High Altitude Vacuum Testing of Electrical Connectors and Components

high altitude test chamber of electrical components

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.

Altitude Simulation Systems
Altitude simulation systems are devices that simulate a certain altitude equivalent by controlling the vacuum inside a vacuum chamber. Altitude is a function of absolute pressure, therefore if a certain pressure is accomplished inside a vacuum chamber, a specific altitude can be simulated from the set pressure. Altitude simulation systems can be configured to not only hold a certain pressure, a complete pressure vs time profile can be programmed to be run. Furthermore, pressure vs time recipes can be loaded and run based on test requirements.
Rotary Vacuum Feedthroughs
Rotary Vacuum Feedthroughs are devices that will enable you to physically rotate a specimen inside the vacuum chamber while vacuum present without decreasing the vacuum.
Our Work: Modified 14 inch Cube Vacuum Chamber for Degassing
This custom job was a modification to our standard acrylic vacuum chambers. When it comes to working with the Us Military, they want all specs to be met 110% and they want it yesterday. The military does not mess around which is why they came to us since we know how important it is to meet specs and ship fast.
Related Articles: Force Decay Leak Testing
Force Decay Leak Testing is a very popular quantitative leak testing method used to quality test package and product integrity due to its ability to detect small leaks which cannot be seen through visual inspection. In this method, the test specimen is internally inflated by either internal pressurization or vacuum force. The inflated test specimen will, in turn, apply a force on a pressure transducer. Finally, the change in force applied by the inflated specimen over a specified time is observed.
