This study reviews the development of printed circuit technology from its origins before the Second World War until the present day. Various inventions appeared before the war for producing circuits on a flat surface, but it was not until Dr Paul Eisler had the idea of utilising the long established arts of the printing industry that viable methods of production were established. Stimulated by the release of an American official secret of the use of a printed circuit in a proximity fuse, and the first Technical Symposium in 1947, government and industries researched into the best ways of producing planar circuits. Dr Eisler's etched foil method emerged as the most practical technique. The first decade of the technology was spent learning and refining print and etch techniques, during which time printed circuits gradually became accepted by the consumer industry, as well as by industry and government bodies. Most of the major advances were made during the second decade, such as plated‐through hole, multilayer and additive processes. Since then manufacturing technique has been consolidated and refined, affected by the continuing demands of the electronics industry for increasing miniaturisation and packaging densities.

Briefly reviews previous literature by the author before presenting an original 12 step system integration protocol designed to ensure the success of companies or countries in their efforts to develop and market new products. Looks at the issues from different strategic levels such as corporate, international, military and economic. Presents 31 case studies, including the success of Japan in microchips to the failure of Xerox to sell its invention of the Alto personal computer 3 years before Apple: from the success in DNA and Superconductor research to the success of Sunbeam in inventing and marketing food processors: and from the daring invention and production of atomic energy for survival to the successes of sewing machine inventor Howe in co‐operating on patents to compete in markets. Includes 306 questions and answers in order to qualify concepts introduced.
