The HDI high-frequency PCB board is mainly a special kind of PCB circuit board with high electromagnetic frequency. Because its physical indicators, precision and technical parameters and other indicators have high requirements, it is necessary to pay careful attention to each one during production.

1. The impedance control concept is introduced to distinguish the resistance of direct current (DC). The resistance encountered by alternating current is called impedance (Z0), including resistance (R), inductive reactance (XC) and capacitive reactance (XL). Special impedance is also called "special impedance". Refers to the transmission signal line at a certain frequency (that is, the copper wire of the circuit board we manufacture)

In recent years, the PCB circuit board industry has become a world-wide industry. There are more than 2,800 printed circuit board companies in the world, with an output value of more than 50 billion US dollars, accounting for more than 1/4 of the total output value of the electronic component industry.

Mobile communication information is transmitted using electromagnetic waves as the medium. The main function and function of the base station is to receive and transmit wireless signals, convert wireless signals into optical/electrical signals that are easy to transmit, realize information transmission between different terminals, and distinguish between different frequencies signal.
