EMI shielding elastomers Vanguard microbridge

MicroBridge Gaskets

Microbridge® is the ultimate construction design utilizing new technology which creates a microscopic conductive bridge through the body of an elastomeric extruded gasket. The conductive element traces a path, by putting the conductor only where it is needed through the interior of the silicone rubber core, yielding very significant cost- effective savings of the conductive material.

This leaves the outside face of the mounting surface side with as much adhesion-active area as possible and improved galvanic corrosion resistance with low compression/ deflection forces. Excellent for I/O backplanes and all general RFI/EMI shielding applications.

Available in most profiles in this catalog and many custom configurations. Be creative and utilize our design staff to help optimize your specific application. Standard tooled profiles: strips, D-bulbs and T-wiper styles. Custom layouts of the conductive traces and die-cutting are easily arranged (see also custom die-cuts below).

Frequently asked questions and answers about EMI Shielding

What is EMI shielding?

EMI shielding is the process of protecting electronic devices from electromagnetic interference (EMI) by using materials that block or reduce the electromagnetic fields. This ensures the proper functioning of electronic equipment by preventing external EMI from disrupting their operation.

Why is EMI shielding important?

EMI shielding is crucial because electromagnetic interference can cause malfunctions, data corruption, and signal degradation in electronic devices. Effective EMI shielding ensures the reliability and performance of electronic systems, particularly in environments with high electromagnetic activity.

What materials are commonly used for EMI shielding?

Common materials for EMI shielding include metals like copper, aluminum, and steel, as well as conductive coatings, conductive elastomers, conductive foams, and fabric-over-foam gaskets. These materials are chosen for their ability to block or attenuate electromagnetic fields.

How do conductive elastomers work in EMI shielding?

Conductive elastomers are made of silicone or other elastomeric materials embedded with conductive particles, such as silver, nickel, or carbon. These elastomers provide both EMI shielding and environmental sealing, making them ideal for protecting electronic enclosures and components.

What are the applications of EMI shielding?

EMI shielding is used in a wide range of applications, including automotive electronics, aerospace systems, telecommunications equipment, medical devices, consumer electronics, and industrial control systems. It is essential wherever electronic devices need to be protected from electromagnetic interference.

What is the difference between conductive foam and fabric-over-foam gaskets?

Answer: Conductive foam consists of a foam core coated with a conductive material, providing flexibility and EMI shielding. Fabric-over-foam gaskets combine a conductive fabric layer with a foam core, offering superior shielding effectiveness, cushioning, and easy installation in electronic assemblies.

How do you choose the right EMI shielding solution?

Choosing the right EMI shielding solution involves considering factors such as the level of EMI protection required, the operating environment, mechanical properties, and ease of installation. Consulting with an expert can help determine the most suitable material and configuration for your specific application.

What are the benefits of using dual-elastomer gaskets for EMI shielding?

Dual-elastomer gaskets, like the Ultra-Vanshield® series, offer the advantages of a durable silicone core combined with a highly conductive outer layer. This design provides excellent EMI shielding effectiveness, low compression set, environmental sealing, and resilience to mechanical stress.

Can EMI shielding solutions be customized?

Yes, EMI shielding solutions can be customized to meet specific requirements. Customizations can include the shape, size, material composition, and performance characteristics of the shielding components. Custom solutions ensure optimal protection for unique applications and environments.

What should you consider when installing EMI shielding?

When installing EMI shielding, consider factors such as the compatibility of materials with the operating environment, the effectiveness of the shield in blocking EMI, ease of installation, and the mechanical integrity of the shielded assembly. Proper installation techniques are crucial to achieving optimal EMI protection.
