Fingerstock (CuBe) Gaskets

Leader Tech’s beryllium copper fingerstock gaskets provide a solution for enclosure shielding needs. These highly resilient gaskets are available in a wide variety of profiles including slot mount, clip on, adhesive mount, and low profile options. In addition, Leader Tech can provide parts plated to meet a project's exact requirements.

EMI designers know and trust the consistent performance of fingerstock (CuBe) gaskets. To date, CuBe yields the best electrical spring contact available in this industry. The copper beryllium mills have well established techniques and for decades have produced CuBe alloys per ASTM, SAE, JIS, and DIN specifications.

Leader Tech uses only proven technology in creating copper beryllium springs, contacts, and gaskets. Beginning with Alloy 25 (1/4 hard) BeCu, they stamp, form, and post heat-treat to a hardness of 340 DPH to 390 DPH. This process is preferred in the EMI shielding industry because it has proven to produce the best electrical spring contacts. Leader Tech CuBe EMI shielding gaskets are the most reliable in the industry.

Leader Tech manufactures a wide variety of standard styles and sizes of CuBe gaskets. These gaskets operate in spaces from 0.010 inches up to 0.410 inches. Using CuBe materials as thin as 0.002 inch, they also offer many styles as soft gaskets that provide the low compression force needed in many applications. Leader Tech also designs and manufactures custom spring contacts and gaskets. 

Fingerstock gaskets do two things very well: their mechanical spring characteristics far surpass all other gaskets in the industry, and they offer the highest EMI shielding effectiveness.

Leader Tech's innovative fingerstock gasket designs are a direct result of their experience and customer input. The Compact PCI line of EMI Gaskets is an example of a design that was driven by the needs of a customer and evolved into a line of gaskets that meet all the requirements for Compact PCI faceplate standards while providing superior mechanical and shielding performance.

Leader Tech offers many standard off-the-shelf fingerstock gaskets as well as the engineering and custom manufacturing experience to help solve project application needs.
