Abstract: A method and system to produce card modules by assembling and soldering components on a printed circuit board, characterized by retrieving specific printed circuit board-type from a printed circuit board storage having several types in response to a command signal, reading an identification code on the printed circuit board to obtain information concerning the board and then in response to this information, conveying the circuit board through selective processing stations for assembling components on the circuit board, through-stations for soldering the components on the circuit board to form an electronic card module and then through-stations for testing the card module in response to information obtained during reading. The testing station can also include one or more stations for performing the steps of fault-locating and for repairing located faults as necessary.

Abstract: An installation for manually assemblying electrical and electronic components on a printed circuit board using a display device for optically identifying the respective assembly positions of the component on the board, at least one magazine with a removable position for supplying the required component and an arithmetic unit for controlling the display device and selection of the particular magazine characterized by the magazine being designed to carry all components for a large number of different printed circuit boards and an identification device which is connected to the arithmetic unit to identify the particular circuit board which is being supplied, sending a signal to the arithmetic unit to identify the board so that the arithmetic unit provides the necessary assembly program.
