the qfp's were soldered to the adapter board which also had pins soldered to it.  this assembly was then plugged into sockets on a wirewrap board.  they were pretty simple, inexpensive designs.

if you have trouble finding the exact combination of pga pattern to w/w board pattern, this would be the way to go.

phil

Hey all!

I am currently working on my Senior Design project for my EE degree.

Without going into too many of the details, I was wondering if anyone can answer the following question:

Does a socket-type device exist that will convert an QFP to a PGA?

We are working on a custom VXI interface for BFGoodrich and our sponsor engineer wants us to look for PGAs so that we can build a prototype on a wire wranp board and avoid having a PCB built (at least in this stage of the game).

Thanks!
