Hi, I'm not sure if this is the right place for this or not. I'm looking for guidelines for Castellated Mounting Holes, like in the picture. Are there any special considerations? This would be for JLCPCB fab house. Or should I email their tech support instead? ![edge.jpg](// Do they have to be gold plated or is HASL finishing ok? Many Thanks, rudi
