PCBA processing factory introduces the historical origin of circuit boards
At present, the country has higher and higher requirements for environmental protection and greater efforts in link governance. This is a challenge but also an opportunity for PCB factories. If the PCB factory is determined to solve the problem of environmental pollution, then FPC flexible circuit board products can be at the forefront of the market, and the PCB factory can get the opportunity to develop again.
PCBA processing plant introduces printed circuit boards, also known as printed circuit boards, printed circuit boards, often used in English abbreviation PCB (Printed circuit board), is an important electronic component, a support for electronic components, and a circuit connection for electronic components. Provider. Because it is made using electronic printing technology, it is called a "printed" circuit board.

PCBA processing plant said that 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 breadboard 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.

PCBA processing factory was introduced until 1936, Austrian Paul Eisler (Paul Eisler) published foil film technology in the United Kingdom [1], he used a printed circuit board in a radio device; and in Japan, Miyamoto Kinosuke Successfully applied for a patent with the spray-attached wiring method "Metalcon method blowing wiring method (Patent No. 119384)". [2] 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 The required wiring is called the additive method. Even so, because the electronic components at that time generated a lot of heat, the substrates of the two were difficult to use together [1], so that there was no formal practical use, but it also made the printed circuit technology further. iPCB has passed ISO9001:2008, ISO14001, UL, CQC and other quality management system certifications, produces standardized and qualified PCB products, masters complex process technology, and uses professional equipment such as AOI and Flying Probe to control production and X-ray inspection machines. Finally, we will use double FQC inspection of appearance to ensure shipment under IPC II standard or IPC III standard.
