Hi, I think your friend wrongly changed the D code so that the finger width doesn't meet your requirements. And the fingers have long and short ones, which is hard to do selective gold plating because of not easy to add plating wires. Of course, you

1. To protect the nickel and copper under gold plating from oxidization before soldering. Gold plating can extend the PCB self-life and improve the solderability for 2nd re-flow. 2. Provide a good bonding strength. For Chip on Board process that Gol

Dave: It's good to know what that stuff is. With your NiO, you have the typical ENIG problem. I can imagine some causes for your disaster: * too thin gold plating * oxidized nickel under gold plating * porous nickel plating * wrong soldering pr
