Abstract

1536471 Scoring STANDARD TELEPHONES & CABLES Ltd 2 Jan 1976 52/76 Heading B6J [Also in Division H1] A printed circuit board 1, (Fig. 1) e.g. for colour TV has, e.g. 54 individual circuits 2 printed thereon; a peripheral margin 3 surrounding the circuitry with locating dowel holes 4. Score lines 55<SP>1</SP> are cut by a planing head out of both sides of the board and holes 7 are pierced in the copper of each circuit to admit component leads. Thereafter the board is broken along AA, BB into sub-boards 6 of 18 circuits each, which may be further subdivided. The machine for scoring the lines of subdivision comprises (Fig. 3) a base 23 on which travels a platform 24 with dowels 25 on circuit plate 30 to engage the locating holes 4 of the circuit board. Platform 24 runs on linear ball bearing shafts 26 at each side of the base and is reciprocated by hydraulic ram 27. Circuit plate 30 retains the circuit board between it and platform 24, and is slotted longitudinally at 31 to define grooves 5; being replaceable by further circuit plate defining grooves 5<SP>1</SP>. Heads 32 of planing tool 33 enter the slots and the heads of another such tool are mounted below platform 27; the tools being located by posts 38 and the lower heads being applied through rectangular aperture 34. Cross beam 35 with rollers 35<SP>1</SP> press the circuit board against circuit plate 30 during its travel. Slots 4a at one edge of the circuit board engage dowels 37 of a slot 36 into which the leading edge of the board is entered prior to engagement of the circuit plate 30 and the commencement of reciprocating planing.
