Veroboard-Production-Custom Design Circuit
Board Electronic Pcb
Production of the proposed new product, Veroboard, was undertaken by the VPE machine tool department.
Bought-in sheets of 1.6 mm (0.2 in) copper-clad SRBP printed circuit material were cut to give 122 mm x 456 mm (4.8 in x 18 in) size boards with the individual boards then being machined to form the final product according to the original Veroboard specification. A multiple milling cutter tool, which comprised a bank of side-and-face cutters with suitably shaped cutting teeth, was fabricated - to be used in removing part of the bonded copper on each board leaving 21 conductive strips. For a second operation a special tool with 63 hardened punch bits 1.35 mm (0.052in) in diameter mounted on a solid base block was constructed to repeat-punch a matrix of holes, on 0.2 in (5.0 mm) spacing, through the copper strips and the base board.
Many dimensional, material quality and tooling problems were encountered before finished boards of acceptable quality could be produced in quantity. These machining problems were encountered due to the non-availability, in 1960, of advanced printed circuit board milling and drilling techniques or facilities for chemical milling (etching) the copper strips.
However, with experience production rates improved and in 1961 Vero Electronics Ltd was formed as a separate company to market the increasing sales of Veroboard.
