TWC provides large quantities of precision sheet metal as components for electromagnetic wave shielding and heat dissipation. In particular, the metal is used for PCB shield cases, shield covers, shim plates, and shield fingers made of beryllium-copper alloy for electronic device shielding and grounding. We provide custom-produced sheets of specific materials and shapes for communication base stations, IoT terminals, and other devices. We can also provide information on how to best mount the products in specific design models.
