The testing technologies

To ensure top quality, the sub-assemblies manufactured by Liebherr-Elektronik GmbH undergo severe tests.

In serial production, the highest test level is standard for printed circuit boards and appliances. Depending on the requirements of the customers, the robustness and longevity of the sub-assemblies is also tested in special environment tests such as temperature and vibration tests.
