The impedance of flexible printed circuit boards (FPC) is a critical parameter that affects circuit performance, consisting of resistance and reactance. It plays a crucial role in determining how current flows through the circuit and is essential for ensuring good conductivity and signal transmission performance during electronic component installation. Materials with low resistivity are crucial for maintaining desired impedance levels and meeting quality standards in the production process.

FPCB is a flexible circuit board that offers advantages such as lightness, thinness, and flexibility compared to rigid PCBs, but specific design considerations need to be taken into account, including connection methods, ESD shielding, flexibility requirements, protection measures, stiffener design, air gap layers, double-sided tape fixing, and positioning silk screen line.
Flexible Printed Circuit Board (FPC) with RF connectors, featuring varying pitches, are crucial components in electronic devices, integrating LCD controllers and reducing pin count, with applications across diverse industries, offering features like malleable pin designs and impact-resistant back-lock systems for versatile usage in mobile phones, automotive electronics, and more.
FPCs offer significant advantages over rigid PCBs but face production challenges, necessitating rigorous testing. Existing defect detection methods are insufficient, requiring higher accuracy due to unique FPC characteristics, such as deformation-prone templates and reflective surfaces, making manual inspection costly and inefficient.

FPC connectors, or flexible printed circuit board connectors, are known for their flexibility and foldability, making them ideal for connecting in tight spaces with strong resistance to vibration and fracture. They are made of conductive metal film materials and consist of wires, protective layers, and connector seats. FPC connectors offer several advantages, including flexibility, electromagnetic shielding performance, high transmission rates, and low insertion and removal forces, making them widely used in high-speed transmission and frequent connection scenarios, especially in mobile communication devices. Their structure includes a rubber core, tongue, terminals, and welding pads, each serving specific functions. FPC connectors can be classified into different types based on structural characteristics, connection methods, PCB matching methods, insertion force, and the direction of the frame opening. They have good electrical performance, reducing signal interference and distortion during transmission, and can connect signal transmission between different electronic device boards.
