Flex Circuit Prototype



FPC Design




Flex circuit prototype refer to the initial versions or samples of PCBs . These prototypes developed to validate the design, functionality. and manufacturing feasibility of a flex circuit before full-scale production. It involves developing a small-scale version of the final flex PCB design. to validate its functionality, performance, and manufacturability before proceeding to mass production. Flex PCB prototyping allows engineers and designers to evaluate and refine their designs. identify any potential issues, and make necessary modifications more cost-effectively.
