PCB (Printed Circuit Board) is an industry with a relatively low technical threshold. However, 5G communication has the characteristics of high frequency and high speed. Therefore, 5G PCB requires higher technology and the industry threshold is raised; at the same time, the output value is also pulled up.
Via hole is also called via hole. In order to meet customer requirements, the via holes must be plugged in the PCB process. Through practice, it has been found that in the process of plugging, if the traditional aluminum sheet plugging process is changed, and the white mesh is used to complete the board surface solder mask and plugging, the PCB production can be stable and the quality is reliable.
Multi-layer PCBs are used as the "core main force" in the fields of communications, medical treatment, industrial control, security, automobiles, electric power, aviation, military industry, and computer peripherals. Product functions are getting higher and higher, and PCBs are getting more and more sophisticated, so relative to the difficulty of production Also getting bigger.
We all know that there are many procedures for making HDI PCB from the planned feeding to the final step. One of the processes is called browning. Some people may ask what is the role of browning?
The advantages of heavy copper PCB make it the top priority for the development of high-power circuits. The heavy copper concentration can handle high power and high heat, which is why high-power circuits have been developed using this technology. Such circuits cannot be developed with low-copper concentration PCBs because they cannot withstand the huge thermal stresses caused by high currents and flowing currents.
