Valiant Electronics is a Rigid-Flex Printed Circuit Board Manufacturer.  Rigid-Flex PCBs are rigid and a flex PCB connected together.   This type of PCB is usually used when you need wires to be connected to a PCB, however, instead of using wires you use a flexible PCB which is far way more efficient than wires and keep your design looking more tidy and organized.
