gs5200 emi gaskets

Summary

adhesive-backed, EMI gasketing material that is ideally suited for

wireless infrastructure and telecommunications applications.

part forms or in slit width rolls. Slit width material is ideal for

manual “peel and stick” EMI gasketing applications.

PTFE matrix, a conductive pressure sensitive adhesive, and a PET

carrier film (see Figure 1).

Applications

EMI shielding for wireless infrastructure equipment,

telecommunications equipment, in addition to specialized

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
