GORE EMI Gaskets and Grounding Pads

Electronic Components & Electrochemical Materials

GORE® EMI Gaskets and Grounding Pads are available in two different materials, the GS5200 Series offers excellent EMI shielding effectiveness from low frequency to 40 GHz. The GS2100 Series, approved for military aerospace and spaceflight applications, combines good shielding effectiveness with light weight and low outgassing.

Overview

The GS5200 Series die-cut into gaskets, ideal for telecommunications and wireless infrastructure equipment.

The GS5200 Series die-cut into gaskets, ideal for telecommunications and wireless infrastructure equipment.

In telecommunications applications, EMI gaskets are exposed to a variety of environmental factors, including extreme temperatures and precipitation. Despite this exposure, EMI gaskets need to provide reliable shielding and conductive performance over time to ensure electrical integrity.

 

The GS5200 Series of GORE EMI Shielding Solutions is a highly conductive, adhesive-backed EMI gasket material ideally suited for wireless infrastructure and telecommunications applications. Flame-retardant and engineered to withstand temperatures from -55°C to 125°C, the gaskets ensure electrical integrity in harsh environmental conditions.

 

The gaskets’ PTFE construction provides durability, thermal stability and superior shielding effectiveness.

The gaskets’ PTFE construction provides durability, thermal stability and superior shielding effectiveness.

Applications

Durable and thermally stable, the GS5200 Series is typically used in:

  • wireless infrastructure equipment
  • telecommunications equipment
  • specialized portable electronic devices

Features & Benefits

The GS5200 Series materials consist of a nick-filled PTFE matrix, a conductive pressure-sensitive adhesive and a PET carrier film. The materials can be supplied in die-cut part forms — or in slit-width rolls, which is ideal for manual “peel and stick” EMI gasket applications. Because of this three-layer construction and the use of PTFE, our gaskets offer:

  • excellent shielding effectiveness
  • excellent reliability through Accelerated Life Testing (ALT)
  • flame-retardancy (UL-94 V-0)
  • broad temperature range (-55°C to 125°C)

The GS5200 Series is successfully used worldwide. If you have any questions about EMI shielding materials, please contact us.

Properties

The GS5200 Series reliably offers these nominal material properties:

Hardness Density (gm/cc) Operating Temperature Fire Safety Rating (UL-94)
(Shore A) 60 1.95 -55°C to 125°C V-0

The series’ electrical properties include superior volume resistivity and shielding effectiveness:

Volume Resistivity (25% compression, Ag electrodes) Shielding Effectiveness(with adhesive)
0.04 ohm-cm (without adhesive) > 90 dB(ARP 1705 Method)

 

Thickness

The GS5200 Series is available in a range of thicknesses:

In. Mm.
0.015 0.38
0.024 0.61
0.030 0.76
0.048 1.22
0.060 1.52

 

RoHS Compliance

The GS5200 Series has been tested for RoHS compliance. W. L. Gore & Associates, Inc. declares that we do not intentionally add any of the substances listed below in Directive 2011/65/EC, Directive 2002/95/EC and directive 2003/11/EC to the GS5200 Series of GORE EMI Shielding Solutions. Gore certifies that the parts listed are allowable threshold levels for the materials listed in the following table.

RoHS Material Pass/Fail
Lead (Pb) Content Pass
Cadmium (Cd) Content Pass
Hexavalent Chromium (Cr6) Content Pass
Mercury (Hg) Content Pass

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. Please contact us for more information about the right solution for your design needs.
