    Plated half holes are mainly used for board-on-board connections, mostly where two printed circuit boards with different technologies are combined. E.g. the combination of complex microcontroler modules with common, individually designed PCBs.

    Additional applications are display, HF or ceramic modules which are soldered to the base printed circuit board.

    The board-on-board PCBs therefore need plated half holes, which serve as SMD connection pads. Through directly connecting the PCBs together, the whole system is considerably thinner than a comparable connection with multi-pin connectors.


    • The milling tolerance is +/- 150µm
    • The milling gap within a panel needs to be 10mm min.


    Through setting back the copper shell from the conture, the plating is protected from mechanical damaging.
    Therefore the  plated half-holes can be milled precisely what strongly improves the process reliability.
