    DPC technology (Direct Plated Copper)

    DPC technology (Direct Plated Copper)


    Stapes of the technological process:


    1. Formation of a thin continuous film of conductive material on a ceramic substrate. In this case, there may be holes in the substrate;


    2. Applying a photoresist to the formed conductive layer;


    3. Exposure and manifestation of photoresist;


    4. Galvanic build-up of copper metallization of the required thickness;


    5. Application of Ni-Au finish coating;


    6. Removing the photoresist from the surface of the board;


    7. Chemical etching of the conductive layer remaining on the ceramic after removing the photoresist.

    An equally important characteristic that determines the durability of products is the resistance of the metallized board to temperature effects. Thermal cycling testing was carried out according to MIL-STD-202.107G. This method is designed to determine the stability of a ceramic substrate with metallization to a cyclic temperature change.

    Test conditions:


    • -400C (30 min)~1250 oC (30 min), 500 cycles;
    • adhesion measurement method: bursting machine;
    • conditions: adhesion ≥ 3 kg.
