== Production == Production of the proposed new product, Veroboard, was undertaken by the VPE machine tool department.{{citation needed|date=April 2017}} Bought-in sheets of 1.6 mm (0.06 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.<ref>{{cite web |title=Side-and-face Mill Cutter|url=https://www.google.co.uk/search?q=side+and+face+mill+cutter&tbm=isch&tbo=u&source=univ&sa=X&ei=Ycf0UrOILY_H7Ab-5oGQAw&ved=0CDwQsAQ&biw=1228&bih=709}}Google Images</ref> For a second operation a special tool with 63 hardened punch bits 1.35 mm (0.052 in) in diameter mounted on a solid base block was constructed to repeat-punch a matrix of holes, on {{convert|0.2|in|abbr=on}} spacing, through the copper strips and the base board.{{citation needed|date=April 2017}} 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.{{citation needed|date=April 2017}} In 1961, as production rates improved with experience, Vero Electronics Ltd was formed as a separate company to market the increasing sales of Veroboard.{{citation needed|date=April 2017}}
