    Metal Dome Arrays

    Metal Dome Array & Metal Dome Sheets

    The (metal dome array)is the most cost effective solution for a simple switch with a superior tactile interface between your equipment and the user. A metal dome array & sheet (dome array) is a kind of PET sheet that carries metal dome contacts. It is applied to PCBs to function as switches of mobile phones and electric home appliances. Compared to the membrane polyester switch which was formerly used, it gives good click-feeling. It also gives much longer lasting life span compared to poly dome sheets. It also takes place of down going productivity of tact switches with its potential productivity.

    It is possible to manufacture metal dome arrays with various size and weight to meet customers' request. And of course it's possible to be developed into various types followed by customers' requests. At present, we make the following basic types of dome arrays.

    This type is used in the early period of metal dome arrays (dome arrays) industry. Metal dome contacts are attached under Maylar (one layer of adhesive PET film). On the sheet, there is an air hole for each dome contact and it is essential for good click-feeling.
    This type is somehow similar to single layer type by means of metal dome contacts attached under Maylar. But the difference is that, in this type, the Spacer is attached under the metal dome contacts. Air paths which function like air holes in single-layer, helps provide good click-feeling when dome contacts are pressed. Besides this effect, air paths help reduce the chance for PET film being damaged by metal dome contacts' burr and block dust coming into PET films.
    On top of the Mayler which carries metal dome contacts, silver paste or silver carbon paste is printed as ESD (Electrostatic Discharge Control). This helps reduce electrostatic which might be harmful to other parts inside of mobile phones. Electrostatic is gathered on the printed silver paste or silver carbon paste and neutralized.
    - EMI Single layer
    EMI is printed on top of single-layer metal dome arrays (dome arrays).
    - EMI Double layer
    EMI is printed on top of double-layer metal dome arrays (dome arrays)
    There's one layer of Rubber Glue on top of the Mayler or EMI. It has special Plastic performance and can be tightly stick on Keypad or PCBs.
