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

Some small principles of PCB board technology
Printed wire width selection basis:The minimum width of the printed wire is related to the amount of current flowing through the wire:The line width is too small, the resistance of the printed wire is large, and the voltage drop on the line is large, which affects the performance of the circuit.If t
