High Altitude Vacuum Testing of Electrical Connectors and Components

high altitude test chamber of electrical components
Rear view of the Custom Vacuum Extrusion Chamber
This was an interesting project where one of our customers needed to test wires up to 44 inches long within a high altitude simulation environment. In addition to testing wires, several other electric connectors required altitude testing as well. The altitude requirements were 100,000 feet (30.510 km) which corresponds to 8.36 Torr - a piece of cake when it comes to the vacuum requirements of our chambers.

We would like to take a moment and bash our competitors on this one and point out where they went wrong: Our competitors have sales people and not engineers communicate with their customers when it comes to understanding customers design requirements. This leads to suggesting over-engineered solutions of humongous projects, prices, and lead times. When this customers came to us to, our question to them was simple: "What exactly are you trying to accomplish and what are the exact dimensions of the part you were testing?" This enabled us suggest a chamber which was 52 inch long and about 6 inch in diameter with a custom designed lid. Our quote blew our competitors away because 1. their sales staff had no idea what the customers goals were and 2. they were over-engineering, hence overcomplicating a simple problem.

What you see here is a:

1. custom vacuum chamber which allows for plenty of space for electronic wires and widgets to be tested at high altitude.

2. A custom design vacuum chamber Lid which allows for flexible electronic connector changes enabling fast and reliable high altitude electronic equipment testing.

Helium Leak Testing Systems
Helium Leak Testing Systems are instruments which detect leaks in specimen by detecting present of helium. Helium is used as a tracer gas to detect and quantify a leak. For example, a test specimen is filled with helium and placed into a test chamber, a vacuum is pulled and a helium mass spectrometer is connected to the test chamber. If helium is detected, it is due to the fact that it has escaped from the specimen through a leak path. Helium Leak Testing is a qualitative and quantitative method of detecting product leaks.
Micro-D Vacuum Feedthroughs
Micro D Vacuum Feedthroughs are Micro D connectors rated for vacuum and are generally installed on the vacuum chamber wall. You can then connect from the outside to the inside of your chamber.
Our Work: Vacuum Testing of Lithium Ion Batteries, Thin Film, Fuel Cells, Supercapacitors, and Nano materials
This vacuum chamber is a modification to our basic acrylic vacuum chamber 12 inch, removable lid model; except that our customer requested additional ports and electrical feed-through for testing of electrical equipment under vacuum. You know, I wish we would have asked them for more details on what they were doing with this chamber; their short and concise answer was that they were using our chamber to perform scientific work on the subjects of: lithium ion batteries, thin films, fuel cells, super-capacitors, and nano-materials testing in a vacuum environment.

In the article we are going to cover rotary vane vacuum pumps. We will touch upon how they work, what they are used for, when to utilize a rotary vane vacuum pump, its advantages and disadvantages. Perhaps you have noticed that rotary vane vacuum pumps come in all shapes and sizes. On one website, the vacuum pump is less than a $100; on another website you see a vacuum pump quotes at $10,000. I would imagine that you immediately ask yourself what the deal here is.
