Scanning Probe Control Panel Feedthrough

Scanning Probe Control Panel FeedthroughAn application was presented to BCE in the high-resolution scanning industry for sealing a control
panel. The panel had over 10 inlet and outlet ports using various DB connectors that required hermetic sealing. The BCE engineers and technician were ready for the challenge since the experience with PCB boards was similar in scope using multiple components.

Scanning Probe Control Panel Feedthrough needed to satisfy the following criteria:

  • <50°C continuous operating temperature
  • Chamber is pressurized
  • Female to female connection panel mount with multiple outputs
  • Pressure rating: <15 psi
  • Hydro test at atmospheric pressure
  • Air test <15 psi


Scanning Probe Control Panel FeedthroughBCE designed an effective panel using BCE-Board Seal epoxy to seal without breaking the chamber or contaminating the outside. The customer saw a noticeable improvement with their resolution, particularly the imaging device. All DB connectors performed well without any residual moisture as seen in prior iterations.

BCE’s Board Seal epoxy’s adhesion was the strongest of any adhesive bond. The viscoelastic nature of the epoxy absorbs vibrations and allows for a better performance by reducing fatigue.

KF40 Flanged, 125 Volt, 15A Female-to-Female Socket Vacuum Feedthrough

KF40 Flanged FeedthroughBACKGROUND

A BCE customer needed to replace a bulky power system located within a chamber.  A custom KF40 three-slot single female receptacle feedthrough was the optimal solution to help reduce size and increase efficiency.


The KF40 Socket Feedthrough needed to satisfy the following criteria:
  • 80°C continuous operating temperature 
  • 125V and 15A
  • Female to female connection
  • Vacuum rating: 10-5
KF40 Flanged Feedthrough

BCE designed a simple yet effective unit using a custom elongated KF40 flange with two three-slot single female receptacles. The customer was able to relocate the power system to the outside chamber increasing the available space within the vacuum chamber while maintaining the desired vacuum rating.

BCE’s Epoxy chemical adhesion, the strongest mechanism of any adhesive bond, made the seal possible.  The viscoelastic nature of the epoxy absorbs vibrations and allows for a better performance by reducing fatigue.

Save Time and Money in the Long Run: Choose a Custom Electric Heater When It Comes to Heating Clean and Ultra-pure Fluids

Custom heater for fluids
Custom heater for clean and ultra-pure fluids (from BCE)
What do the fuel cell, bio-med, laboratory, food, pharmaceutical, medical, semiconductor, and electronics industries all have in common? Applications in their processes requiring a fast responding and accurate high purity fluid heater.

Each of these industries include manufacturing processes that require a small and efficient heating source as a component of their production. These heaters must be ruggedly designed, made from materials immune to process contamination, and be vacuum tight. The heaters will be subject to high temperatures, harsh solvents, and corrosive gases. Many times they must maintain a seal for full vacuum, demonstrate a unique heating profile, and maintain very close control.

Common requirements in these processes:
  • Capable of handling high vacuum.
  • High temperatures.
  • Isolation the process media from heating element.
  • Isolation from other area of contamination.
  • Very accurate control, including internal sensors.
  • Fast heat up and cool down.
Few manufacturers offer electric heaters with all of these features with an off-the-shelf product, so a custom (or semi-custom) heater is required. Heater customization allows for specific application requirement to be addressed. Examples are type of internal sensor (RTD or TC), the use of chemical inert glass liners, a profiled heating pattern, and specific wetted materials.

Using stock screw plug immersion heater for these applications should be avoided. This category of heater will not stand up to the rigors of the application, as they are designed for general industrial service. They are not intended for high purity, will not meet material compatibility requirements, have poor controllability and are bulky in size.

The answer is in a custom high purity fluid heater designed with the specific process in mind.

Benefits of developing a custom fluid heaters are:
  • Available in a variety of voltages.
  • Available in a wide range of watt densities.
  • Temperatures up to 350°C.
  • Effective heated area can be profiled to generate a liner temperature profile.
  • Vacuum compatible up to 1.0 x 10-8  STD. CC/SEC Helium.
  • Can be provided with internal sensors (RTD or thermocouples).
  • Can be glass lined for ultra pure gas application.
Careful review of the application is important and the help of an experienced heater application engineer is required. Choose a vendor with a long, proven track record of success. The outcome of the test, process or product will be infinitely improved.
