Handa Shielding TCS Dual-Wing Wire Mesh: Advanced Electromagnetic Shielding Solution

Handa Shielding TCS Dual-Wing Wire Mesh

Handa Shielding’s TCS Dual-Wing Wire Mesh is a cutting-edge electromagnetic interference (EMI) and radio frequency interference (RFI) shielding product designed to meet the rigorous demands of modern electronic systems. Combining innovative materials science with precision engineering, this mesh offers superior performance in critical applications such as telecommunications, aerospace, medical devices, and industrial electronics. Below is a detailed overview of its features, technical specifications, and applications.

Core Technology: TCS Material Innovation

The TCS in TCS Dual-Wing Wire Mesh stands for Tin-Coated Copper Clad Steel, a composite material engineered to balance conductivity, durability, and cost-effectiveness. This hybrid structure consists of:

1. Inner Steel Core: Provides mechanical strength and structural integrity, ensuring resistance to mechanical stress and environmental degradation.
2. Intermediate Copper Layer: Enhances electrical conductivity, critical for effective EMI/RFI attenuation.
3. Outer Tin Coating: Offers corrosion resistance, solderability, and compatibility with various mounting methods.

This material composition delivers shielding effectiveness (SE) of 45–60 dB across a broad frequency range (100 kHz to 10 GHz) , making it ideal for high-frequency applications where signal integrity is paramount.

Dual-Wing Structural Design

The Dual-Wing architecture is a patented design feature that optimizes both shielding performance and mechanical flexibility:

1. Double-Layer Knitted Mesh: Two layers of interwoven TCS wires create a redundant shielding barrier, minimizing electromagnetic leakage. The unique interlocking pattern ensures uniform conductivity and mechanical stability.
2. Asymmetric Wing Geometry: The “wings” are angled to enhance airflow and reduce eddy currents, critical for thermal management in enclosed systems. This design also improves compliance with irregular surfaces, ensuring consistent contact in dynamic environments.
3. Elastomeric Core (Optional): A silicone or fluorosilicone core can be integrated to provide compression resilience, sealing against dust, moisture, and vibration while maintaining electrical continuity .
