  • Method for connecting contact surfaces of electrical component blanks and device therefor
    Patent number: 6460246
    Abstract: In order to connect contact surfaces of electric component blanks for layer resistors to at least two elongated, metallic connection leads, elongated, slot-shaped openings are made, e.g., by etching, in a continuous metal sheet to manufacture a connection lead blank. The openings border on later connection leads of the connection blank and cross-struts yet to be removed. In a second step, the connection lead blank is brought into a cassette and seized, whereby one of the cross-struts projects out of the cassette and is separated in a third step, such that the free ends of the parallel-running connection leads project out of the cassette. In a fourth step, the cassette is brought into a bonding or welding device, so that the free ends of the connection leads cover the contact surfaces of a component blank or a multi-component blank and are connected together by a bonding or welding operation. In case a multi-component blank (multi-unit plate) is used, it is then separated into individual components.
