Precision for more insightMeasurement and testing

With two – also combinable – tactile methods, we offer measurement and testing work. On the one hand, as a standard procedure, for the geometric measuring of components to determine the shape, position and dimensions of elements; on the other, to determine the surface finish for precise information on the functional surfaces of workpieces. In this way, manufacturing qualities and discrepancies can be reliably determined. This service is particularly of interest to customers in optics and optoelectronics, the coating industry, the medical technology and semiconductor technology sectors, and in research and development.

Geometrical measurement

Two basic procedures are used to measure and determine the quality of workpieces: On the one hand, the tactile (geometrical) measurement of components: In this standard measuring method, the shape, position and dimensions of elements are determined by systematically scanning the workpiece surface with touch sensors. On the other hand, determination of the surface finish delivers precise information on the functional surfaces of workpieces. Both allow reliable conclusions to be drawn about production quality and discrepancies. To determine the surface finish, the stylus method is used to give the surface profile of workpieces with a diameter of even only 5 mm by means of automated scanning.

Resistivity measurement

The electrical resistivity and conduction type of semiconductors, such as silicon, determine key properties for the functioning of components. A common method for determining resistivity is the four-point probe direct-current method. This permits the resistivity of a workpiece to be precisely determined – the results are decisive for the assessment of the respective properties.
