Disadvantages of flexible PCB boards

1. High one-time initial cost: Since the flexible PCB is designed and manufactured for special applications, the initial circuit design, wiring and photographic masters require higher costs. Unless there is a special need to apply a flexible PCB, it is usually better not to use it in a small amount of application;

2. It is difficult to change and repair the flexible PCB: once the flexible PCB is made, it must be changed from the base map or the programmed light drawing program, so it is not easy to change. The surface is covered with a protective film, which must be removed before repair and restored after repair, which is a relatively difficult task;

3. Size is restricted: Flexible PCBs are usually manufactured by batch method when it is not yet common. Therefore, due to the size of production equipment, they cannot be made very long and wide;

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