I am trying to place a via with a “V” during differential wiring, but when I click on it, it does not place.
Upon closer inspection, it appears that the clearance between the two vias is so large that it is interfering with the other via.
How can I reduce this clearance?
Wiring width is 0.1 mm and wiring spacing is also 0.1 mm.
The clearance between vias is probably about 0.125 mm.
Where can this be set?
The wiring is set in “net class” with USB_90R.
Just for learning:
Place a via somewhere. Hit E to edit it. You will see it has a hole diameter and a pad diameter. That’s what you can change. But follow the limits of the board manufacturer. They are special for vias.
Next step, click on via dropdown (in the upper left of the layout window. And select “Edit predefined Sizes”. That’s where you can predefine different vias to your desire.
It is obvious, that vias take more space than traces. It is a hole + the annular ring.
