Suppose I use a wide trace as a power rail in my circuit (wide enough for the rated current, at a certain copper weight), and it doesn’t have an adjacent ground plane. If I have enough space on the...

From what I understand, PCB manufacturing has a limitation on the minimum width of the solder resist—it cannot be too thin, typically not less than 5 mil. In many components, including those with a...
