Differences between rigid PCB and flexible PCB

Flexible circuit board is made of polyimide or polyester film. Its board wiring density is high. Compared with rigid PCB, FPC is thin, smaller, and shorter, which reduces the volume of device assembly and allows device assembly to assemble more devices to achieve more functions. Under the same current carrying capacity, its weight can be reduced by about 60-70% compared with that of wire and cable, and compared with that of rigid PCB, its weight is reduced a lot, and its application scope is wider.

2. Cost of circuit board

Although circuit boards are very common now, the initial price of flexible circuit boards is still higher than that of hard boards. Because flexible boards are special and the manufacturing process is complex, the cost of circuit design, screen printing and flooring of circuit boards is higher than that of conventional boards. Therefore, generally there is no special need to use this kind of board.

3. Characteristics of flexible circuit board

1. Short time

All circuits on the board have been configured, saving a lot of assembly time

2. Small size

It reduces the volume of the product and is suitable for the installation of some high-end electronic products

3. Light weight

Disadvantages of circuit board

1. Not easy to repair

It is easy for the staff to cause damage to the line during operation, but it is difficult to repair. Once the production is successful, if problems are found, the engineering procedure must be started to change, so the workers on duty need to receive professional training

2. The size of the plate is limited

Because the production of circuit boards is not easy, many small and medium-sized enterprises are not very proficient in technology, and the manufacturing method usually used is relatively traditional, but also limited by the production equipment, so they can not do very long and wide
