Just you just stick matching pads on the bottom of the board and have the whole mess reflow soldered or did you cut through plated holes at the edges or something like that?

Pics in abse. Our QC lady had the idea of routing halfway through the pth's, which worked great. This was a retrofit to about a hundred boards in the field. Maxim sampled us 3200 of the 9691 chips, to replace the failing 9690's.

Nice. I guess I think like your QC lady. ;-)
