Testing HI-REL & SpaceCOTS® parts

 

The quality of High Reliable (Hi-Rel) and selected commercial-off-the-shelf (COTS) parts is the fundamental basis in aerospace engineering performance.
Our qualified team performs environmental test for Hi-Rel and so called SpaceCOTS® parts, EEE (Electrical, Electronic and Electromechanical) components and assembly systems delivering ad-hoc engineering solutions and assurance tests to comply with the demanding requirements of space projects.

1. Radiation testing

Based on more than 30 years experience in aeronautics and space programs, ASTRIONICS has developed an innovative state-of-the-art radiation test. These tests are important in space technology but also in  terrestrial applications, e.g. nuclear medicine and industry, material science, high energy physics, etc..

Radioactive environments may affect the reliability of EEE parts and systems by degrading some electrical parameters of the device leading in a worst case scenario to an irreversible malfunction.

Two radiation effects are of main importance for EEE parts:
– Total Ionizing Dose (TID) gamma radiation (accumulative radiation process), and
– Single Event Effects (SEE) by using energetic protons or heavy ions.

Spectrum ARC has the experience to perform the tests according to MIL-Specs. or ESA standard for radiation, i.e. for TID the ESCC 22900 and for SEE the ESCC 25100, or project specific. All radiation tests services include sample preparation, programming, test board development and final reporting.

 

2. Thermal-Vacuum testing

Space EEE parts and boards have to work under extreme thermal and vacuum conditions. Radical temperature changes over several tens of degrees in few minutes stress the hardware and can reduce the component lifetime considerably.
ASTRIONICS performs destructive and non-destructive (cycling) tests using biasing or not and according to the project requirements.

3. Mechanical testing

Satellite subsystems and components have to resist different mechanical forces especially during launch. This situation can be simulated effectively by performing vibration and mechanical shock tests. Both tests are prepared and executed by ASTRIONICS following the project specifications.
