Advantages and disadvantages of flexible circuit board

1. Advantages:
(1) It can be freely bent, wound, folded, arranged according to the space layout requirements, and moved and expanded in three-dimensional space, so as to achieve the integration of component assembly and wire connection;
(2) Using FPC can greatly reduce the volume and weight of electronic products;
(3) FPC also has the advantages of good heat dissipation and weldability, easy assembly and low comprehensive cost. The design of soft and hard combination also makes up for the slight deficiency of flexible substrate in the bearing capacity of components to a certain extent.
2. Disadvantages:
(1) High one-time initial cost
Because flexible PCBs are designed and manufactured for special applications, the initial cost of circuit design, wiring and photographic plates is high. Unless there is a special need to apply soft PCB, it is usually better not to use it in a small amount of applications.
(2) It is difficult to change and repair soft PCB
Once the soft PCB is made, it must be changed from the base drawing or the prepared photo program, so it is not easy to change. Its surface is covered with a protective film, which should be removed before repair and restored after repair, which is a relatively difficult work.
(3) Size is limited
Soft PCB is usually manufactured by batch process when it is not popular, so it cannot be made very long and wide due to the size of production equipment.
(4) Easy to damage due to improper operation
Improper operation by the assembly and connection personnel may easily cause damage to the soft circuit. Its soldering and rework need to be operated by trained personnel
