(How to design a PCB circuit board We all know that the principle of making a PCB board is to turn the designed schematic into a real PCB circuit board. Please don’t underestimate this process. There are many tools that work in principle. It is difficult to realize in engineering, or the tools that others can realize cannot be realized by others. Therefore, it is not difficult to make a PCB board, but it is not a simple work to do a PCB board well.)
