How to align a two layer PCB easy?
When I use Press-n-Peel for preparing a 2 layer DIY PCB. Aligning the bottom and top layer so that the holes and vias match on the copper between layers is a problem for me. To minimize the wrong alignment,can you have any advices for me?
When PCBs are produced in a factory,it used a chemical processto plate the holes. but when making PCBs at home you have to put a wire or component lead through and solder both sides.
