![]() ![]() a cleaner way is to simply draw a square pad top and bottom and connect it vertically. ![]() And the edge of the board will not have vertical plating either. The problem is this creates burrs and may rip the metallisation off the hole wall. The sloppy way is to simply specify a large via or pad and mill it in half. This requires tight tolerances on the countour milling. At the end of the production run the isolation fingers are milled off. After that pcb follows classic electroplating so copper grows only on the contact area that was left after milling. Then the board is milled again to remove the copper deposits where no copper should be. Then the board is subjected to a selective plating using electroless copper to create the edge contacts. Essentially the castellation contact area is milled first together with the drill holes in the board. it requires additional steps in the pcb process that they don't have. Batchpcb or iteadstudio cannot handle this. ![]() Altium will never give your email address to any third party.Indeed boards with castellated contacts.
