The question about PCB Fabrication

1834 1 Feb 23.2020, 00:10:47

I've now designed my very first PC board, and am in the process of reviewing it. One thing that occurred to me is that I created a couple of custom pads and wasn't paying attention to whether the hole sizes were standard drill sizes. It's no problem to go back and change them, but my question, is: Is there a set of standard drill sizes that should be used?V-score is so the boards can snap apart?
