Abstract

1,142,627. Printed circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 27 May, 1966 [1 June, 1965], No. 23947/66. Heading H1R. In a printed circuit board 1 provided with lines of local weakness, such as perforations 7, to facilitate the division of the board into separate parts 3 ... 6, the printed circuitry on the separate parts is connected together by thin printed wires 8 which cross the rupture lines to form a functionally unitary arrangement, and enlarged, preferably circular, contact areas 9 are provided at each end of each wire 8 on either side of a rupture line. Associated components (not shown) are mounted on the board 1 and the entire circuit is tested before the board is divided. After division, and before or after the mounting of the parts 3 ... 6 in an assembly, connections broken by the severing of wires 8 are restored by bonding conductors between the relevant contact areas 9, which may be apertured. The board 1 is formed by conventional techniques from a metal-clad paper-based insulating laminate and may be double-sided. Instead of lines of perforations, the rupture lines may be delineated by grooves in the boards; and the wires 8 may be weakened at the line or rupture, by scratching or nicking. Figs. 3, 4 (not shown) depict a printed circuit board in which a portion (16) to be removed is defined by a slot (13) and a single line of perforations (7); after division, the two parts (16, 17) of the board are mounted perpendicular to one another on a radio chassis, and are mutually connected by fly leads (12).
