What is Metal Dome Array ?
A metal dome array & sheet (dome array) is a kind of glued PET array & sheet that carries metal dome, which will be peeled easy from the released paper and place sticky on circuit boards, as a switche of electronic device.  So it also need "peel & place metal dome", in viewing of metal dome packing.  You can put single dome or several metal dome per array, as per designed purposed, mostly the same quantity and location as PAD of circuit board which will be sticked on.

Usage of Metal Dome Array:
Metal dome contacts on the arrays (sheets) are positioned over the contact point of PCBs. When a dome is pressed, the center of it contacts to the PCB and let the electric current flow through. This is how metal dome arrays work. Please click our blog to see how to assemble metal dome array on PCB.

Advantage of Metal Dome Array:
The dome array (metal dome array)is the most cost effective solution for a simple switch with a superior tactile interface between your equipment and the user.  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. Becuase metal dome used.
