GORE-SHIELD® GS500 EMI Gaskets

GORE-SHIELD® GS500 EMI Gaskets are a conductive, adhesive backed, EMI gasketing material that is moderately soft and is ideally suited for wireless infrastructure and telecommunications applications.

GORE-SHIELD® GS500 EMI Gaskets can be supplied in die-cut part forms or in slit width rolls. Slit width material is ideal for manual “peel and stick” EMI gasketing applications.

GORE-SHIELD® GS500 EMI Gaskets consist of a carbon-filled cellular PTFE matrix, a conductive pressure sensitive adhesive, and a PET carrier film (see Figure 1).

Applications

EMI shielding for wireless infrastructure equipment, high frequency cable connectors, and telecommunications equipment in addition to portable electronic devices.

Design Considerations

When optimizing a gasket shielding solution, consider the housing design as well as the EMI gasket performance.

Important considerations in the housing design include flatness, surface roughness, material type, rigidity, contact area, tolerance take-up, conductivity, fastener type, and fastener locations.

Key factors in an EMI gasket include softness, tolerance take-up, conductivity (DC resistance), and shielding effectiveness both before and after Accelerated Life Testing (ALT).
