The semiconductor industry is increasingly important. One key stage in the production of chips is testing the integrated circuits on the wafer, a process called wafer probing. ERS electronic GmbH was founded 50 years ago to develop thermal chucks, which hold the wafer in place while allowing for thermal testing. It was a revolutionary development at the time, and while this kind of testing is now relatively mainstream, the company is still the global market leader in thermal chucks. ERS electronic GmbH is headquartered in Germering, near Munich, and offers both standard and customized solutions.
