advantage:

(1) It can be freely bent, wound, and folded, and can be arbitrarily organized according to the requirements of spatial layout, and can move freely and elastically in three-dimensional space, thereby realizing the integration of component installation and wiring;

(2) The use of FPC can greatly reduce the volume and weight of electronic products;

(3) FPC also has the advantages of excellent heat dissipation and solderability, easy assembly and connection, and low cost. The design of the combination of soft and hard also makes up for the slight deficiency of the flexible substrate in the component carrying capacity to a certain extent. .

shortcoming:

(1) High one-time initial cost

Because flex PCBs are designed and manufactured for special applications, the initial circuit design, wiring, and photographic boards require higher costs. Unless there is a special need to use a flexible PCB, it is usually best not to use it in small quantities.

(2) Difficulty in replacement and maintenance of flexible PCB

Once the flexible PCB is made, it must be changed from the base map or the compiled light drawing program, which is not easy to change. The surface is covered with a protective film, which must be removed before repair, and it is difficult to restore after repair.

(3) Limited size

When flexible PCBs are not yet popular, they are generally mass-produced, so limited by the size of the production equipment, they cannot be made very long and wide.
