Half-hole board is a successful application on circuit boards. Its appearance solves many functional requirements that cannot be achieved by ordinary boards. It has great market demand and promotion value. PCB half-holes are rows of holes drilled along the boundary of PCB. When the holes are copper-plated, the edges are trimmed to halve the holes along the boundary, making the edge of the PCB look like there is copper in the holes on the electroplated surface.
