So, I'm obtaining a recently-made PC board, which was produced by some PC board house from Gerber files, the usual sort of small-run hobby project. This particular board, was with ENIG plating on board and fingers. This means, a micron-thick plating of gold over 150-200 microns of nickel, mostly for better soldering and copper protection. But that also "covers" the edge-connector fingers, they are not heavier gold. What's out there, for adding gold to those fingers? There's a good number of them, not just a dozen or two. I"m bothering to ask the question here, because it's a "vintage repair" problem also. A solution for one or two fingers, is a solution for many. Or, tell me "nickel isn't so bad, don't insert and remove it every day, you'll be fine". No, I won't spend $300, $600 for a gold-plating electro-pen system. If someone has that and wants to give me a quote, I'm all ears, tell me how many microns you'll plate. No, I won't mix up cyanide solutions, not likely to use nitric acid; it's outside my experiences and one "oops" could really ruin my day. I don't expect to rub gold-leaf on fingers and glue them down, that won't last. I may well go to some PC board shop and ask them for a quote, maybe someone has done that. So - what do people here know-of, from repair experiences or their own experiences? I have looked around the Web, there's means of doing these things, but it's hard to judge them "cold". And of course, it's hard to search on "hobbyist covering PCB edge connector with gold", there's many people selling products or showing how they mess with aqua regia or coat quarters with microns of gold.
