Aircraft, anti-theft alarm, computer, dishwasher, escalator. . .
Wait, through the alphabet.
Products made anywhere in the industrialized world have at least one common component: printed circuits.
In printed circuit boards, traditional wires are replaced by conductive material strips laid by the printing process, which eliminates the laborious manual work of connecting wires and avoids faults.
It\'s cheap in quality.
It provides the possibility for interconnect production and promotes the micromation of products such as pocket calculators and cameras.
Paul Eisler, an outstanding pioneer of the technology, invented the FOIL method for producing printed circuits.
In 1936, he came to England from Austria and became a refugee of Nazi persecution.
At first, his invention was not supported by business. He was on the side.
Following up on the research and development work of the Odeon theater cinema, but with the outbreak of World War II, he restored the printing circuit and patents related to his foil making method, it is expected that the demand for electronic products in wartime will provide appropriate opportunities.
A city agency considered supporting him financially, but later refused; in favour of -
He learned later(Sir)
Jet engine project by Frank Whittle
The original creator of Beethoven\'s music, Henderson and spuddin, was bombed.
They saw in the printed circuit the opportunity to start printing again and had Essler lead their instrument department after convincing him to assign all future patents for his invention, symbolically paying £ 1
In this capacity, he showed hundreds of engineers and military personnel, the United Kingdom, the United States and the allies the first radio containing printed circuits.
The most enthusiastic response;
Nevertheless, the Ministry of Supply rejected the invention for military equipment and no industrial company or government department tried it.
The US military then developed a proximity fuse with a printed circuit.
These fuses are installed in air defense shells deployed in Fort Antwerp\'s bridgehead, as well as other shells that help protect London from the V1 rocket.
Eisler subsequently became the technical director of Henderson graph printing Circuit Co. , Ltd. , and established the first factory to manufacture printing circuits in Henderson and spuddin group. Pye (Cambridge)
Subsequently, the Telegraph Condenser Company became the first licensed party.
In the United States, dealgraph Inc. was established, attracting 16 licensees.
After a disagreement with the National Research and Development Corporation, Essler left shopgraph and subsequently worked on other inventions and developments, including foil batteries and electric surface heating.
Until his death, he was interested in the work.
Due to his work in printing circuits, he received honors and awards in France, Italy and the United Kingdom, and the last was the 1992 silver medal from the Association of Electrical Engineers.
The story of Essler\'s life and work is described in his two books, \"My life with printed circuits (1989).
In such an important area, it is not surprising to have opposing claims of various achievements, but on 1969, Esler heard Lord Haman say in the court of appeal: \"There have been many attempts to do similar things before, before Dr. Essler put forward his ideas, none of them turned out to be useful and did not board the workshop at one time.
In addition to being disappointed that his work has not been better understood and publicly recognized, Paul Essler\'s career has been satisfactory, which has exposed him to many well-known people and organizations.
He\'s a quiet and gentle man.
A lonely man has tried several failures and tried to work with others who may have helped him to get a greater material return, which he has developed a technology to do for the rich world(
