BeCu Fingerstock

Schlegel Electronic Materials, the pre-eminent manufacturer of fabric over foam EMI shielding products, offers a complete line of quality beryllium copper (BeCu) EMI gaskets. The addition of the BeCu gaskets to Schlegel Electronic Materials’ extensive portfolio allows Schlegel Electronic Materials to be your exclusive EMI shielding supplier, to help you meet or exceed your global requirements for electromagnetic compatibility (EMC).

The mechanical spring characteristics of BeCu EMI gaskets offer superior shielding effectiveness. These gaskets offer consistent performance and yield superb electrical spring contact within this industry.

Schlegel Electronic Materials provides all the popular standard styles and sizes of BeCu gaskets.
The gaskets operate in spaces from 0.010 inches up to 0.500 inches.

Schlegel Electronic Materials also offers many styles of soft gaskets that provide the low compression force
needed in many applications. Custom spring contacts and gaskets are also available.

Available from Schlegel Electronic Materials is the new PCI-VME series, which was developed to improve the seal between Compact PCI circuit card faceplates. The PCI-VME series offers the following design features

  • A series of individual fingers to achieve maximum conformal contact.
  • A single radius dome top profile to ease card loading and eliminate high stress in the contact area of the spring.
  • The industry standard manufacturing process for BeCu fingerstock gaskets (post heat-treated and post-plated alloy 25).
