Finger-Stock Gaskets

Electromagnetic interference can harm electronic devices and people. Consequently, many applications must incorporate EMI shielding to be successful. Improve the performance and longevity of your product with finger-stock gaskets from Microphoto.

The Finger-Stock Gasket Advantage

Finger-stock gaskets are protective components that combine high levels of shielding effectiveness with a broad deflection range and low closure force properties. A typical profile is a long strip with many protruding sections, which are also called fingers or strips, capable of movement. Additional benefits include:

  • High Shielding Attenuation
  • Low Compression Set
  • Excellent Conductivity

Also called finger-strips, these devices are ideal for indoor or controlled environments. Examples include covers or doors subjected to repeated opening and closing.

Industry-Specific Electromagnetic Shielding Solutions 

An ISO 9001:2015 compliant and ITAR-registered contract manufacturer and value-added service provider, Microphoto is trusted by clients operating across all types of industries to fabricate custom finger-strip gaskets for their application.

Materials That Work

The most common materials used to make finger-stock gaskets are beryllium-copper and stainless steel. Each one has unique performance characteristics that are beneficial for specific uses.  Offering high tensile strength, an extreme operating temperature range, and superb electrical conductivity, beryllium-copper is ideal for applications requiring shielding over broad frequency ranges.

Stainless steel, however, exhibits good tensile strength and has an extreme operating temperature range. It also has a high compression set, which is perfect for rugged applications.

Turnkey Production

At Microphoto, we specialize in manufacturing finger-stock gaskets using your print, specification, or purchase order requirements. If you have a specific shielding need but no documents to go off of, we’ve got you covered there, too. Our experts will work with you to develop a concept and make a prototype. Once the design is proved out and acceptable, full-scale production kicks off.
