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.

Vacuum Degassing Systems
Vacuum Degassing Systems enable you to remove trapped gas inside your liquids - generally, epoxies. Degassing is a vital part of any two part or more mixing process, this includes but is not limited to epoxy, pharmaceutical mixing, potting, recipe creation. A vacuum degassing system consists of a vacuum pump, connection hardware (includes filters and traps) and a vacuum chamber.
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: Chamber for Vacuum Extrusion System
This is a custom acrylic vacuum chamber build for a high volume manufacturer of parts which are fabricated using vacuum extrusion techniques. The challenge was to build a vacuum chamber system which mated on two perpendicular surfaces; on the bottom and on the rear of the chamber. This was accomplished by incorporating a double gasket mechanism on the bottom and incorporating a clamping mechanism on the rear.

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.
