Which layer counts and materials are available?

We build boards from 1 to 20 layers. Priced instantly online: FR-4 (Tg130, Tg150, Tg170), aluminum core, copper core and flex (polyimide). Quoted by an engineer: Rogers and PTFE (Teflon) high-frequency boards. Standard board thickness is 0.4–3.0 mm and outer copper is 1–2 oz. The PCB capabilities page has the full table. If your design falls outside it, contact us and an engineer will check whether it can be built.
