Our history


The industrial activities and company history of the ASSMANN family is already starting in the 18th century. ASSMANN & Söhne did produce at that time metal buttons for the clothing industry and as well medal decorations for the military. Later on in the 20th century ASSMANN & Söhne became famous for being one of the pioneers for heat sink technology.

Parallel to the company ASSMANN & Söhne another company named ASSMANN KG had been established in 1969 and Dieter Assmann started in this company his activities around the development and production of IC sockets and IDC connectors for flat cable applications. In the 80's Dieter Assmann combined and controlled both product ranges, the heat sink and the connectors, in the company ASSMANN GmbH, which became later the ASSMANN Electronic GmbH. During these times, another product segment has been developed, so called computer- and network peripherals. This business showed a tremendous growth under the leadership of the sons.

Due to this development, in 2005, the management functions for these product segments, heat sinks and connectors, had been handed over to new share holders, which became as well the managing directors, Mr. Weidenhammer and Mr. Walter, which combined these activities within the new established ASSMANN WSW components group under shareholder-ship of the ASSMANN GmbH & Co. KG.

In 2022 this shareholding is no longer applicable, due to the acquisition of the ASSMANN WSW Group by the BCS Group (Braun Connectivity Solutions Group GmbH). The managing directors Mr. Weidenhammer and Mr. Walter keep their positions as managing directors of the ASSMANN WSW Group. Both have also been appointed as members of the BCS Group executive board. With the acquisition of the ASSMANN WSW Group, the BCS Group positions itself more broadly. As Dieter Braun is still a well-known manufacturer and supplier for automotive cable assemblies, the BCS Group GmbH want to enlarge their turnover through the ASSMANN WSW Group at the industrial market.


Continuous quality control and following the Zero Defect Strategy the ASSMANN WSW group has been set as main target.

Qualifications according to DIN ISO 9001:2008 and DIN ISO 14001:2005 have been first important steps on this way.

Prerequisite is to work only with certified and / or audited partners. To reach the qualification according to QS 9000 and ISO TS 16949 for the manufacturing plants is another target. At ASSMANN WSW QUALITY is written in BIG letters.
