Vias can be one of the following types: Thru-Hole – this type of via passes from the Top layer to the Bottom layer and allows connections to all internal signal layers. It’s used in PCB modules which can be soldered to other PCB’s. Mounting - The placement/mounting style could be castellated along the edges, through-hole, or SMD. With a new script project established, add a new script to the project. That's not my experience at all. Spacing - Edge slot spacing should be in multiples of 0. Most commonly, they are used by designers to create PCB modules, such as Wi-Fi or Bluetooth modules, which will then be used as an independent part to be placed onto another board during the PCB assembly process. Space-saving: Castellated holes make the compact and space-saving design. Castellated beams are fabricated by using a computer operated cutting torch to cut a zigzag pattern along the web of a wide-flange section. As the holes pass through the plating, the edges are truncated, so the holes along the border will be halved. Close-up of the edge holes on a castellated PCB.
