Your design looks greatmunchausen wrote:vectorlight, how much did you have to shave off of the SOJ sockets to get them to fit? After quite a lot of wrangling, I've finished the design with the correct measurements, and by jove is it tight! I think each socket will need to slim down by at least a couple of mm to fit.
I filed off a bit from the left of the left-side socket and right of the right-side socket so they would butt-up against the header pins. On the IFEL board the socket contacts are not fully over the pads but enough to solder them on. Could you solder the chips straight on to the board that would take the socket size out of the equation?
