Short Version: Does anyone know of any inexpensive prototype board houses that can do 20 mil via (10 or 12mil hole) and 5 mil lines and spaces in 4 or 6 layers?
Long Version:
There are a lot of prototype PCB suppliers that produce 4 and 6 layer PCB's at realativly low cost.
less than $400 a lot, some a lot less.
None of these that I am aware of can do 20mil vias (10 ro 12 mil holes) and 6 mil lines/spaces (prefer 5 mil lines and spaces)
I'm currenlty paying big bucks ($1K+ /lot) for my prototype boards becuase using BGA parts requires the small vias and tight trace specifications.
