Alignment

Property  
Min. distance layer to layer 0,05 mm
Innerlayer – layer to layer tolerance +/-0,05 mm
Min. isolation hole - innerlayer 0,175 mm

Inner layer align, tolerances, drill to copper and build up
Min distance between layer to layer: A = 0.05mm
Tolerance innerlayer - hole alignment: B +/- 0.1mm
Min isolation from edge of hole  to copper: C = 0.175mm (up to 8 layers, non-blind hole)
