Beryllium copper finger spring shielding pad

Material characteristics

The beryllium copper finger spring shielding pad is made of a special alloy beryllium copper, which has excellent electromagnetic compatibility shielding effect. Beryllium copper alloy spring has excellent compressive strength, resilience, corrosion resistance, and can provide good broadband electromagnetic shielding effect. At the same time, beryllium copper finger spring shielding pads also have the characteristics of high thermal conductivity, light weight, and are not affected by nuclear explosions, ultraviolet radiation, and ozone.

Structure and function

1. Structure:

   • The beryllium copper finger spring shielding pad adopts a finger spring design, which gives it good elasticity and deformability, and can adapt to gaps of different shapes and sizes.
   • The cross-section and shape of the pad can be customized according to customer needs to meet the requirements of various application scenarios.

2. Function:

   • Beryllium copper finger spring shielding pads can provide high shielding effectiveness over a wide frequency range for electronic devices, shielding rooms, microwave darkrooms, confidential conference rooms, doors, windows, and other locations that require frequent opening and closing.
   • In places where extreme pressure is required, various shapes and cross-sections of soft springs can also be provided to meet different shielding needs.

performance index

1. Shielding effectiveness: Beryllium copper finger spring shielding pads can achieve over 50dB in the frequency range of 100MHz~18GHz, demonstrating excellent shielding performance.
2. Deformation and rebound force: The pad has a large range of deformation and can quickly return to its original state after external force is removed, maintaining good shielding effect.

Application scope

Beryllium copper finger spring shielding pads are widely used in various occasions that require electromagnetic shielding, including but not limited to:

1. Communication equipment: such as mobile phones, wireless routers, communication base stations, etc., used to protect circuits, improve signal transmission quality and stability.
2. Electronic products, such as computers, televisions, speakers, etc., are used to reduce electromagnetic radiation and interference, protect internal circuits and devices.
3. Automotive electronics: such as car navigation, car audio, etc., used to shield interference signals from engines, electronic wiring harnesses, and other parts.
