Single Sided Flex PCBs from FX PCB offer superior flexibility, lightweight construction, and high-density interconnect capability using polyimide substrates. Designed for medical, automotive, aerospace, and consumer electronics applications, these boards support up to 500 million flex cycles, fine line widths of 2.5mil, and multiple surface finish options for reliable, miniaturized assemblies.




FX PCB's single sided flex PCBs use polyimide (PI) copper-clad laminate as the primary base material. Polyimide is chosen for its exceptional thermal resilience, dimensional stability, and flexibility. Alternative insulating substrates including PET, Aramid Cellulose Ester, and PVC are also available depending on application requirements and environmental conditions.
