Much to my horror, I discovered one of my 'standard' PCB footprints is 40% larger in both dimensions than the part it was intended for on my latest board. (It's a 16 pin device with pads on 0.5 mm centers)! The board is about 70% assembled and is much later than I would prefer. If I had unlimited time and money, I'd just spin the artwork with the correct footprint. Lacking either, I want to patch the existing board.
I've not located a prototype board that has the necessary footprint terminating in matching pads.
Here's what I'm thinking. I can upload a big bitmap of the correct footprint with exactly the right terminating pads to these guys and stamp a piece of my 0.005" PCB stock using say Epson Durabrite yellow ala:
Then I can stamp and etch as many adapter boards as I want. (I need one [1] adapter board.) Mount the device to the adapter then solder the terminating pads to the huge pads of the incorrect footprint.
What do you think of this idea?
