About testedge

testedge GmbH & Co. KG is a partner specializing in test technology for electronics manufacturing, headquartered in Stuhr near Bremen with a second location in Wolframs-Eschenbach. The company was formed on 01.09.2024 from the merger of TAP Automatisierte Prüftechnik GmbH & Co. KG and KTT Testengineering GmbH, which had been active in fixture building since 1993. testedge develops in-circuit and function test applications on modern board testers (Teradyne TestStation LH, SPEA 3030), boundary scan test concepts on GÖPEL JULIET systems, and custom hardware and software for function tests. This includes on-board programming of assemblies, software development in languages such as C++, C#, LabView, Teststand and TECAP, as well as the construction of test fixtures including wiring, supplementary electronics and in-house CNC machining. Customers come from electronics manufacturing, automotive, aviation and medical technology. Quality management is certified to DIN EN ISO 9001; the team of more than 30 accompanies projects from design through to commissioning.
