What is a PCB circuit board? PCB printed circuit board is one of the important components of the electronic industry. It is also the support of electronic components and the medium for electrical connection of electronic components. It is called electronic printing because it is made from electronic printing and is also a "printed" circuit board.
What is that FPC circuit board? FPC is a type of PCB, also known as "flexible circuit board" or "soft board". FPC is a kind of printed circuit board with high reliability and good flexibility, which is made of polyimide or polyester film. It has the characteristics of high wiring density, light weight, thin thickness, and strong bending.
Differences between PCB circuit boards and FPC circuit boards
PCB generally uses FR4 as the substrate, also known as hard board, and cannot be bent or bent; FPC generally uses PI as the substrate, which is a flexible material that can be bent or bent
FPC can withstand millions of dynamic bends without damaging the wires. It can be freely moved and expanded according to the spatial layout requirements, achieving three-dimensional assembly and achieving component assembly and wiring integration effects that cannot be compared to other types of circuit boards.
FPC is not only a flexible circuit board, but also an important component connecting three-dimensional circuit structures. This structure can be combined with other electronic product designs to create various applications. PCB circuit boards are usually flat, and the commonly used space expansion solutions are application slots and interface cards. However, as long as FPCs are designed with switches, similar structures can be made, with more flexible orientation design and connector connection. In order to adapt to different product shapes, FPC can connect two rigid boards to form a set of parallel circuit systems, and can also rotate at any angle.
