Plated Half-Holes Castellated Holes

Plated half holes(castellated holes)are holes that made off the edge of the boards plated with

copper using a specialized process. It is predominantly used for board-on-board connections, mostly where two printed circuit boards with different technologies are combined.

Through connecting the PCBs together directly, the whole system is considerably thinner than a comparable connection with multi-pin connectors. The plated edges are also useful in producing mini PCB modules. 

Plated half holes are available in both standard PCB and advanced PCB. For standard PCB service, the minimum diameter of castellated holes is 0.6 mm. If you need smaller castellated holes  please ask our sale to offer advanced PCB service.  And the minimum distance between two Plated half holes is 0.55 mm.

So how to manufacture the Plated half holes? The plating is protected from mechanical damaging by setting back the copper shell. Therefore the plated half-holes can be milled precisely and improve the process reliability strongly
