Test Laboratory

Design Verification and Reliability Testing

Rosenberger Always Delivers when it Comes to Products of the Highest Quality and Maximum Precision

The ability to achieve such a high standard of product excellence is down to extensive testing and validation which is performed at the company’s Test Laboratory. Here simulation techniques carried out beforehand in Research and Development are put into practice enabling highly effective validation of the properties functionality and design of all products.

The Test Laboratory’s state-of-the-art equipment and highly trained personnel are able to carry out environmental simulations, mechanical and electrical tests as well as optical analyses. The testing process is innovative and solution-oriented, delivering fast decisions based on valid results and extensive documentation.

Analytical Methods

Material and Structural Analysis Using EDX/REM X-Ray/Computer Tomography Thermography Resistance to Soldering Heat (Reflow)

In the course of up to 300,000-fold magnification in combination with an energy-dispersive X-ray analysis the system provides information about the local occurrence of chemical elements.

Deviations from the geometric ideal of the product are analyzed using high-resolution X-ray equipment and computer tomography - the 2 and 3D images are then compared with CAD data.

This non-contact method for temperature measurement on power loaded connectors shows local overheating in addition to temperature distribution. The system used allows a thermal resolution of 0.08 K.

For connectors soldered directly onto a circuit board, not only solderability but also solder heat resistance is a decisive quality consideration. In addition to the choice of material a customer prerequisite for ensuring reliable processability is a qualitatively perfect coating.
