Frequently Asked Questions
1. What is EMI shielding?
EMI shielding (electromagnetic interference shielding) is the process of protecting electronic equipment from unwanted electromagnetic signals that can disrupt performance. It typically involves using conductive materials and shielding gaskets to block or reduce interference and ensure compliance with EMC (electromagnetic compatibility) standards.
2. What are EMI shielding gaskets used for?
EMI shielding gaskets are used to seal gaps between components while maintaining electrical conductivity. They are commonly used in:
- Aerospace and defence electronics
- Communication systems
- Shielded enclosures and cabinets
- Industrial and medical equipment
These gaskets help prevent signal leakage and protect sensitive systems from external interference.
3. What types of EMI shielding solutions are available?
A wide range of EMI shielding and EMC solutions are available, including:
- Conductive elastomer gaskets
- Form-in-place (FIP) conductive gaskets
- Conductive foam gaskets
- Finger stock and wire mesh shielding
- Metal foils and woven wire mesh materials
Each solution is designed for specific applications, environments, and performance requirements.
4. Why are EMI shielding solutions important in aerospace and defence?
In aerospace and defence applications, electronic systems must operate reliably in environments with high levels of electromagnetic activity. EMI shielding solutions help:
- Maintain signal integrity
- Prevent system malfunction or failure
- Ensure compliance with strict military and aerospace standards
This makes them critical for mission-critical systems and safety.
5. What materials are used in EMI shielding gaskets?
Conductive gasket materials typically include:
- Silicone or elastomers filled with conductive particles (e.g. silver, nickel, graphite)
- Metal-based materials such as beryllium copper finger stock
- Conductive foams and fabric-over-foam solutions
These materials provide both electrical conductivity and environmental sealing.
