pcb The History of Printed Circuit Boards Before the emergence of printed circuit boards, the interconnection between electronic components depended on the direct connection of wires, forming a complete route. In contemporary times, circuit boards are just an effective experimental tool, and printed circuit boards have become the dominant force in the electronics industry.
At the beginning of the 20th century, in order to simplify the production of electronic machinery, reduce the wiring between electronic components, and lower production costs, people began to study the method of using printing instead of wiring. For the past 30 years, engineers have been proposing the use of metal conductors as wiring on insulating substrates. The most successful one was the 1925 American Charles Ducas route pattern printed on an insulating substrate, and then successfully established conductors as wiring through electroplating.
Until 1936, Austrian Paul Eisler's foil technology was published in England, where he used printed circuit boards in radio equipment; In Japan, Yoshinobu Miyamoto successfully applied for a patent for the spray coating wiring method "Megacon (Patent No. 119384119384)". Paul Eisler's method is most similar to today's printed circuit boards. This method is called subtraction, which removes unnecessary metals; CharlesDucas， Miyamoto's favorite method is to only add the required wiring, which is called the reward method. However, due to the high heat generated by electronic components at that time, it was difficult to use both substrates together, so there was no formal practical operation, but it also advanced the technology of printed circuits.

pcb The Development of Printed Circuit Boards: In the past decade, China's Printed Circuit Board (PCB) manufacturing industry has developed rapidly, with total output and output ranking first in the world. Due to the rapid changes in electronic devices, price wars have altered the structure of the supply chain. Considering the distribution of industries, costs, and market advantages, China has become the world's most important production base for printed circuit boards.
Printed circuit boards have evolved from single-layer to double-sided, multi-layer, and flexible boards, constantly moving towards high precision, high density, and high reliability. In the future development of electronic products, continuously reducing volume, lowering costs, improving performance, and promoting printed circuit boards will still maintain strong vitality.
The future development trend of printed circuit board manufacturing technology is towards high-density, high-precision, fine aperture, thin wire, small spacing, high reliability, multi-level, high-speed transmission, and lightweight direction.
