Abstract: In a process for bonding simultaneously a series of juxtaposed connecting terminals of an electric component to a connecting tag block, one tag per terminal, by the application of a bonding tool to the respectively superposed tags and terminals, the bonding tool is applied to the superposed tags and terminals through a sheet of ductile, heat conducting material. This sheet is made preferably in the form of a tape moving in synchronism with a tape carrying blocks of the tags. The two tapes are guided and driven in guide blocks placed each side of a work station carrying the components to be bonding. The tape of ductile material can serve as a protective strip for the tape equipped with the bonded components.
