I’m sorry, but these boards are a gimmick at best. I bought this double sided PCB expecting a double sided PCB. Instead, I got a board full of vias. This means that instead of being able to have a board that’s quick to prototype with and which allows for overlapping traces, you have a board that requires jumpers for overlapping traces and double the cutting (since you have to cut the traces on both sides).
I guess my question is this: what’s the point of making this double sided?
