Vibration Testing is performed to validate the reliability, performance and structural integrity of a device during its transportation and useful life, avoiding life failure in space. Vibration Testing mimics the conditions such as the one during a rocket launch. Some devices have mechanical parts that may be sensitive to testing and therefore to have a malfunction in its final application.

This paper will present the assessment of automotive qualified components for Space applications being performed in the frame of ESA Contract 4000126343/19/NL/hh. The proposed work to be performed includes a full thermomechanical and endurance evaluation (2000h life test, 500 cycles -55ºC to +125ºC thermal cycling, HAST or THB) along with constructional analysis and measurements of Tg (glass transition temperature) and outgassing. These tests will be done on three different lots separated by years of lot date codes on three selected AEC-Q candidates (total 9 lots). This testing will allow to confirm manufacturing stability (die mask, assembly techniques, moulding material, etc….) and process variability over time. The three candidates are selected from non-radiation sensitive devices of an “AEC Space PPL” List already compiled from the comparison of what is offered as AEC qualified (AEC QPL list with >200K items) and what is more demanded for Space (Space PPL list from ESCC QPL/QML/PPL, NASA NPSL/GSFC PPL, etc.. with 1500 items).

Product durability and accelerated life cycle testing are all methods of determining the reliability of a product before release. By subjecting the capacitor to elevated conditions far beyond its normal operational ranges, we seek to discover any defects or points of failure to better inform customers about the limitations of the unit.

MLCC capacitors are dominating today’s capacitor market enabling high grade of electronics miniaturization. The continuous downsizing and use of higher and higher dielectric constant materials for MLCC class II capacitors has however resulted in worsening of some electrical parameters stability such as capacitance drop at operating conditions.

In the scope of the GSTP program, Fraunhofer INT will perform radiation tests and functional verification tests on COTS components under contract of the European Space Agency. It’s key points are twofold: First it’s to identify and test available COTS components whose functionality or properties would greatly benefit the space community. This will make use of the so-called spin-in approach.
