![]() High Temp 16 Pair Type J T/C FeedthroughHigh temperature, vacuum sensor array used in the Aerospace industry. HIGH TEMPERATURE FEEDTHROUGHSHigh temperature environments require vigorously designed seals for ultra-high vacuum (UHV) and high-temperature atmospheres. BCE incorporates the use of both metalized ceramics and active alloy sealing methods. This offers our customer’s the most suitable design for their applications. With various KF and CF flanges, BCE can build and test your application with certification of 1x10-10 cc/sec He and operating temperatures up to 300°C near the feedthrough seal. The bake-out temperature can be as high as 450°C. RIGHT ANGLE VACUUM FEEDTHROUGH![]() Vertex Series FeedthroughHigh vacuum - right angle. The Vertex line of feedthroughs was born out of the necessity of making right-angle feedthroughs robust enough to handle the high vacuum requirements, voltage, amperage, pin dimensions, and challenging space constraints. BCE responded with the Vertex feedthrough. LEARN WHAT A VACUUM FEEDTHROUGH IS...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. Read More...

5 Pin Vacuum Feedthroughs
![]() Need Circular Flange, Pin Contact Feedthroughs? Give BCE a Call!Five pin circular feedthroughs (often called instrumentation feedthroughs) are commonly used for the transmission of low power electrical signals. They are designed for applications where typical Subminiature Type-D connections will not fit, or where there is little space. The circular geometry allows the installation of this feedthrough into very small vacuum flanges. They are often used in instrumentation applications such as semiconductor processing, electron microscopy, and a variety of analyzers. 5 Pin Instrument Feedthroughs by BCEFive Ni-FE alloy, gold plated pin's are sealed and electrically insulated in a stainless steel shell using the latest in ceramic bonding technology. Multiple contact configurations are available. Specifications

Wetted parts constructed of 316 stainless steel with liquid flow passing over an enclosed heated body. All threaded fittings are available such as NPT, SAE, BSP, VCR & more. ![]() Gas Chromatograph HeatersGas Sample and columns heating. GAS CHROMATOGRAPH HEATERSThis specialized category of electric heating element is designed to provide extremely uniform temperature profiles across the length of the GC column. This uniformity accommodates a stable temperature environment for the capture of repeatable and consistent data between runs. Gas chromatograph heaters allow for very precise temperature ramping and set point control to very tight tolerances. This is critical because the slightest fluctuation in column temperature during analysis will have significant effect on analysis outcomes. |

BCE Specialized Ceramic Metallization
![]() Refractory Metallization, Brazing, Contract FiringBCE 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 MetallizationHi-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.BrazingTheir 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 FiringBCE'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.![]() BCE Engineering & Quality AssuranceBCE engineers provide decades of experience in design and development, delivering a wealth of empirical data and experience.
