Hi Chris,
I would recommend you the Ellwest KG PCB supplier company
http://www.ellwest-pcb.com/
Mr. Udodov contact is:
viatcheslav.udodov@xxxxxxxxxxx
They offer very special PCBs for us since year 2003, always in time,
with fine lines and small vias, up to 30 layers,
and with strict requirements to the soldermask tolerance.
And they always help with stack-up design, special materials, etc. -
they are really professional guys in PCB supply.
I think we purchased more than 1000 different multilayer part numbers,
from 2 to 200 pcs each, since that time.
As I know they are the official distributor of several advanced PCB
factories which are located in Asia and Europe,
so they could recommend you a right one.

We are designing small PCB's to use as test fixtures for fine pitch wafer
level chip-scale parts (WLCSP). Our current PCB fab seems to be having
issues with tolerance control of the pads and solder mask. Looking for
recommendations of PCB fabs that have very tight process control.
Thanks,
Chris
