Frequently Asked Questions

Q: What is the primary function of metal honeycomb vents in EMI shielding?

They act as a waveguide-below-cutoff, allowing air to pass through for cooling while blocking electromagnetic waves from entering or exiting the shielded enclosure.

Q: Which materials are best for harsh marine environments?

For marine applications, we recommend SUS316L stainless steel or specialized coatings like electroless nickel plating to prevent salt-spray corrosion.

Q: How does vacuum brazing improve the vent's performance?

Vacuum brazing creates high-strength, leak-proof joints between the honeycomb core and the frame, ensuring no RF leakage occurs at the seams.

Q: Can the cell size be customized for specific frequency ranges?

Yes, cell size is critical for shielding effectiveness. We offer a wide range from 0.8mm to 8mm to meet specific frequency attenuation requirements.

Q: What is the typical lead time for custom EMI honeycomb panels?

For quantities below 50 pieces, the standard delivery time is 4-6 weeks, depending on the complexity of the customization.

Q: Do you provide EMI gaskets with the ventilation panels?

Yes, we provide customized EMI gaskets to ensure a perfect seal between the honeycomb panel and the mounting surface, maximizing shielding performance.
