How does PCB trace impedance relate to current flow in PCB trace calculations?

Hello

Can anyone please help me in understanding the PCB trace impedance calculation w.r.t. the current flowing in the trace??

Hi, Gaurav gupta

It is the material specification of the di- electric constant of the copper material used in pcb track designing and is measured in tg for 1mm length of the material capable of withstanding the current flow ,if the tg is more the conduction will be very good , but for higher tg material cost will be very high. when designing pcb tracks gnd and +ive tracks should be bigger and sufficient gap should be given for the signal tracks to avoid inter signal track leakages.

Hi Sambath,

Thanks for your response. It helped me in understanding the trace impedance concept.
