Abstract

A bonding head for connecting the electrically conductive leads of a tape cable or the like to other electrical conductors. The bonding head, which applies heat and pressure to the electrical conductors and leads to bond them together, is an elongated member comprised of a material having high mechanical strength but low thermal conductivity which contains a conduit comprised of a material having low mechanical strength but high thermal conductivity. A heating element inserted in the conduit supplies heat to the conduit and bonding head. This arrangement provides a bonding head having a high mechanical strength and hence structural failure and deformation of the bonding head is reduced.
