Shielding strips are required by a wide range of industries for a variety of applications. When you need standard EMI shielding strips, think of Tech Etch.
Tech Etch offers the most complete line of standard BeCu shielding strips in the industry. They are available in strips ranging from 16 to 24 inches in length, in continuous coils up to 35 feet long, as single fingers, or cut to requested full-finger lengths. Consult our engineering department for special modifications to suit your requirements.
Standard finger stock uncompressed heights range from .03″ to .44″, which will occupy gaps as low as .01″. Many gaskets are offered in two material thicknesses to meet diverse application compression requirements: “Standard” and “TF”, which requires less force to compress the gasket to its operating range.
EMI Shielding Compatibility
- Electromagnetic Compatibility – EMI/RFI Shielding Products are designed to either keep out or keep in electromagnetic interference. Shielding reflects and absorbs incident radiation. The higher the attenuation of the shielding, the more effective it is at keeping in or out the undesired electromagnetic interference.
- Electrochemical Compatibility – To avoid galvanic action between contacting metals refer to this chart. Materials in adjacent groups may be safely used together. Choosing materials from within a single group in the table will provide the least corrosion due to galvanic action when the materials are in contact for an extended period of time with appropriate protective finish.
Tech Etch offers a range of vent filters for various uses and a variety of industries. Their aluminum alloy, neoprene sponge, and other materials provide durable and long-lasting results for your vent filtration needs.
800 Series Honeycomb Vents
The 8000 Series Vents are manufactured in both customized and standard configurations. Shielding performance is achieved from 1/8 cell aluminum honeycomb panels mounted in high strength extruded aluminum frames available in 14 sizes. Frame to enclosure shielding options include Twinseal, Mesh gaskets, Beryllium copper shielding strips or Metalized Fabric Gaskets. Shielding effectiveness and environmental protection can be improved by plating with tin or nickel. The highest level of shielding is achieved with a cross cell configuration where two 1/4 thick honeycomb panels are assembled with the foil seams oriented 90 degrees from each other. Standard vents are available in Frame 01 with 8-32 threaded blind inserts for mounting. For custom requirements, frame, frame to enclosure shielding, finish and dimensional specifications are required.

8200 Series Shielded Fan Vents
The 8200 Series Shielded Fan Vents with optional dust screens are designed to provide EMI shielding and maximum air flow without degrading the fan output. These vents provide a low cost option to perforated metal when airflow rates
are critical. Tech Etch stocks fan vents in 6 sizes corresponding to industry standard fans with standard 4-hole mounting. Shielding performance is achieved from 1/8 cell aluminum honeycomb panels mounted in high strength extruded aluminum frames with beryllium copper shielding strips for shielding the frame to the enclosure. Dust screens consisting of multilayer expanded aluminum can be added, but airflow will be restricted.
8500 & 8900 Series Shielded Air Filters
Aluminum Mesh Shielded Air Filers 8500 – Shielded filter and dust shields perform three functions: they attenuate EMI, they provide for a passage of cooling air, and they filter dust from the air flow. Designed for use in industrial environments at low to medium air flow rates, they can be cleaned either by immersion and agitation in a suitable solvent or by air blasting. The filter is comprised of three layers of corrugated aluminum mesh aligned to provide maximum dust trapping effectiveness and minimum resistance to airflow. The filter material is contained in a rigid “C” channel aluminum frame of all welded construction and protected on each side with an expanded metal grid.
Electronic filters and dust shields are manufactured to meet the needs of individual applications. For custom requirements, please supply a detailed drawing with the following information:
- Location and size or type of fixing holes or inserts (6/32 or 8/32 UNC, preferred).
- Outer dimensions of filter.
- Type of gasket required
Thin Screen Shielded Air Filters 8900 – Composed of expanded multi-layer aluminum, Thin Screen Shields combine the functions of EMI shielding with efficient dust filtering and ventilation. Thinner than electronic filter dust shields, they provide better dust extraction, but with greater restriction of air flow. They cost less than electronic dust shields and honeycomb.
