I have a pcb design on which I would like to have a small text logo, not in silkscreen, but in actual copper with a tin layer. So that the text looks like an smd solder pad. From looking on the internet I have discovered how I can expose the copper of my text by copying it on the top soldermask layer. But I do not know how to have my text tinned like in smd pads. How do I have my exposed copper tinned?
