DirtyPCBs support / 4 layer board details
Hello,

A few questions regarding the 4 layer PCB:

1) Are blind or buried vias allowed?

2) What are your preferred gerber layer names for the internal layers?  The individual drill files if blind/buried vias are allowed?  All layers are positive?

3) Data on the 4 layer dielectric?  For example, oshpark uses FR408 from Isola and links a datasheet.  Does your 4 layer house use that exact same material from the manufacturer?  You can tell I am doing this for RF/microwave :) (up to 12GHz actually)

I'm more inclined towards Dirty because 1) no yucky purple color and 2) hopefully blind/buried vias are supported.

Thank you
