So we are onto Soldermasking, protects the copper from corrosion, makes soldering easy, and it looks really good. Silk Screen is nice for assembly instructions and Board markings
The Process is virtually identical with Part 1 with some small differences:
Before you start the board has to be really clean, the discolored parts you see in the picture to the right is copper oxide and it makes the soldering process a nightmare. We use sandpaper just because it's easy to get, some people don't like it but I never had a problem. Just remember Remove all theoxide!
The important things to get perfect results are
Pretty nice eh?
