Full Flex & Flex Rigidised for Folding

Full flex PCBs for folding are built with flexible acrylic or epoxy adhesive in comparison to standard rigid-flex PCBs with prepregs. This offers thinner constructions and smaller bending zones. The rigid area can have multiple layers of flex material or a single layer of glass-reinforced material to rigidise the assembly area.

The flexible materials are very thin and therefore higher packaging densities are possible. The bend zones can be manufactured with mechanical or laser routing. With these technologies very small bend zones are achievable.
