Disadvantages of Flexible PCB

Disadvantages of Flexible PCB:

1. High One-Time Initial Cost

Because flexible PCBs are designed and manufactured for special applications, the initial circuit design, wiring, and photographic negatives are expensive. Unless there is a special need to apply a flexible PCB, it is usually best not to use it in a small amount of applications.

2. It is difficult to change and repair flexible PCBs

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

3. Size is Limited

Flexible PCBs are usually manufactured by batch process when they are not yet common. Therefore, due to the limitation of the size of production equipment, they cannot be made very long and wide.

4. Improper operation is easy to damage

Improper operation of the installation and connection can easily cause damage to the flexible circuit, and its soldering and rework need to be operated by trained personnel.
