: Hi Paul,
: The answer to you first question is yes.
: We can reliably produce track widths of 0.15mm.
: Our minimum gap requirments are also 0.15mm.
: Please take a look at the following link from our website for more information.

Thank you for your reply.

I get that: Multilayer clearance recess on inner layers(M) = 0.5mm.

Does this imply that on the inner layers, the minimum separation between the vias (from their drill edges NOT their centers)is equal to "minimum annular ring around via (C-D = 0.3mm)" plus two times "Multilayer clearance recess on inner layers(M = 0.5mm)"? That is:
minimum separation between vias on inner layers= 0.3mm + 1mm = 1.3mm?

I cannot find the minimum separation between vias (from their drill edges NOT their centers) on the outer layers though. could you please instruct me on how to get this information?

The minimum non-copper region between the pads has to be equal to the minimum air gap (ie: 0.15mm)?

Regards,
Paul.
