Re: 4 layer DRU rules - min width 8 mil ?

6 mil would be the minimum and you are less likely to have problems if you use 8 mil. This is quite common with low-cost PCB suppliers - they prefer slightly larger clearances than the minimum.

Re: Fusion PCB Specification

ITead Studio, who uses the same manufacturer as Seeed Studio, specifies copper to edge clearance as > 0.3 mm.
