    Metal Dome Arrays which may incorporate a large number of domes in a pattern to carter different custom application

    Working principle : The snap dome is located at the conductive part on the PCB (most of which is above the gold finger on the PCB). When pressed, the central dimple of the

    dome is concave and contacts the circuit on the PCB , Thus, the circuit is formed, and the current passes through, and the whole product can work successfully .

    Fix the Metal dome by adhesive PET Film. In accordance with customer s requirement ,from products' structure, it can divided into : Single -layer ,Double-Layer, UV,Silver printing,Membrane Panel and etc

    Metal Dome Array is mainly sorted by :
    A. (Yellow):High-temperature resist material , proceed SMT in the short time .
    B. (Transparent) : Convenient to position alignment
    C. (White) :normally used for Light-guide-film, reflection function
    D. (Silver Printing):Grounding anti-static effect .
    E. (Black) :normally used for light-block

    Remove polyester with adhesive and paste it on the PCB board. Then press it lightly and it will stick firmly on the board.
