What is the meaning of PCBA?
Printed circuit boards, also known as printed circuit boards, printed circuit boards, often use the English abbreviation PCB (Printed circuit board), which is an important electronic component, a support for electronic components, and a provider of circuit connections for electronic components. Because it is made using electronic printing technology, it is called a "printed" circuit board.
Before the advent of printed circuit boards, the interconnection between electronic components relied on the direct connection of wires to form a complete circuit. Now, the circuit panel only exists as an effective experimental tool, and the printed circuit board has become an absolute dominant position in the electronics industry. At the beginning of the 20th century, in order to simplify the production of electronic equipment, reduce the wiring between electronic parts, and reduce production costs, people began to delve into the method of replacing wiring with printing. Over the past 30 years, engineers have repeatedly proposed to use metal conductors for wiring on insulated substrates. The most successful was in 1925, Charles Ducas of the United States printed circuit patterns on an insulating substrate, and then used electroplating to successfully establish conductors for wiring.
Until 1936, Austrian Paul Eisler (Paul Eisler) published the foil film technology in the United Kingdom, he used a printed circuit board in a radio device; and in Japan, Miyamoto Yoshinosuke used the spray-attached wiring method "メタリコンMethod of Wiring Wiring (Patent No. 119384)" successfully applied for a patent. Among the two, Paul Eisler’s method is the most similar to today’s printed circuit boards. This type of method is called subtraction, which removes unnecessary metal; while Charles Ducas and Miyamoto Kinosuke’s method is to add only what is needed Wiring is called the additive method.
Even so, because the electronic components at that time generated a large amount of heat, the substrates of the two were difficult to use together, so that there was no formal practical use, but it also made the printed circuit technology further.
