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.
