Edge Plating/Castellation

Edge Plating in PCB industry, sometimes referred to as Castellation or Sideplating, is a great way to ensure a strong connection through your printed circuit board and reduce the chance of board failures that can be costly to remedy. The surface finish of edge plating can be ENIG, ENEPIG, HASL and others if it can provide electrical connections. With sideplating, the printed circuit board (PCB) edge is used for technical features of the later PCB assembly.
