Abstract
Abstract A machine for attaching connecting wires to connection points of a semiconductor component and to connection points of a housing which is to accommodate the semiconductor component is comprised of a wire guide which is vertically adjustable with respect to the semiconductor component and to the housing and through which a wire is fed and a support which is adjustable in two dimensions parallel to the plane of a semiconductor component and which carries either the housing with the semiconductor component or the wire guide. The machine also includes a programme carrier which may be advanced step by step into successive detent positions and which have guide members which cooperate with a complementary guide member on a driver connected to an adjustable support and are so arranged that in each detent position a guide member of the programme carrier is disposed from a stationary reference point a distance which in magnitude and direction is in a predetermined relationship to the distance of a connection point from a reference point of the housing of the semiconductor component. The guide members of the programme carrier are conical bores, the driver is a rocker pivotally mounted on the adjustable support and the guide member of the driver is a guide cone. Because of the cooperation of the guide members on the programme carrier and the guide member on the driver, the adjustable support is automatically brought into the positions in which the guide lies exactly above a connection point of the housing or of the semiconductor component.
