Stick-on Ploy Dome array

Poly Dome is use silver / carbon paste printed on a PET film and hot-pressed to form a convex hull to form a pressing function. To achieve the effect of pressing the PCB circuit board. Poly Dome can replace Metal Dome, the operation feel is better, the cost is low, and it can be compatible with various circuit boards.
