Vanguard Microbridge® Shielding Gaskets

Vanguard 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 from Vanguard. The versatility of the Microbridge® technology permits an almost unlimited variety of custom modifications. From a simple sheet or strip configuration, die-cut conductive gaskets for I/O panels and similar applications are quickly and easily manufactured. Hand cut prototypes and short runs are practical with costeffective minimal tooling.

Standard tooled profiles are shown below; strips, D-bulbs and T-wiper styles. Custom layouts of the conductive traces and die-cutting are easily arranged

Microbridge Strips: 

The D-bulb configuration at left is a closed cell sponge core with an interior vertical conductive silver silicone trace terminated at an exterior conductive pad on both top and bottom surfaces.

 

Microbridge D-bulbs: 

The strip configuration at left is a closed cell sponge core with periodic vertical conductive silver traces which can be positioned at various integrals along the strip width with an exposed conductive pad on both top and bottom strip surfaces. Excellent for I/O panels with die-cut openings

 

Microbridge T-wiper: 

The T-wiper configuration at left is a dense elastomer core with an interior vertical conductive silver silicone trace terminated at an exterior conductive pad on both top and bottom surfaces. The design maximizes the active surface for pressure sensitive adhesive tape mounting.
