The advantages of screwing clampings

It is not easy to replace soldered finger-stocks in the doorframe of your test chamber. That's why we switched already in 1999 to screw clampings. Our colleague Gerco van Diemen explains why you will benefit from this. "Clampings hold the finger-stocks in place. Finger-stocks are the copper clamps that ensure that the door of a test chamber is completely sealed and no RF leakage occurs. They are a vulnerable part of a chamber's Faraday cage construction. Traditionally, these are soldered, but we have developed a way where using screws has the same protective effect."

Why would you want to replace the finger-stocks? Gerco: “Opening and closing the doors regularly makes them dirty, and dirt reduces the insulation performance. This is why we advise our customers to have the doors cleaned by us every two years. But sometimes, typically after >20 years of usage, the finger-stocks are worn out from heavy use and must be replaced before the shielding starts to suffer. Removing soldered finger stocks is very laborious, and we want to take our customers’ chambers out of production for maintenance as short as possible.”

Are you unsure if dirty or worn finger stocks are compromising the performance of your test chamber? If so, contact one of our technical consultants for advice. Hanneke Mertens – van Veen, Uliana Trucchi or Marc Le Roy will be happy to help.

Our services include maintenance and validated testing. We recommend that both are executed by authorized personnel only. Our expert teams can perform preventive maintenance on RF-shielded doors, mode-stirrer systems, and positioning equipment such as turntables. We also offer validation services to see if your EMC test chamber or RF-shielded room still functions within its intended limits and avoiding unexpected down-time or product recalls at the same time.

A shielded room can perform conducted emission and immunity EMC measurements, eliminating harmful external influences, leading to more accurate and consistent test results. Being a Faraday cage, a shielded room will not only improve test results but will also form an excellent aid in protecting information and essential hardware. Comtest can assist governments, the military, financial institutions, and large corporations in protecting what matters most in critical situations. We offer the highest quality, sensitivity, and security before, during and after working with you.
