Flex or Flexible PCB is a type of printed circuit board (PCB) designed to provide flexibility and durability for applications in harsh environments. It is made from a thin layer of copper foil laminated to a flexible substrate material, such as Kapton, polyimide, or polyester. Flex PCBs are resistant to extreme temperatures, moisture, and other environmental factors, making them an ideal choice for applications in industrial, aerospace, and military sectors. Flex PCBs offer superior reliability and performance compared to traditional rigid PCBs, making them the preferred choice for PCB prototype and PCB board assembly.
