Who we are

Founded in 1977, we began with the production of thick-film hybrid circuits. Having grown with what was, at the time, still a young technology, Leuze electronic assembly now specialises in high-quality production technologies for electronic components. We use the most modern technologies in our production facilities. Each work step, from the receipt of the order to delivery, is monitored. Even small lot sizes are produced economically.
