PCB design layout grid setting skills
PCB design requires different grid settings at different stages. In the layout phase, large grid points can be used for device layout.For large devices such as ICs and non-positioning connectors, 50 to 100 mil grid precision can be used for layout. For passive small devices such as resistors, capaci
