ALUMINIUM HONEYCOMB AIR VENTILATION PANELS FOR RFI/EMI SHIELDING Product Overview Kemtron Limited (Kemtron), now part of TE Connectivity, manufactures a range of aluminum honeycomb air ventilation panels consisting of an aluminium honeycomb foil held in a rigid extruded aluminium mounting frame. The foil, formed and laminated into a series of honeycomb cells that are glued and perforated or laser welded at the join, ensures a conductive path at each join. Although the foil is conductive in all directions, to enhance EMI performance, two pieces of honeycomb polarised at 90° to each other are recommended. The frame can be supplied with an integral or separate EMI/RFI gasket, and can be treated with a variety of finishes to provide corrosion protection or improve conductivity. How do honeycomb vents work The principle is that of “waveguide beyond cutoff”. The honeycomb vent is series of tubes that acts as a waveguide, guiding electromagnetic waves into or out of the enclosure, but as the tubes are long enough then it attenuates those waves. Typically the tube should be at least 3 times as long as the diameter. Good practice is 4 times. Therefore a 3.18mm cell should be 12.7mm long. Honeycomb material is used because it offers high shielding performance, light weight and good airflow. A standard range of honeycomb vents are available, drawings and part numbers are shown at the end of this data sheet. Applications Ventilation panels are designed for use in electronic enclosures where good air flow is required for cooling and ventilation but where EMC compliance must be ensured. Typical applications are: • • • • • Electronic Enclosures Air Conditioning Units Fan Housings EMC Racks Communication Shelters Availability An extensive range of aluminium extrusion mounting frames are available from stock offering a choice of mounting methods and sizes. Available as custom sizes with no additional cost. Frames can be supplied with fixing holes or captive threaded inserts to aid mounting. Honeycomb can be supplied in a number of configurations to suit different EMI/RFI shielding performance requirements, such as straight through, polarized and a choice of cell size. Standard perforated honeycomb is available with 30˚, 45˚, 60˚ and 90˚ angles from stock and laser welded aluminium honeycomb is also available to special order. For vulnerable situations, weld mesh or expanded aluminium kick plates can be fitted. Removable dust filters and integral insect screens can also be provided. A range of low cost standard fan vents are available to meet commercial applications where lower performance is acceptable, consisting of one layer of aluminium honeycomb held in a plastic frame. PERFORMANCE MATERIALS / ALUMINIUM HONEYCOMB AIR VENTILATION PANELS FOR RFI/EMI SHIELDING 2 Design Considerations Any environmental conditions such as moisture and dust control including: • Air flow requirement • External louvres for rain protection • Drain holes • Any additional gasketing Constructional Requirements and Finishes Including • Angled honeycomb for rain protection or directional air flow • Rigidity of vent frame and enclosure so as to prevent bowing of either surface when compressing the gasket • Fixing requirements e.g. holes or threaded inserts ensuring appropriate position and size of hole-centres, (Holes in the corners of the frame should be avoided) • If specifying captive inserts in both sides of the frame, offset the positions by 10mm minimum • Round vents tend to be an expensive option due to the complexity of manufacturing method • Fully welded corners • Type of gasket required • Frame style • Honeycomb configuration • Corrosion, electrical conductivity etc, (see Finishes section) • Weld mesh or expanded aluminium kick plates • Removable dust filters and integral insect screens can be provided Production Capabilities Kemtron manufactures its range of EMC vent panels using the latest technology and, with the exception of painting and plating, all processes are kept in house, giving us flexibility and total control over quality. Kemtron has invested heavily in this area making us the market leaders for price, delivery, quality and availability. Fully programmable CNC machines for the notching & cutting of the frame extrusions and drilling of exact and repeatable holes combined with the latest TIG welding equipment allows Kemtron to offer a fast delivery of its competitive range of aluminium vent panels produced to customer designs. This advanced technology also eliminates the need for additional tooling and set-up charges. Kemtron holds a large range of aluminium extrusions and aluminium honeycomb in stock. In addition to vent panels, Kemtron manufactures a huge range of EMI shielding products, including conductive elastomers, oriented wire, knitted wire mesh, connector gaskets. Vent panels made with styles 1701, 1703, 1705, 1706 & 1707 are supplied with 3 corners notched and the 4th joined corner welded and have an external corner radii of 3mm.

It meets all the requirements of MIL-C-7438. Standard straight cell size & thickness held in stock • 3.2mm (0.125”) cell x 12.70mm (0.50”) thick • 3.2mm (0.125”) cell x 6.35mm (0.25”) thick • 1.6mm (0.0625”) cell x 6.35mm (0.25”) thick • 3.2mm (0.125”) cell x 3.2mm (0.125”) thick h h Standard slant cell sizes, angles & thicknesses held in stock • 3.2mm (0.125”) cell x 6.35mm (0.25”) thick x 30˚ angle • 3.2mm (0.125”) cell x 6.35mm (0.25”) thick x 45˚ angle • 3.2mm (0.125”) cell x 6.35mm (0.25”) thick x 60˚ angle PERFORMANCE MATERIALS / ALUMINIUM HONEYCOMB AIR VENTILATION PANELS FOR RFI/EMI SHIELDING Slant Angle 4 Frame Styles Available Frame styles 1701,1702,1703,1704 and 1707 will accommodate: • 2 layers of 3.2 x 6.35mm thick honeycomb • 1 layer of 3.2mm cell x 6.35mm thick and one layer of 3.2mm x 6.35mm thick angled honeycomb • 1 layer 12.7mm thick honeycomb Frame styles 1705 and 1706 will accommodate: • 1 layer of 3.2 or 1.6mm cell x 6.35mm thick honeycomb • 2 layers of 3.2mm cell x 3.2mm thick honeycomb Frame style 1709 main use is for dust filter panels that can be fitted over EMC vent panels, but can accommodate one layer of 3.2 or 1.6mm cell x 6.35mm thick honeycomb, however this is not recommended. Frame style 1708 is a dividing/support bar for large vents. Vents are normally supplied with three notched and one welded corner to achieve the best trade off between cost and performance. This combined with an EMC gasket is normally sufficient for all but the most demanding EMC specifications. In the event that the best possible attenuation is required all corners can be supplied fully welded. Please note that styles 1702 & 1704 are always supplied fully welded due to the nature of their construction. FULLY WELDED CORNER NOTCHED CORNER FULLY WELDED CORNER Finishes Kemtron’s standard finish (Surtec 650) for aluminium vent panels fully meets the RoHS directive. Vent panels can be supplied with a range of finishes, including: • Surtec 650 – Trivalent chromium • Tin or nickel plating • Painted • Alochrome 1200 – Hexavalent chromium Kemtron’s in-house hexavalent chromium process applies a trivalent chromium passivation. The surface finish is conductive with a low contact resistance and meets all requirements of MIL-DTL-5541F Type II Class 3 for corrosion resistance and electrical conductivity. We are also able to offer a comprehensive range of painted finishes to complement our standard Surtec 650 finish. Using industry leading wet paint solutions from Trimite, we offer full painting and preparation to DEF STAN specifications including matt and gloss finishes. In addition we can also offer infrared reflecting (IRR) matte finishes complying with DEF STAN 00-23, 80-166 and STANAG 2338. For less critical/commercial applications requiring a protected finish we recommend polyester powder coating. This is tough material that offers excellent resistance to fresh and saltwater, petrol, linseed and penetrating oils, along with limited resistance to various acids. We are happy to advise on specific examples if required. As the epoxy process is an electrostatic method, it offers excellent penetration of the honeycomb cells, further aiding resistance to corrosion. With both processes, we are able to offer a full range of colors to meet RAL/BS standards.

This is held in place on one side by a stainless steel weld mesh. This frame then mounts on to one side of the honeycomb vent panel by captive screws. Easily removed for cleaning with a mild detergent and rinsed with water. A range of different filter options are available. Aluminium honeycomb vent panels fitted with removable dust filters usually require assisted air flow. Standard filter foam is stocked in two thicknesses to suit the above frame styles. 30, 45 and 60 pores per inch are available, and others to meet specific requirements.
