Test Laboratory

Design Verifcation 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. 

Electrical Tests

Innovative measuring and testing equipment is used to measure all functionally relevant electrical values. These reflect the highest performance ranges.

  • Electrical voltage up to 30 KV
  • High frequency measurements up to 110 GHz
  • Passive intermodulation in all common frequency ranges
  • Electrical capacity up to 370 mF
  • Electrical inductance up to 750 kH
  • Magnetic flux density up to 1999 mT
  • Vector network analysis up to 70 GHz
  • High current tests up to 3,600 A

Analytical Methods

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.

The amount of dirt on the surface of a component defines the technical cleanliness. To determine this the residual dirt weight as well as the number, size and composition of the dirt particles are determined.

Further Analytical Methods for Quality Assurance:

  • Microsection preparation
  • Differential Scanning Calorimetry
  • Raman Microscopy
  • Wettability soldering scale
  • Laser Scanning Microscopy

Environmental Audits

The following aspects are tested using various innovative methods:

  • Vibration resistance
  • Climatic stress
  • Corrosion phenomena
  • Tightness

Temperature Cycle Test

Our robot-controlled facilities carry out automated temperature change testing on materials and product construction regarding performance under extreme loads.

Mechanical Test Methods

Different mechanical forces are used in the field of electrical connection technology: insertion and separation forces, cable retention forces, normal contact forces or bending moments and torques. During testing these are simulated with the aid of force test benches. Forces up to 250 kN and torques up to 100 Nm can be tested in highest resolution.

Further Mechanical Methods for Quality Assurance:

  • Flexural and drop test
  • Mating frequency
  • Frequency of bending cycles
  • Rotation change frequency
