Advantages and disadvantages of flexible PCB circuit boards

Advantages and disadvantages of flexible PCB circuit boards

1. Advantages:
(1) It can be freely bent, rolled and folded, and can be arbitrarily arranged according to the requirements of spatial layout, and can be freely moved and retracted in three-dimensional space to achieve the integration of component assembly and wire connection;
(2) The use of FPC can greatly reduce the volume and weight of electronic products;
(3) FPC also has the advantages of good heat dissipation and solderability, easy assembly, and low comprehensive cost. The combination of soft and hard design also makes up for the slight insufficiency of the flexible substrate in the component carrying capacity.
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 photolithography is high. Unless there is a special need to apply a flexible PCB, usually it is best not to use it in small applications.
(2) It is difficult to change and repair soft PCB
Once the flexible PCB is made, it must be started from the basemap or the programmed light-drawing program, so it is not easy to change. Its surface is covered with a protective film, which must be removed before repair and restored after repair. This is a relatively difficult task.
(3) Restricted size
Flexible PCBs are generally manufactured in batch processes when they are not yet widespread, so they are limited by the size of production equipment and cannot be made very long and wide.
(4) Improper operation and easy to damage
Improper installation of personnel can easily cause damage to the flexible circuit, and its soldering and rework require trained personnel to operate.
