PCB News - 5G circuit board

Copper clad laminate industry is in the middle of the whole PCB industry chain, providing raw materials for PCB products.

Copper clad laminate is a kind of plate-like material made by dipping electronic glass fiber cloth or other reinforcing materials into resin adhesive, drying, cutting and stacking into blank, covering one or both sides with copper foil and hot-pressing. It is mainly used for the production of printed circuit board (PCB), and plays the role of interconnecting conduction, insulation and support for PCB.
The upstream of the industrial chain is raw materials such as electrolytic copper foil, wood pulp paper, glass fiber cloth and resin; the downstream is PCB products; the terminal industry is aerospace, automobile, home appliance, communication and computer, etc.

19 years in 5 g preliminary commercial, upstream of the core materials such as high frequency copper clad products raw materials with the traditional similar CCL, after downstream PCB manufacturer is suitable for high frequency of high frequency circuit board after applied to the base station antenna module, power amplifier module, such as equipment components, and ultimately is widely applied in communication base station (antenna, power amplifier, low noise amplifier, filter, etc.), automotive auxiliary system, space technology, satellite communications, satellite TV, military radar, and other areas of the high frequency communication.

5G high frequencytechnology puts forward higher requirements for circuits.
The rf circuit with operating frequency above 1GHz is generally referred to as high-frequency circuit. In the process of mobile communication from 2G to 3G and 4G, the communication frequency band develops from 800MHz to 2.5ghz. In 5G era, the communication frequency band will be further improved.
PCB board will be equipped with antenna vibrators, filters and other devices in 5G rf.

According to the requirements of the Ministry of Industry and Information Technology, it is expected that the early 5G deployment will adopt the 3.5ghz band, with the 4G band mainly around 2GHz.
Generally, the electromagnetic wave with a wavelength of 1~10 mm in the 30~300GHz band is called millimeter wave.
