I'm trying to get data off of this IC, and I'm having trouble finding a suitable package. In addition, I need to test ~5 of these on the same PCB, so I need to use a socket.
The problem is, I need HUNDREDS of pins. (The previous engineer designed a chip with 626 --yes, 626-- pins, which I've gotta deal with). Now I only really need to connect roughly 250 or so of these to test. We tried a PGA package, but it didn't work for a number of reasons.
So I've found a great looking TQFP socket:
And a pretty great looking QFP package:
My only question is, would they work together? They have the same 0.5 mm pitch, and the sizings seem to match. From what I can tell, the only difference is the height of the package itself. We don't even need to close the clamshell of the TQFP socket in our tests, so a taller package shouldn't hurt us.
Any help would be so greatly appreciated! Or if you have other ideas/locations to get a matching package/socket, lemme hear them!
