Vacuum chambers often require tube and thermocouple feedthroughs that allow for specific distances during installation. To address this need, we offer a compression fitting solution, empowering our customers with control over the distance in their installations. Through extensive experimentation, we have designed a feedthrough that enables the maximum quantity of 1/8" compression fittings in a standard KF40 and KF50 flange, while still providing enough distance for necessary compression and disassembly.

Scope:

• Compressible vacuum flange offers the following features:
• Temperature range: 0°C to +180°C (limited by O-ring's maximum temperature capacity)
• Material: Stainless steel 304
• 1/8" compression fitting with a 7/16" hex bored through
• Compression of any 1/8" diameter tubing or sensor
• 304 stainless steel KF40 and KF50 flanges
• He Leak Tested to achieve a leak rate of 1 x 10¯⁸ ATM, CC/sec or better (leak rate after compression depends on the material and wall thickness of the tubing, as well as the strength of compression)

Outcome:

By utilizing a reusable feedthrough, end users can effortlessly introduce new sensors into their systems while maintaining vacuum integrity. These compression fitting feedthroughs provide the flexibility and convenience needed for seamless installations.

The Role of Vacuum Feedthroughs

Vacuum feedthroughs are devices that are used to allow electrical, optical, or fluid connections to pass through a vacuum chamber wall. They are essential in high vacuum applications because they allow for the passage of electrical power, control signals, and other types of data into and out of the vacuum chamber while maintaining the integrity of the vacuum.

There are several reasons why vacuum feedthroughs are important in high vacuum applications. First and foremost, they allow for the passage of electrical power and control signals into the vacuum chamber, which is necessary for operating many types of equipment and instruments that are used in high vacuum environments. For example, electrical feedthroughs can be used to power a vacuum pump, while optical feedthroughs can be used to transmit data from sensors or cameras that are located inside the vacuum chamber.

In addition to electrical and optical connections, vacuum feedthroughs can also be used to transport fluids, such as coolants or process gases, into or out of the vacuum chamber. This is particularly important for applications that require temperature control or precise gas delivery, such as in the case of thin film deposition or material processing.

Another important aspect of vacuum feedthroughs is that they can be designed to minimize the amount of outgassing that occurs, which is the release of gas from the feedthrough material into the vacuum chamber. This is important because outgassing can contaminate the vacuum environment, potentially causing damage to the equipment or samples inside the chamber.

Lastly, vacuum feedthroughs must be designed to withstand the high vacuum conditions and operate efficiently and reliably. These feedthroughs typically consist of a metal or ceramic stem with an epoxy, glass or ceramic seal that allows the electrical, optical, or fluid connection to pass through the vacuum chamber wall. The feedthrough stem must be sealed to the vacuum chamber wall without leaking, while the electrical, optical, or fluid connections must maintain their integrity under the high vacuum conditions.

In summary, vacuum feedthroughs play a crucial role in high vacuum applications, by allowing electrical, optical, or fluid connections to pass through the vacuum chamber wall while preserving the high vacuum condition. They also play a important role in controlling temperature, providing gases and maintain the integrity of the electrical, optical and fluid connections.

The Vertex Vacuum Feedthrough

High Vacuum Feedthrough for Tight Spaces

The new 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.

The feedthrough utilizes precise beaded welds and multiple cure times of the BCE epoxy. After each cure, a vacuum leak test is performed to spec, ensuring feedthrough integrity. Chemical cleaning is BCE’s standard procedure for the Vertex.

BCE Vacuum Feedthroughs Allow you to "Take It All Through the Wall"

The development capabilities for vacuum systems and components are continually refined by advances in analytical methods, medical science, and semiconductor manufacturing. The need for process monitoring and control is growing, and it is becoming increasingly difficult to get the necessary power and control signals into vacuum chambers. In order to pass electrical signals, light beams, or pure gases inside a vacuum chamber, devices referred to as vacuum feedthroughs are used. 

Leakage into or through the vacuum feedthrough can not be tolerated as the vacuum seal is essential to preventing leakage and ensuring process integrity. Glass-to-metal and ceramic-to-metal seals, historically the favored technology, are increasingly troublesome - not because of their performance, but because they are limited by size, design, durability, and electro-magnetic shielding choices. Due to this fact, engineers worked with what was available because no suitable alternatives existed. 

Fortunately, new, advanced sealing epoxy compounds were developed that provided exciting opportunities for vacuum feedthrough manufacturers. These new materials opened the door for a more efficient and flexible feedthrough design.

Today's epoxy vacuum feedthroughs have nearly the same application reach as their glass and ceramic cousins in low to medium temperatures. Epoxy vacuum feedthroughs provide an outstanding alternative in terms of customization and versatility for designers and engineers. Shapes, angles, and curves are not a concern. It is possible to use virtually any form of shielded wire or cable. Production in minimal amounts for prototyping and R&D, custom epoxy vacuum feedthroughs can be easily supplied. Modern epoxy feedthroughs sustain a vacuum of up to 10-8 Torr, with continuous temperatures of up to 200 ° C (intermittent 300 ° C), and therefore meet the outgassing criterion of NASA of < 1.0 percent Total Mass Loss (TML). Liquid epoxy's ability to flow and fill spaces thoroughly provides an important additional benefit. In most applications, epoxy feedthrough may be used where a glass-to-metal or ceramic feedthrough is used-the; only notable exceptions are in extremely high-temperature applications or where organic compounds are not authorized. 

Within the restricted world of glass-to-metal and ceramic-to-metal feedthroughs, designers and engineers no longer have to wonder. Epoxy feedthroughs are a modern, exciting player in the game, making them a very enticing option with lower cost, fast prototyping, and more versatile design capability.

High Temperature 16 Pair Type J Thermocouple Feedthrough

16 Pair, High Temp Type J Thermocouple Feedthrough

BACKGROUND

A 3D Printer company specializing in Aerospace parts provided BCE a challenge in creating a High Temperature Feedthrough for their new composite 3D printer.  The 3-D composite company needed a high enough temperature in the sealed area with a vacuum chamber being essential in printing aircraft components.  They had difficulties integrating their existing thermocouple design into their expanded chamber with an off the shelf feedthrough.

SCOPE

The 16 (32-wire) Pair Thermocouple feedthrough needed to satisfy the following:

• Operating temperatures between -25 C to 300 C
• Low vacuum leak rate of 10^-9 ATM-CC/S or better
• Able to withstand a 450 C Bake-out temperature
• Type J thermocouples (customer preference) with ring terminations 
• Fiberglass lead wires to withstand the high temperature

OUTCOME

BCE successfully designed a Thermocouple Feedthrough with a type J T/C extension wire so that the customer could integrate the component with ease into their 3D Printer. The High Temperature Feedthrough went through extensive pressure and temperature cycling before being shipped.  One final helium leak check was made and a polarity verification for all connectors was done too.

Fiber Optic Feedthrough

A company contacted BCE to design a fiber optic feedthrough for their new assembly. They required (4) x 100 inch single mode coupler fibers to reach a narrow area within their assembly. The customer had a difficult time finding a compatible solution due to the specific thread type and the long fiber length so they approached BCE to create a custom feedthrough. Due to the sensitive nature of fiber optic cable, a BCE Epoxy Feedthrough was the optimal solution.

REQUIREMENTS:

• 4x single mode Acrylate coated fibers
• ¾”-16 threaded 316 SS fitting
• Helium leak test: 5 x 10-8 atm-cc/s or better
• Temperature range: 0°C - 65° C
• Long lead length ~100”

Click for larger view.

OUTCOME

The small outer diameter (245 µm with an 8 µm core) of the fibers and the long length, required the addition of Hytrel furcation tubing to prevent breakage by reducing the bend radius. This created a robust feedthrough to withstand a wide range of vacuum and temperature conditions. The fiber optic feedthrough exceeded expectations and achieved a 10 x 10-10 atm cc/s helium leak rate.

High Amperage Electrical Feedthrough

BACKGROUND

A customer involved in lithium ion research approached BCE in need of a high amperage feedthrough that also met their packaging (size) requirements.

While the customer had no problem finding high amperage feedthroughs, or feedthroughs that met their size requirement, they could not find an acceptable electrical feedthrough that satisfied both.

BCE is known for designing to customer specifications, allowing engineers the freedom to build their systems according to their plans, and not having to make design sacrifices because of hardware limitations. This application is an excellent example of BCE's capability.

OUTCOME

After a comprehensive application review with the customer, BCE went to work. Designs were completed in a few days and prototypes were completed in a few weeks. After preliminary tests and designs, a final prototype High Amperage Feedthrough was delivered for customer evaluation.

After thorough testing, the customer agreed that the application requirement was precisely met and the feedthrough functioned perfectly.

With the feedthrough now in production, all customer specified tests are performed prior to shipping and completed at BCE. Production and testing are controlled by a jointly developed standard operating procedure (SOP).

While this feedthrough was designed for a single, specific use, the underlying construction is designed to easily accommodate changes. Nearly every feature is customizable, including conductor type and gauge, flange type and size, component materials, and electrical rating.

The BCE High Amperage Feedthrough needed to satisfy these customer criteria:

• 150 Amp 30 Volt
• Custom KF50 Flange 
• Vacuum rating: 10-6 ATM-cc/s 
• Feedthrough Seal Temp: -10 C to 60 C
• Able to withstand the weight of the heavy gauge wire
• ALL TESTS PERFORMED AT ROOM TEMPERATURE

OEM Equipment Manufacturers: Look Toward the Experienced Sales Engineer for Project Success

Original Equipment Manufacturers (OEMs) who work closely with vendor sales engineers in the design of assembly components (such as electric heating elements and vacuum feedthroughs) gain a valuable competitive advantage. By understanding what these professionals have to offer, and taking advantage of their skills, OEM designers end up with better project outcomes.

Sales engineers are a readily available resource of application knowledge. Unlike information pulled from the Internet, sales engineers possess real-time product information. They are also exposed to many different product applications and are a wealth of tacit knowledge. All readily available for sharing with their customers.

OEM design engineers often find themselves sailing in uncharted waters. In the application of electric heaters or feedthroughs for instance, designers don't always have a full grasp of heater or feedthrough design constraints. When these situations occur, the heater sales person provides a real benefit in teaching and advising the designer what is possible.  Additionally, many sales engineers have access to unpublished product and application information, which can be hugely important when attempting to build a leading edge product.

Of course any solutions proposed are likely to be based upon the products sold by the representative, but the best sales people will share the virtues of their products openly and honestly. The best sales engineers will even admit when they lack the product or experience to solve the problem, but even in this situation, you can be sure their perspective will still be of value. The goal is to build a long-term, trusting relationship - one of value to both parties. Sales engineers are in the business of dealing with people and making the important connections between customers and manufacturers. They make it their business to know what’s going on with products, companies and industries.

As an engineer or purchasing professional responsible for the design and manufacture of OEM equipment, know that working closely with a vendor sales engineer will save you precious time and greatly improve the likelihood of successful project outcomes. Their success, and your success, go hand-in-hand.

Understanding Vacuum

At sea level, the earth's atmosphere exerts a standard pressure upon us of 14.7 pounds per square inch absolute (PSIA), or 29.92" of mercury (Hg), or 760 mm of mercury (Torr). All of these values refer to "standard atmosphere" which is measured at sea level.

Vacuum is a term used to describe an area, zone, or compartment containing less pressure than atmospheric pressure.

Vacuum is measured in inches of mercury (Hg) in the United States. There are two different scales to measure vacuum.

One scale is referred to as "inches of mercury gauge vacuum" ("HgV), where the measuring range starts at 0 inches of mercury (atmospheric pressure) and goes up to 29.92 inches of mercury, known as perfect vacuum (not achievable on Earth).

The alternative scale is "inches of mercury absolute vacuum" ("HgA), which reverses the "HgV scale, having it instead read 29.92 inches of mercury at atmospheric pressure and 0 inches of mercury at perfect vacuum.

Here's an example of the relationship between inches of mercury gauge and inches of mercury absolute:

24 inches of Hg gauge = 5.92 inches of mercury absolute.
Calculation: 29.92 - 24 = 5.92

It is very important to  determine what scale you are using, meaning gauge or absolute. A misunderstanding can result in large errors.

The unit "Torr" is used when working in higher vacuum ranges (low absolute pressure). 1 Torr equals 1 millimeter (mm) of mercury in absolute pressure.

Considering one linear inch equals 25.4 mm, and atmospheric pressure (at sea level) is 29.92 inches of mercury, then using the equation 29.92 inches x 25.4 mm = 760 Torr. 760 Torr is 0 vacuum, while 0 Torr is perfect vacuum.
