77-010 Beryllium Copper Spring - A Solution to EMI Issues [E密斯]

It's widely known that electromagnetic radiation poses significant harm to human health. Prolonged exposure to electromagnetic radiation pollution can lead to symptoms such as fatigue, decreased memory, and reduced physiological functions. Therefore, people are increasingly concerned about electromagnetic radiation. Solving EMI issues requires not only good design but also the critical use of EMI materials.

Most common shielding bodies are made of metal structures, such as computer cases and cabinets. In addition to the metal shell, there are display windows, ventilation openings, cable interfaces, button panels, and more. Fully enclosed metal cases do not have issues with excessive radiation, as materials like aluminum alloy and stainless steel offer very high shielding effectiveness. Radiation problems often arise from areas such as display windows, ventilation openings, cables, and gaps in the case.

For drawer-style cases, there is a gap between the side frames of the drawer and the case, which are highly susceptible to electromagnetic leakage. The tightness of the contact between the side frames and the case is a crucial indicator of the excellence of electromagnetic compatibility (EMC). In response to this EMI issue, Yimisi offers a solution: EMS-77-010.Beryllium copper spring strip

The EMS-77-010 is a槽安装铍铜簧片, each section is identical, suitable for various slot installation applications. This product can be used for grounding and EMI shielding. The EMS-77-010 metal spring sheet features the following characteristics:

The cost of groove processing is low.

2. No glue or fasteners required; easy installation.

3. Features bidirectional sliding compression with wide applicability.

4. Suitable for grounding and shielding designs for front panels, drawer units, cabinet covers, PCB cards, etc.

Compared to other standard EMI spring sheets, the EMS-77-010 metal spring sheet offers superior elasticity, allowing for a tighter fit between the side frames and the case. It not only resolves the issue of other pads not being able to withstand shearing forces but also boasts low compression pressure, a narrow deformation range, excellent shielding performance in both low and high frequency ranges. Additionally, it features high thermal conductivity, lightweight, and is unaffected by nuclear explosions, ultraviolet radiation, and ozone, effectively addressing the issue of electromagnetic radiation leakage.
