I have outlined this process before, but I thought a little repetition wouldn't hurt. PGC is the most common gold plating salt. It is used in both acid gold baths (pH usually about 4.3 - 6.0) and cyanide gold baths (pH of usually 10.3 or higher). Most all gold plating on electronics is done in acid baths containing PGC, which also often contain ...

It isn't 11% nickel. It's only what the XRF sees of the surface. X-rays can only penetrate a small distance from the surface so it sees the gold on top the strongest, the thicker nickel layer is shielded partly by the gold so even if there is more nickel than gold (usually by a factor of 5-10) it reports less of that.
