Life Expectancy of INGUN Test Probes

To determine the life-expectancy of Test Probes, INGUN continuously carries out fatigue tests under laboratory conditions using computer-controlled fully automatic fatigue test stations. Here the behaviour of important parameters such as contact resistance or the spring force during the life of a Test Probe can be observed and defined. The resulting knowledge is taken into consideration in the development. This guarantees state of the art high-quality standards.

The life-expectancy of Test Probes is a function of various parameters such as spring force, axial loading, current loading as well as external influences such as contamination and temperature. INGUN has avoided printing out here any diagrams and tables of tests, which were carried out under laboratory conditions, because such results would only give the user a false impression. This is because the above stated influences are non-calculable factors, which can have a decisive influence on the life-expectancy of a Test Probe. Under laboratory conditions it is possible that some Test Probes series will do well over 1 million cycles, but the actual period of usage could well be much less because, for example, the strong general wear of the Test Probe leads especially to wear of the contacting zone - resulting in a drastic increase of the contact resistance values.
