Plymouth, MA….The mechanical and electrical properties of beryllium copper make it the material of choice for EMI/RFI shielding products, as well as battery contacts, grounding clips, connector contacts, and ESD clips. Tech-Etch supplies many custom designed shielding components for special applications from high volume requirements using progressive dies, to prototype and small quantities utilizing photoetch fabrication. Beryllium Copper’s electrical properties provide shielding effectiveness over an extremely broad frequency range. At the same time, its mechanical properties yield a high deflection range, in addition to a long life without compression set. Bending tools capable of forming intricate sharp bends in tempers from annealed to full hard are produced in-house. Component parts are then inert atmosphere heat treated to enhance spring properties permitting greater deflection without compression set while achieving close dimensional control. Gaskets are finished in an expansive plating department where many finishes include tin, silver, zinc, sulfamate nickel, electroless nickel, palladium nickel and gold. A team of experienced product engineers is ready to answer any of your technical questions. A complete line of standard beryllium copper shielding gaskets is also offered with over 100 standard profiles.
