As you can see, the thickness of the power line, blue line and red line on the circular pad is different. Is this feasible? The line to the left of the right square pad and the line above it are also different in thickness. Is this OK? I heard that this situation will reflect under high frequency signals? So what is the frequency of this high-frequency signal that can not be ignored? Is there 200kHz?

 

Your questions make no sense. Which is the power line? What are we even looking at? What is the pink... the purple... the grey? Anyway, you are the designer. Make the thickness of the line what you want them to be.

And 200 kHz is not considered high frequency. You don't have to worry about that.

 

Different line widths are not a problem but I believe the thickness of all the traces need to be the same, since that's determined by the blank PCB board stock they start with.

Thanks for your reply.I have already do that.
