flexible circuit board


Flexible Printed Circuit can be freely bent, wound and folded. Flexible circuit board is made of polyimide film as substrate. It is also called soft board or FPC in the industry. Flexible circuit board is based on The process flow is divided into double-sided flexible circuit board process flow and multi-layer flexible circuit board process flow. FPC soft board can withstand millions of dynamic bending without damaging the wire, can be arranged arbitrarily according to the space layout requirements, and can be arbitrarily moved and expanded in three-dimensional space to achieve integration of component assembly and wire connection; flexible circuit board can be It greatly reduces the size and weight of electronic products, and is suitable for the development of electronic products in the direction of high density, miniaturization, and high reliability.


As more and more mobile phones adopt a flip structure, flexible circuit boards are increasingly being adopted. According to the combination of the substrate and the copper foil, the flexible circuit board can be divided into two types: a flexible flexible board and a non-adhesive flexible board.


The price of the non-adhesive flexible board is much higher than that of the flexible board with glue, but its flexibility, the bonding strength of the copper foil and the substrate, and the flatness of the pad are also better than those of the flexible board. Therefore, it is generally only used in those occasions where the requirements are very high, such as: COF (CHIP ON FLEX, mounting bare chip on flexible board, high requirements on pad flatness).


Due to its high price, most of the flexible boards currently on the market are still flexible sheets with glue.
