Abstract

Disclosed here is a small easily retrofit internal box-to-box grounding gasket for electromagnetic compatibility (EMC). The gasket os comprised of a v-shaped, one winged piece of tin or tin/lead plated copper/polymide laminate, (a) in the figure, i.e., a piece of flexible printed circuit carrier. The copper provides a conductive path, with the tin or tin/lead plating providing galvanic compatibility with the aluminum or zinc plated surfaces commonly used in electronic equipment. A strip of adhesive (b), applied during manufacture of the gasket, is present on the "wing" section on the metallized side. This adhesive provides the means of keeping the gasket physically in place without the need for mounting holes or other latching points on the surfaces to be grounded.

Small Profile Internal Box to Box Electromagnetic Compatibility Grounding Gasket

      Disclosed here is a small easily retrofit internal box-to-box
grounding gasket for electromagnetic compatibility (EMC).  The gasket
os comprised of a v-shaped, one winged piece of tin or tin/lead
plated copper/polymide laminate, (a) in the figure, i.e., a piece of
flexible printed circuit carrier.  The copper provides a conductive
path, with the tin or tin/lead plating providing galvanic
compatibility with the aluminum or zinc plated surfaces commonly used
in electronic equipment.  A strip of adhesive (b), applied during
manufacture of the gasket, is present on the "wing" section on the
metallized side.  This adhesive provides the means of keeping the
gasket physically in place without the need for mounting holes or
other latching points on the surfaces to be grounded.  Finally, a
v-shaped compliant elastomeric strip (c) is used to provide the
contact force between the gasket and the mating surfaces.  In (d), in
the figure, the gasket is shown as it might be used, positioned
between an interior box, such as a power supply, and the internal
frame.
