Ceramic and standard glass-to-metal feedthrough do not
fulfill the requirements that challenge scientific researchers and equipment
manufacturers. Challenges include supplying monitoring cables in and out of
sealed vacuum vessels, and supplying control, fiber-optics, and power to those
vessels. The type and number of conductors, special geometries, and space
restrictions cause the most problems.
New custom epoxy feedthroughs have been developed that rival
ceramic and glass in performance. Modern epoxy feedthrough qualities solve the
challenges that are presented. Connectors, sealed in standard or custom epoxy
feedthroughs, are potted in a high-performance, clear epoxy compound. Countless
designs are available that perform as well or better than ceramic or glass.
Short production epoxy feedthrough runs do not present a problem. Making
prototypes can be done with a quick turn-around. The price of custom epoxy
feedthroughs is very competitive.
‘Clear’ Advantages to an Epoxy Feedthrough
- · Custom conductors, angles, and shapes are not a problem.
- · The prototypes have fiber-optic cables, pneumatic tubing, or run wires and shielding.
- · Compared to ceramic or glass, custom epoxy feedthroughs are cost-effective.
- · NASA outgassing specs are met.
- · Visual inspection is possible because of the clear epoxy used.
- · The feedthroughs can be mounted directly to flex-circuits and printed ciruit boards.
- · Contact resistance and voltage drop is eliminated.
Fewer connectors and components are needed. Often five
components can be reduced to one. Epoxy feedthroughs eliminate potential
failure points. Today’s fast moving market requires custom prototypes that are
designed with high vacuum performance. When high integrity feedthroughs are
required, custom epoxy feedthroughs should be considered.
