What The Plant Can Actually Hold And What It Runs On
Three capability tables, twenty-seven process stations and the certifications the company records. Published in full rather than summarised, so you can check your design before you order.
Rigid PCB Capacity
The published process limits for FR4 boards from 1 to 16 layers. These are limits rather than recommendations, and a design that sits at the limit everywhere will yield worse than one that approaches it only where it must.

Aluminium PCB Technical Standard
Metal core boards behave differently from FR4 in every dimension that matters. Minimum features are coarser, tolerances are looser, and the thermal and dielectric properties are the reason to use them.
