General how to calculation of the copper through the current PCB design, how much is the thickness,

CodePudding user response:

According to the 2, 5 a, mm is open

CodePudding user response:

By the size of the current problems related to voltage
General PCB, if not more than 12 v voltage, basically according to 1 mm wide by 1 a to estimate can thickness (1 oz)

CodePudding user response:

Through the current is determined by P=UI, can according to need to drive the power and the applied voltage calculation

CodePudding user response:

Can be roughly 40 mil=1 a according to the inner layer (1 oz (CU), outer 20 mil=1 a (1.5 oz CU), detail can look for the IPC's formula,

CodePudding user response:

When I paint, generally in accordance with the 40 mil line width, flow capacity is calculated on the basis of 1 A, copper thick 1 oz, in practice, of course, generally want to have enough margin,
