1.How to choose PCB material? The selection of PCB material must strike a balance between meeting design requirements and mass production and cost. Design requirements include electrical and mechanical parts. Usually, this material issue is more important when designing very high-speed PCB boards (frequencies greater than GHz). For example, the dielectric loss of the commonly…

Electronic circuit diagrams are used to represent the composition, structure, nominal value of components and other information of actual electronic circuits. The actual circuit situation can be known through the circuit diagram. In this way, when we analyze the circuit, we don’t have to turn the physical object over and over again, but just take…
