Hi all:
I just had to 'repair' a 4" x 6" pcb due to an on the fly design change.:eek:

I had to add about 6 resistors, 3 ceramic caps, an 8 pin DIL socket and a 5 pin rotary encoder!
It had to fit in a specific oddball shaped space to interface with the other circuitry and the double sided original board had a ton of traces on the bottom layer.:banghead:

I used a dead bug component approach and custom designed a scissors cut PCB patch to work on the top ground layer.
Toner transfer, trim to size with scissors, offer up to orig. PCB...then etch and solder into place. Works a charm!:joyful:

Not particularly noticeable either.
 
Sure thing: Unpatched PCB, Patched PCB and dead bugs installed.:eek:
