Hello,

I'm using eagle to design a PCB. In the layout, I got a width error. The trace width is 0.1mm and the minimum width is set to 0.005mm. I'm wondering where does this error come from?

I created another dummy layout and I use the same DRC setting as in the previous one and it has no error. Any explanation for that?!

Thanks.

Dima
 

Hi,

This is only a vague description. Impossible to reproduce it.

Maybe show us: .brd, .erc, .drc files
Or a screenshot with the error description and the error position and layer.

I attached the photos. The first one where I have no trace routing and there is no error. The second photo is when I route, it gives me an error although the trace width>0.005mm as shown in the third photo. Now, i tried to increase the trace width to 0.3mm and the number of errors is reduced from 5 to 4 as shown in the 4th photo.

Please, advise.
 

You may be looking for the wrong DRC rules. Do you have additional width rules for net classes in effect?
 

You are right. I didn't know that I need to look at the net classes. The default minimum width was 0.3mm so that is why when I increased the trace width to 0.3mm the error was removed. It makes sense now. Thank you very much for your help. Appreciated!
