The main conductor material used in PCBs is copper foil, which is used for transmitting signals and currents. At the same time, the copper foil on the PCB can also serve as a reference plane to control the impedance of transmission lines or as a shielding layer to suppress electromagnetic interference (EMI). Additionally, during the … Read more
In hardware design, PCB design is a very important and indispensable step. For some simple products, PCB design may simply involve connecting all components and networks accordingly. However, for high-speed circuits and RF circuits, the design of the PCB directly affects whether the product functions properly and whether it meets market requirements. Below, I will … Read more
(There are benefits at the end of the article, don’t miss out!) As electronic devices develop towards higher performance and smaller sizes, the precision and performance requirements for PCBs are also increasing. High multilayer PCBs can provide more routing layers, allowing for more complex and dense circuit designs, thus meeting the demands for high-frequency and … Read more
