1,273,791. Component assemblies. COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS C.I.T. ALCATEL. 28 July, 1969 [2 Aug., 1968], No. 37846/69. Heading H1R. A method of manufacturing plug-in support cards for wired electronic circuits having the circuit elements disposed on one face card and the circuit wiring on the other, comprises drawing the positions of the wires, components and terminals full size on a transparent label, duplicating the drawn label, sticking one label drawn-side up on one face of the card and the other label drawn-side down on the other face such that the drawings align point for point through the board, perforating the board at terminal positions and inserting eyelets for terminals to which the wires and circuit elements are soldered. The drawings can include the positions and values or identification marks of the circuit elements and can be drawn on paper and reproduced as necessary for cards to be similarly manufactured. Such cards may be connected together in slideways to form composite circuits. |
