Adhesive-backed metal electromagnetic shielding covers are precision structural components manufactured using sheet metal stamping and adhesive backing processes. They are available in materials such as nickel silver, brass, phosphor bronze, and stainless steel, and can undergo surface treatments such as tin plating, nickel plating, gold plating, passivation, and adhesive backing. Common names include adhesive-backed RF shielding covers, PCB shielding reinforcement boards, adhesive-backed metal shielding components, and communication equipment shielding covers. They are primarily used in consumer electronics, communication equipment, automotive electronics, and medical device industries, and are suitable for high-frequency circuit shielding on PCBs, protection of mobile phone/tablet signal modules, electromagnetic isolation of automotive electronic components, anti-interference of precision modules in medical equipment, and RF module shielding in communication equipment. They effectively achieve electromagnetic isolation and anti-interference functions.
