When selecting a Wire Mesh Gasket, many engineers focus primarily on dimensions and material type.
Unfortunately, this often leads to poor EMI shielding performance.
Do not select an EMI Wire Mesh Gasket based on dimensions alone.
Do not assume all wire mesh gaskets perform equally.
Compression Is Critical
One of the most overlooked factors in gasket performance is compression.
A Knitted Wire Mesh Gasket must maintain sufficient contact pressure to create an effective conductive seal.
Too little compression can result in:
- Increased leakage
- Reduced shielding effectiveness
- Poor electrical continuity
Too much compression can damage the gasket structure.
Material Selection Matters
Different applications require different materials, including:
- Tin-plated copper-clad steel
- Monel wire
- Aluminum wire
- Stainless steel wire
Do not select material based solely on cost.
Material choice affects:
- Corrosion resistance
- Shielding performance
- Environmental durability
Installation Can Determine Success or Failure
Even a high-performance Shielding Wire Mesh Gasket can fail if installed improperly.
Common mistakes include:
- Uneven compression
- Poor mating surfaces
- Insufficient fastening points
- Surface contamination
EMI shielding performance depends on the entire assembly, not just the gasket itself.

Conclusion
Selecting the correct EMC Wire Mesh Gasket requires more than matching dimensions.
Do not overlook compression, material selection, and installation quality when evaluating shielding performance.
