Our history

In 1918, MICAFIL AG was founded by Fitz Aebi and S.A. Atelier de Sécheron (SAAS). In 1920, Brown Boveri & Cie. (BBC) acquired the majority of shares. 1998 MICAFIL became part of ABB.


The name «Micafil» derives from two important materials in the field of electronics: «Mica» stands for phyllosilicates and «fil» means wire.


However, «Micafil» is more than the name of an acquired company, it is a registered product brand name, which stands for quality worldwide.
