I am trying to make an order for my first board, but here is the issue. I have two designs which I would like to put on a single board to keep costs down. They have exactly the same width, but different length. I am trying to establish what is the best way to lay them out so that I have the easiest time separating it later and without adding extra costs. My understanding is because they are not of exactly the same size than I can't ask for them to be properly panelized for free. For now I have laid them out width to width with an overall outline and a separation line on a silk screen layer and just a few small holes to act as a guide when I cut them later (so that I have good registration on both sides). But how many holes can I put in before extra charges kick in? And generally what is the maximum thing that can be done in this case to make separation as easy as possible afterwards, but without incurring significant costs? Thanks, Kostic
