The difference between rigid PCB board and flexible circuit board

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



2. Cost of circuit boards



Although circuit boards are now very common, the initial price of flexible circuit boards is still higher than that of hard boards. Due to the special nature of flexible boards and the complex manufacturing process, the cost of circuit design, screen printing, and flooring for circuit boards is higher than that of conventional boards. So there are generally no special needs and this type of board is not used.



3. Characteristics of flexible circuit boards



1. Short time



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



2. Small size



Reduced product volume, suitable for installation of some high-end electronic products



3. Lightweight

Disadvantages of circuit boards



1. Not easy to repair



It is easy for workers to cause damage to the circuit during operation, but repairing it is difficult because once the production is successful, if problems are found and changes are made, they must start as engineering procedures. Therefore, workers on duty need to undergo professional training



2. The size of the board is limited



Because the production of circuit boards is not an easy task, many small and medium-sized enterprises' process technology is not very sophisticated, and the manufacturing method usually used is relatively traditional, but also limited by production equipment, which cannot be made very long and wide
