Layer 14, third section: combination of soft and hard materials


This 14-layer, three‑material rigid‑flex PCB features an integrated lamination of a rigid PCB and a flexible FPC. Components are mounted on the rigid section, while the flexible section allows for bending and three‑dimensional routing, eliminating the need for numerous connectors and ribbon cables and enhancing reliability. However, the manufacturing process is complex; applications such as foldable displays, endoscopes, and robotic arm joints require copper‑clad laminates and demand careful attention to bend life.
