4. What’s the typical process flow for multi-layer PCB?
Material cutting → Inner dry film → inner etching → Inner AOI →
Multi-bond→ Layer stack up Pressing → Drilling → PTH → Panel
Plating → Outer Dry Film → Pattern Plating → Outer etching → Outer
AOI → Solder Mask → Component Mark → Surface finish → Routing → E/T
→ Visual Inspection.
