The Company History

SMT Maschinen- und Vertriebs GmbH & Co. KG is one of the market leaders in production technology for electronic assemblies. At our headquarters in Wertheim, we have been developing and producing soldering systems and heat transfer machines which are used worldwide in the electronics industry for over 35 years.

With branches in China and Mexico, SMT Wertheim has become global. The company holds several patents and has developed numerous innovative processes that are now part of the technological standard.


On February 13th, 1987, company founder Hans-Günter Ulzhöfer registered SMT Maschinen- und Vertriebs GmbH & Co. KG in the commercial register.
