I need to add a slot to a PC board to allow an otherwise unused connector to stick through an overlay PC board I’m creating. Is there anything I need to do at the board level to ensure the slot is milled out? The cutout is already included on the Edge Cuts layer…
I uploaded the Gerbers to one PC board house and used their Gerber viewer. All the layer files had checkmarks except Edge Cuts, which had a ! by it and no explanation.
If this was JLCPCB: their check mechanism is unreliable and random at times. I’ve had many a board made there and all of them were ok. All of them had exclamation marks, prominently on edge.cuts.
If something is really wrong with a board, they contact you via eMail. And they are good at it. I once forgot a USB connector’s positioning stud holes. They found that.
