1、 FPC board

FPC board is a flexible circuit board composed of multi-layer thin film materials that can be bent and folded, suitable for electronic products that require bending. FPC boards are often used in fields such as mobile devices, medical devices, automotive electronics, and aerospace. FPC boards generally use metal foil as a conductive layer and are manufactured through processes such as chemical corrosion or laser cutting.

The FPC board has the following characteristics:

Flexibility: FPC boards can be bent within a certain range, suitable for electronic products that require bending.

Good conductivity: The FPC board uses metal foil as the conductive layer, which has excellent conductivity.

Lightweight: FPC boards are made of thin film materials, making the entire circuit board very lightweight.

Flexible layout: FPC boards can freely arrange components and wires in three-dimensional space, with flexible layout.

2、 PCB

PCB is a rigid circuit board composed of one or more conductive and insulating layers, usually made of glass fiber reinforced material. PCB boards are suitable for electronic products that require high stability and performance. The manufacturing process of PCB boards is relatively complex, usually requiring multiple processes such as chemical corrosion, gold plating, drilling, and copper coating.

The PCB board has the following characteristics:

Rigidity: The PCB board is made of glass fiber reinforced material, and the entire circuit board is very hard.

Good conductivity: The PCB board uses copper foil as the conductive layer, which has excellent conductivity.

Flexible layout: PCB boards can freely arrange components and wires in a two-dimensional space, resulting in flexible layout.

Wide application range: PCB boards are suitable for various electronic products that require high stability and performance.

3、 The difference between FPC board and PCB

Material difference: FPC board is made of flexible film material, while PCB board is made of rigid glass fiber reinforced material.

Different bending abilities: FPC boards can be bent within a certain range, while PCB boards are rigid and cannot be bent.

Different manufacturing processes: The manufacturing process of FPC boards is relatively simple, usually requiring only one chemical corrosion to complete, while the manufacturing process of PCB boards is relatively complex, requiring multiple processes such as chemical corrosion, gold plating, drilling, and copper coating.

Different application ranges: FPC boards are suitable for electronic products that require bending, while PCB boards are suitable for various electronic products that require high stability and performance.

Overall, FPC and PCB boards have their own advantages and disadvantages, and appropriate circuit board types should be selected based on different application scenarios. When designing a circuit, it is necessary to consider factors such as circuit performance requirements, manufacturing costs, and production cycles, and select the most suitable circuit board type after comprehensive consideration.
