Frequently Asked Questions

Q: What is the primary function of a Honeycomb Vent in EMI shielding?

It allows for necessary air ventilation and cooling in electronic enclosures while acting as a waveguide beyond cutoff to block electromagnetic interference (EMI) and radio frequency (RF) signals.

Q: Why is high-temperature vacuum brazing preferred over spot welding?

Vacuum brazing provides a more uniform and stronger bond across all cell walls, significantly improving the structural integrity and RF shielding effectiveness of the panel.

Q: Can these panels be used in corrosive marine environments?

Yes, by selecting materials like SUS316L or applying specialized surface coatings such as electroless nickel plating, our vents offer excellent corrosion resistance for marine applications.

Q: How do I choose the correct cell size for my project?

Cell size affects both airflow and the frequency range of the shielding. Smaller cells provide better shielding for higher frequencies, while larger cells allow more airflow. Our experts can help you calculate the ideal size.

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

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

Q: Are the products compatible with ROHS standards?

Absolutely. All of our welding techniques and material sourcing are fully compliant with ROHS standards to ensure environmentally friendly and safe solutions.
