Re: Layers of a pcb


So what actually exposes the copper are holes in the soldermask? Or both the holes in the soldermask and holes in the fill?

I’ll try to make the fill have holes in the shape of the pattern.
The route that I used was from Inkscape to a .png image, then to a Processing sketch I wrote to make tiny squares that would be on the pins and pads layer. Thought everything on that layer would then be exposed copper.
