What is Flexible PCB?
A Flexible PCB, or flex printed circuit board, is a type of PCB designed to bend and flex to fit into compact spaces. Made from flexible materials like polyimide, Flex PCBs are used in applications where space is limited and flexibility is essential, such as in wearable devices, smartphones and medical equipment. They offer advantages in terms of reliability, weight reduction, and design versatility. JLCPCB utilizes cutting-edge production technology to deliver premium Flexible PCBs that meet the demands of complex, lightweight and compact applications. Our Flex PCBs offer superior performance, improved thermal management, and seamless integration possibilities. 
Standard 2-Layer Flexible PCB Stackup
Standard 0.11mm 2-layer Flex PCB features a carefully structured stackup for optimal performance in compact and flexible applications. The stackup includes two 12μm copper layers separated by a polyimide dielectric with a dielectric constant (Dk) of 3.3 and 2.9, offering excellent electrical insulation and flexibility. Each copper layer is bonded with 15μm adhesive, ensuring strong layer integrity. The total thickness of 104μm provides a balance between flexibility and durability, making it suitable for intricate designs and dynamic environments. 
Common Applications of Flexible PCBs
