Failure analysis

Other services

ARENIUS laboratory realises other qualification tests such as abrasion test, scratch test, traction and tensile test, fluid contamination test (automotive and industrial fluids, synthetic sweat...)
Among these tests, our laboratory realise also ESD (Electrostatic discharges) until 15 kV, and electrical safety test. Our laboratory performs also failure analysis by micrographic section and SEM (Scanning Electron Microscopy) for your quality trouble analysis and investigations (soldering shape, alloy quality...)
We have committed ourselves to a quality accreditation processes (COFRAC, CIL, PTP). Our laboratory is a member of ASTE (Association pour le développement des sciences et techniques de l’environnement) association.

Failure analysis

As part as your analyses or investigations in order to establish failure mechanisms and modes (contamination, corrosion, electro-migration, whiskers, soldering failures…) we realize non destructive or destructive analysis according to your requirements.
- Binocular observation
- Wetting analysis
- Chemical package opening
- Micro sectioning
- EDX material analysis (energy-dispersive X-ray spectroscopy)
- SEM observation (Scanning Electron Microscopy)
- Layer and inter-metallic thicknesses measurements

Mechanical design office

Vibrations tests mechanical interfaces design is a leading step for reliable tests results, fixtures must ensure physical strength transmissibility without increasing tests severity because of resonance frequencies. Our laboratory can manage complex mechanical interfaces design for your vibrations tests. Services include drawings design, modal analysis, and fixtures manufacturing with qualified subcontractors.

Our mechanical design office develop also mechanical endurance benches according to your specifications tests. Our philosophy is to develop less expensive solutions particularly when only one qualification test is requested. Our service include control and measurements software programming (Labview MMI), parts benches industrials drawings, and benches conception.

Intellectual engineering

With 20 years of experience our laboratory can support you during the products qualification test plans (QTP) writing. At the end of consultation step and specifications analysis (life profile, product mission) we define and write QTP: tests groups, tests severities, tests durations…
