Veroboard was originated and developed in the early 1960s by the Electronics Department of Vero Precision Engineering Ltd (VPE). It was introduced as a general-purpose material for use in constructing electronic circuits - differing from purpose-designed printed circuit boards (PCBs) in that a variety of electronics circuits may be constructed using a standard wiring board.

The first single-size Veroboard product was the forerunner of the numerous types of prototype wiring board which, with world-wide use over five decades, have become known as Stripboard.

The generic terms 'veroboard' and 'stripboard' are now taken to be synonymous.

History

edit

The VPE Electronics Department was formed early in 1959 when managing director Geoffrey Verdon-Roe hired two former Saunders-Roe Ltd employees, Peter H Winter (aircraft design department) and Terry Fitzpatrick (electronics division).

 
Veroboard Patent

After the failure of a project to develop machine tool control equipment the department remained operative as a result of success with the invention and development of the new electronics material - Veroboard.

The printed circuit board (PCB) had become commonplace in electronics production by the mid-1950s and new equipment utilising PCBs was displayed at the 1959 Radio and Electronics Components Manufacturers Federation (RECMF) Exhibition held in the The Dorchester Hotel, Park Lane, London. [1]

The usual configuration for most of the PCBs of that time had components placed in a regular pattern with the circuit formed by maze-like conductive pathways. An interesting alternative, proposed by Fitzpatrick after visiting the RECMF Exhibition on behalf of VPE, envisaged a standard circuit board carrying straight-line conductors on which the components could be suitably dispersed and connected to the conductors to produce the required circuit.

A patent application was immediately filed and the invention was developed for Vero by associates Winter, Fitzpatrick and machine shop engineers.


Production

edit

Production of the proposed new product, Veroboard, was undertaken by the VPE machine tool department.

Bought-in sheets of 1.6mm (0.2in) copper-clad SRBP printed circuit material were cut to give 122mm x 456mm (4.8in x 18in) size boards with the individual boards then being machined to form the final product according to the original Veroboard specification. [2]

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. [3]

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.

Utilization

edit

As with other stripboards, in using Veroboard, components are suitably positioned and soldered to the conductors to form the required circuit. Breaks can be made in the tracks, usually around holes, to divide the strips into multiple electrical nodes enabling increased circuit complexity.

This type of wiring board may be utilised for initial electronic circuit development, to construct prototypes for bench testing or in the production of complete electronic units in small quantity. Veroboard was first used for prototype construction within Vero Electronics Department in 1961. The images of a binary decade counter sub-unit clearly show both the assembled components and the copper conductors with the required discontinuities.

A number of these sub-units were interconnected through connectors mounted on a motherboard similar to that shown in the Veroboard Display image and perhaps comprised a very early PCB-based backplane system. It may be of interest to note that each sub-unit had a digital capacity equivalent to 1/2 byte of data storage - ie 2,000,000 would be required to store 1Megabyte.

The versatility of the veroboard/stripboard type of product is demonstrated by the large number of design examples currently (2013-07) to be found on the Internet. [5]

Update

edit

The advent of the Arduino integrated development environment, designed to introduce computer programming to newcomers unfamiliar with software development, presents a new opportunity to utilise Veroboard. [6]

The British company Vero Technologies Ltd currently holds the UK trademark for Veroboard. [7]

In America the Veroboard trademark is now held by the Canadian company Pixel Print Ltd. of Vancouver. [8]
