Gore-Shield ® gs5200 emi gaskets Summary GORE-SHIELD® GS5200 EMI Gasket is a highly conductive, adhesive-backed, EMI gasketing material that is ideally suited for wireless infrastructure and telecommunications applications. GORE-SHIELD® GS5200 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® GS5200 EMI Gaskets consist of a nickel-filled 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. Features and Benefits •• Excellent shielding effectiveness •• Excellent reliability through Accelerated Life Testing (ALT) 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.
