FINGERSTOCK GASKETS AND METAL GROUNDING PRODUCTS
As the world’s leading fabricator of fingerstock, Laird Technologies has developed highly
sophisticated, and often proprietary, shielding and grounding technology.
Our innovations are necessary to achieve outstanding combinations of performance parameters.
From a vast selection of product configurations, platings and mounting techniques, to a full range
of low compression force requirements and high transfer impedance characteristics, there is a
Laird Technologies gasket or grounding product just right for the job.
These versatile gaskets are made from high-performance beryllium copper with Sticky Fingers®
self-adhesive backing. They provide an extremely tight, instant bond and are ideal as an all-purpose
ALL-PURPOSE SERIES
contact strip for metal cabinets and electronic enclosures, particularly where space is critical.
