ahh i see now, no they are just traces tapped and some have been drilled so the wire can be put though to a tracer to avoid wire flapping around the button domes, TBH i didn't do this as i had my work mate (also a member of this forum) @banjokazooie did this for me because he had better solder equipment than i do, will dig to see if i have any more pics for yaFleder wrote:It looks like you drilled a hole and covered it with solder.
Like the pins/holes on the teensy, for example. Or were they already there on your PCB?
Since i did not have that holes in those places on my original board, i thought they were made by you.
