Why Is The Usage Frequency Of Printed Circuit Board So High?

Printed circuit board is a board that combines conductive copper layers with insulating substrates through etching and other processes to form wire paths, and connects electronic components through soldering. It is the "nerve center" of modern electronic devices and carries the core function of signal transmission to electrical connections.

Meanwhile, printed circuit boards are ubiquitous, from smartphones, laptops, home appliances, automotive electronics in your hands, to industrial control and medical imaging equipment, to defense radars and 5G communication base stations, almost all electronic products and tablet devices rely on Printed circuit boards.

Because of the high frequency of use, printed circuit boards require precise production, especially high-frequency Printed circuit boards. The material and layout design must strictly control impedance and dielectric constant to reduce signal distortion and loss; It is best to use FR-4 substrate as the material, which has good mechanical strength and insulation performance, while high-frequency materials, metal substrates, etc. meet specific temperature and heat dissipation requirements; Through precise stacking, multi-layer wiring, and compatible flexible design of Printed circuit boards, it is possible to adapt to the demands of new products with smaller dimensions and higher performance.
