Testing & Inspection

Our specialization

assembly validation

Temperature shock testing

DMS application and strain measurement

Testing services from a specialist: we are specialized as a testing laboratory for the simulation of specific environmental conditions and the monitoring of the influences of these conditions on electronic assemblies. We offer the following services in our test lab and at your site as contract testing.

Thermal shock chamber
Electronic components are tested under rapidly changing environmental conditions in the thermal shock chamber.
Real environmental conditions in the climate chamber
Long-term tests under real environmental conditions in the climate chamber.
X-ray analysis and CT analysis of electrical assemblies.
Qualification of printed circuit boards at TEPROSA
Qualification of printed circuit boards at TEPROSA.
Examination of a printed circuit board using x-ray-analysis
Examination of a printed circuit board using x-ray-analysis.

Assembly validation (complete validation)

We perform environmental simulation tests and climate simulations for validation and qualification of electromechanical assemblies according to customer standard or specification requirements.

In doing so, any form of chemical, physical or other environmental impact on the product can be simulated by combining various individual tests. On request, we can implement electrical condition monitoring of the test items during the test according to your specifications.

Temperature shock test (single test)

In a temperature shock test, test specimens are repeatedly subjected to defined temperature changes (so-called temperature shocks) in order to test the effects of the temperature changes on the test specimens.

TEPROSA offers a variety of specific tests we thermal shock (according to DIN EN 60068-2-14), cold (according to DIN EN 60068-2-1) or heat (according to DIN EN 60068-2-2).

DMS application and strain measurement

In a strain measurement (also strain gage application or strain gage strain measurement), deformations caused by an elongation of the material are measured and made visible. This is also referred to as experimental stress analysis.

Damage & Component Analysis

In our test laboratory, we perform X-ray, SEM and EDX analyses, among others, to help you resolve damage and field failures. Following the damage & component analysis, we are also available to assist you in any corrective loop of your electronic assembly and can handle the complete rework/redesign if desired.

Our capabilities:

  • X-ray testing
  • Gauge strain measurement
  • CT X-ray analysis
  • X-ray fluorescence
  • REM and EDX analyses
  • Graph analysis
  • Eveness and roughness measurement
  • Shear and pull tests
  • Contamination testing
  • Tightness testing
  • SIR test
  • Electrical safety testing (dielectric strength, insulation testing)


Even before the damage has occurred in the field, we can help you troubleshoot your circuit.
