Many firms sell membrane keypads and almost always talk about keypads which use conductive silver technology – but of course, the customer almost never learns about the disadvantages and risks of this kind of technology.

BOPLA, however, manufactures high-quality keypads with copper-laminated base membranes, galvanically silver-plated (gold-plated on request). The copper-laminated material is extremely flexible, so there is almost no possibility of breaks to the membrane cable, and problems such as silver migration are practically impossible.

Instead of using an adhesive as in the case of conductive silver technology, we can safely and permanently solder LEDs, photo diodes or other components, and these are features which give our customers the security they require for everyday use.
