In the 5G era, the key materials of PCB boards for base stations play a vital role in performance and quality. This article will provide an in-depth analysis of this knowledge and provide reference information for engineers and technicians. First of all, the base material is the basis of the PCB board. Common substrates include FR4, ceramic substrates, etc., which need to have good thermal conductivity and electrical properties to meet the transmission requirements of high-frequency signals. Choosing the right base material can significantly improve the stability of 5G base stations. Next is **Copper Foil**, which serves as a conductive layer and plays a key role in the PCB board. High-quality copper foil must not only have high conductivity, but also have good corrosion resistance. Studies have shown that a layer of high-quality copper foil can improve the conductivity of PCB boards by 30%. The role of **insulation layer** cannot be ignored. Not only does it need to isolate current, it also needs to have high temperature stability and excellent mechanical properties to prevent short circuits and other failures. Appropriate selection of insulation materials can significantly reduce the failure rate of base stations. Finally, **high frequency performance** is one of the core indicators of PCB boards for 5G base stations. High-quality PCB materials can reduce signal attenuation and ensure the stability of signal transmission. By understanding these critical materials and their performance requirements, engineers can make more informed decisions during the design and procurement process.
