I’m making the move from 2 layer boards to 4 layer. With the specifications from the support knowledge base it gives the minimum trace width (6mil for 2 layer) and minimum inner trace width (8mil 4 layer boards).
So I’ve made up a board with 6mil traces on the top and bottom layer and 8mil mm traces in the middle two.
When i run the seeedstudio 4 layer DRC i get width errors on the top and bottom layers, as the DRC is set to 8 mil.
Is this because of a limitation with eagle where it cannot define different rules for each layer or does it mean that if i want a 4 layer board I need to make all the widths 8mil?
