FR4 stacks up to 64 layers
Regular Rigid PCB
Standard FR4 construction is where most programmes start, and where aspect ratio, Tg selection and expedited sample time decide whether a schedule holds.
Published capability limits
- Up to 64 layers
- FR4 TG135 / TG150 / TG170
- Halogen free / CTI ≥ 600
- Aspect ratio (finished hole) 28:1
- Sample expedited 8 hours (1–2 layer)

Gerber plus a stack-up note is enough to start. If the design sits outside the window above, we will say so and propose the change that brings it back in.
