Who is the father of PCB industry?

The inventor of the printed circuit board is an Austrian named PaulEisler, who adopted the printed circuit board in a radio device in 1936. In 1943, Americans have widely used this technology in military radios. 1948, the United States officially recognized the invention for commercial use. 2 1, 65438, in June, 1950, Paul isler obtained the invention patent of the circuit board, which has been just 60 years.

This man, known as the "father of circuit boards", has rich life experiences, but he is rarely known by colleagues of PCB manufacturers.

In fact, isler's life story, as described in his autobiography My Life and Printed Circuit, is like a mysterious novel, full of persecuted subjects.

Isler 1907 was born in Austria, and 1930 graduated from the University of Vienna with a bachelor's degree in engineering. At that time, he showed the talent of an inventor. However, his primary goal is to find a job on non-Nazi land. However, due to the special environment, the Jewish engineer fled Austria in 1960s and 1930s. Therefore, in the 1960s +0934, he got a job in Belgrade, Serbia, designing an electronic system for trains-allowing passengers to record personal records through headphones, just like an iPod. However, at the end of the work, the customer provided food, not money. Therefore, he had to return to his hometown Austria.

After returning to Austria, isler contributed to newspapers, founded radio magazines and began to learn printing technology. Printing was a very powerful technology in the 1930 s, and he began to imagine how to apply printing technology to circuits on insulating substrates and put them into mass production.

1936 he decided to leave Austria. He was invited to work in Britain, based on two patents he has put forward: one is graphic impression recording, and the other is stereoscopic TV with vertical resolution line.

He sold his TV patent for 250 francs, which is enough for him to live in an apartment in hampstead for a while, which is a good thing because he can't find a job in London. A telephone company likes his idea of printed circuit board very much-it can eliminate the bundled wires used in the telephone system.

Due to the outbreak of World War II, isler began to try to get his family to leave Austria. At the beginning of the war, his sister committed suicide and he was detained as an illegal immigrant in Britain. Even though he was locked up, isler was still thinking about how to help the war.

After his release, isler worked for Henderson, a music printing company. Spalding's works At first, his goal was to improve the company's drawing music typewriter, not in the laboratory, but in a bombed-out building. H.V.Strong, the boss of the company, forced Eisler to sign all the patents that appeared in the research. This is not the first time or the last time to use isler.

One of the troubles of a soldier's job is his identity: he has just been released. But he still went to the military contractor to discuss how his printed circuit could be used in the war.

Through his work in Henderson. In Spalding's work, isler developed the concept of using etched foil to record traces on the substrate. His first circuit board looks more like a plate of spaghetti. He applied for a patent at 1943.

At first, no one really paid attention to this invention until it was applied to the shooting down of V- 1 Buzzer by a cannonball fuze. After that, isler got a job and gained some fame. After the war, this technology was spread. The United States stipulates in 1948 that all airborne instruments must be printed.

Isler's 1943 patent was finally divided into three independent patents: 63911(three-dimensional printed circuit board), 639 178 (foil technology of printed circuit) and 639 179 (foil technology of printed circuit). These three patents were published on June 2 1950, but only a few companies were granted patents.

In the1950s, isler was used again, this time working for the British National Research and Development Corporation. The organization basically leaked isler's American patents. But he continued to experiment and invent. He also came up with ideas such as battery foil, heated wallpaper, pizza oven, concrete mold and defrosting of rear window. He succeeded in the medical field and died in 1992. He owned dozens of patents in his life. He has just won the Nufield Silver Medal from the Institute of Electrical Engineers.
