Custom Vacuum Feedthroughs by BCE
BCE Epoxy Vacuum Feedthroughs

Designer, why conform your designs to a vendor spec, when BCE will adapt to yours?

Sixty years of high-tech design experience in semiconductor equipment, medical equipment and R&D yields one of BCE's most innovative products.

Equipment manufacturers and scientific researchers are continually challenged with supplying power, fiber-optic, control, and monitoring cables into (and out of) sealed vacuum vessels. Whether due to space restrictions, special geometries, or number and type of conductors, standard glass-to-metal or ceramic feedthroughs never quite fit the bill. Unfortunately, because of limited options, many designers are forced to compromise and go for an off-the-shelf solution.

You don't have to compromise anymore.

Epoxy to the rescue. During the past decade, new epoxy compounds have been developed that rival glass and ceramic in performance. BCE is at the forefront of this development and leverages modern epoxy's unique properties to solve your feedthrough challenges.

With modern epoxy feedthroughs, any kind of standard or custom connector is sealed in a completely potted, high-performance, clear epoxy compound. Epoxy seals offer countless design options, and most amazingly, performance equal to or better than glass or ceramic. Better yet, pricing is very competitive and quick turn-around for prototypes and short production runs are not a problem.

BCE custom epoxy vacuum feedthroughs offer the best choice in application flexibility, cost, and high performance. Epoxy feedthroughs are the right product for today’s fast moving markets. If you have to pass an electrical, pneumatic, or fiber-optic signal through a vacuum chamber wall, THINK OF BCE!

The Advantages of Epoxy Feedthroughs Over Glass and Ceramic

  • Custom shapes, angles and conductors no problem.
  • Run wires (and shielding), pneumatic tubing, or fiber-optic cables.
  • Cost effective compared to glass and ceramic.
  • Short runs and prototypes available quickly.
  • Meets NASA specs on outgassing.
  • Clear epoxy allows for visual inspection.
  • Mounting directly to printed circuit boards and flex-circuits.
  • Eliminates voltage drop or contact resistance.

Flexibility in Design - BCE Thick Film Technology

Need a high performance electric heater in a low mass, low profile package? Need to put high watt density in a small space? Or maybe you need to distribute wattage disproportionately to an irregularly shaped part? Chances are BCE can develop the perfect heater for your needs.

BCE ceramic thick film heaters are easily customized into a variety of shapes and sizes, and provide excellent heat transfer. Long life is assured by precise thermal matching between ceramics and resistor traces.


Excellent Choice for Many Industries

The ceramic substrates provide excellent hardness, wear resistance, and compression strength. The physical properties of the ceramic also provide optimal thermal conductivity and excellent uniformity. Thick film ceramic heaters are perfect for application in analytical equipment, life science equipment, mass spectroscopy, medical devices, semiconductor processing, packaging machines, and in applications ultra pure and chemically aggressive media.

Key Benefits

  • Virtually unlimited in shape or size.
  • Single or double sides, one or two layers per side.
  • High purity applications no problem.
  • Precise control and uniformity via custom watt densities and patterns.
  • Distributed wattage for ideal application of heat to part with minimal losses.
  • Multiple heating zone capabilities for more precise control.
  • Available in virtually any voltage, AC or DC.
  • Integrated sensors including thermistors, thermostats, thermal fuses, and printed RTD's.
  • Wide variety of lead configurations conforming to shock and vibration, vacuum and purity standards.

BCE Specialized Ceramic Metallization

Refractory Metallization, Brazing, Contract Firing

BCE has specialized in ceramic metallization since 1988. Their engineers and team combines for decades of experience in the research and development needs of the semiconductor and other high-tech industries. BCE performs precision machining and grinding services on ceramics and quartz. Materials are processed, measured and cleaned with state-of-the-art equipment by highly trained professionals. All parts are designed and fabricated to the customer’s specifications. We perform the following services on ceramics and quartz materials:


Refractory Metallization

Hi-Temp Refractory metallization is the only solution for some packaging applications. Tungsten and Moly-Manganese metallizations have higher adhesion to the substrate than Thick-film metallization. This makes it the ideal process for Hermetic packages, Brazed lead frames and packages requiring high operating temperatures. BCE can screen print, spray or hand-paint these metals onto Alumina Oxide or Beryllium Oxide substrates. These patterns can be plated with Gold and Nickel or Gold alone. Once Gold plated, these surfaces are solderable and wire bondable with Aluminum or Gold wire.

Brazing

Their batch furnaces are ideal for accurate brazing of small quantities and large. They can braze Kovar, Stainless Steel, Copper and Copper/Tungsten as well as many other metals to metallized ceramic. When the application requires, BCE can step-braze to combine several sub-assemblies into the final product. BCE has experience designing and brazing Pins and Sockets into holes, ring frames, lead frames and heat sinks.

Contract Firing

BCE's furnace capability allows them to offer contract firing. Their controlled atmosphere batch furnaces can be used for large volume soldering, glass sealing, epoxy curing and Nickel and Gold sintering. Their programmable Cold Wall furnaces operate at temperatures up to 1500° C in a reducing atmosphere.
