Introduction The 21st century is a knowledge economy era dominated by the electronic information industry. A great change is taking place in the information field, and its leading force and decisive factor are microelectronic integrated circuits. The increasing maturity of silicon chip technology, especially deep submicron (DSM) and very deep submicron (VDSM) technology, has greatly…

PCB design copper plating is a very important part of circuit board design. What is PCB copper plating? It is to fill the idle space in the non-wiring area on the PCB with solid copper. The significance of copper plating is to reduce the ground impedance and improve the anti-interference ability; reduce the voltage drop,…

With high-speed signal transmission, high-speed PCB design has higher requirements. Impedance control is a conventional design of high-speed PCB design. There will be processing errors in more than a dozen processes of PCB processing. At present, the impedance control of conventional board factories is within 10% error. In theory, the smaller the value, the better….
