Summary
GORE-SHIELD® GS500 EMI Gasket is 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).
Features and Benefits
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).
Gore application engineers can provide expert design assistance
and rapid prototyping for your EMI shielding needs. Contact Gore
for additional information.
