What kind of plate to choose and production and processing method for PCB high frequency board

High-frequency boards refer to special circuit boards with high electromagnetic frequencies, which are used for PCBs in the fields of high frequency (frequency greater than 300MHZ or wavelength less than 1 meter) and microwave (frequency greater than 3GHZ or wavelength less than 0.1 meters). The copper plate is a circuit board produced by using part of the process of the ordinary rigid circuit board manufacturing method or using a special treatment method. Generally speaking, a high-frequency board can be defined as a circuit board with a frequency above 1GHz.

The role and principle of PCB copper cladding

Copper cladding plays a very important role in the PCB production process. Sometimes the success or failure of copper cladding is related to the quality of the entire board. The so-called copper cladding is to fill solid copper into the idle space of the PCB substrate.

Talking about the impedance control of PCB

With the increasingly complex and high-speed circuit design, how to ensure the integrity of various signals (especially high-speed signals), that is, to ensure the signal quality, has become a difficult problem. At this time, it is necessary to analyze with the help of transmission line theory, and control the characteristic impedance matching of the signal line becomes the key. If the impedance control is not strict, it will cause considerable signal reflection and signal distortion, resulting in design failure. Common signals, such as PCI bus, PCI-E bus, USB, Ethernet, DDR memory, LVDS signals, etc., all require impedance control. Impedance control ultimately needs to be achieved through PCB design
