Reasonable layout of PCB components is the basic premise to design high-quality PCB drawings.
PCB layout design is the first important process in the whole PCB design process. The more complex the PCB is, the layout will directly affect the difficulty of later wiring. Layout design is to place devices in PCB frame according to the design requirements. Generate network table in schematic tool (design → create netlist), then import network table in PCB software (design → import netlist).
