Frequently Asked Questions

Q: What is the primary function of EMI Honeycomb Vent Panels?

These panels allow for critical air ventilation and cooling in electronic enclosures while simultaneously blocking electromagnetic interference (EMI) and radio frequency (RF) signals from entering or exiting the shielded area.

Q: Which materials are best for marine environment applications?

For marine environments, we recommend SUS316L stainless steel or aluminum with specialized surface coatings like electroless nickel plating or powder coating to prevent saltwater corrosion.

Q: Can these panels be customized for specific frame types?

Yes, we offer "L", "C", and "H" type frames to suit different installation requirements, and all dimensions can be customized to fit your specific shielded tent or cabinet.

Q: What is the benefit of high-temperature vacuum brazing over spot welding?

Vacuum brazing provides a more uniform and stronger bond across the entire honeycomb structure, improving both the mechanical strength and the electrical conductivity for better EMI shielding.

Q: Do these products comply with environmental standards?

Absolutely. Both our spot welding and vacuum brazing technical processes are fully compliant with ROHS standards, ensuring they are safe and environmentally friendly.

Q: What core sizes are available for RF shielded vents?

We offer a wide range of core sizes starting from 0.8mm up to 30mm, allowing clients to choose the specific cell size required for their frequency attenuation needs.
