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
