Flexible circuit assembly is a type of PCB, also known as a "flexible board.". FPC is made of flexible substrates such as polyimide or polyester film, which has the advantages of high wiring density, light weight, thin thickness, bendability, and high flexibility. It can withstand millions of times of dynamic bending without damaging the wire and can move and expand arbitrarily according to the requirements of the spatial layout to achieve three-dimensional assembly and the integration of component assembly and wire connection, which has incomparable advantages over other types of circuit boards.
Examples of applications for multilayer FPC circuit boards
1. Mobile phone: flexible circuit board, light weight, thin thickness. It can effectively save the volume of the product and easily connect the battery, microphone, and buttons.
2. Computer and LCD screen: the use of flexible circuit board integrated circuit configuration, as well as thin thickness. Convert digital signals into images and present them on LCD screens.
3. CD Walkman: The three-dimensional assembly characteristics and thin thickness of the flexible circuit board turn the huge CD into a good companion to carry around;
4. Disk drive: Whether it is a hard disk or a floppy disk, it relies heavily on the high flexibility of FPC and the ultra-thin thickness of 0.1 mm to complete fast reading data, whether it is a PC or NOTEBOOK;
The difference between FPC and PCB
FPC (Flexible Printed Circuit) board and PCB (Printed Circuit Board) are two common types of circuit boards, and they are both essential components in electronic devices.
1. FPC board
A FPC board is a flexible circuit board that consists of multiple layers of thin film material that can be bent and folded, which is suitable for electronic products that need to be bent. FPC boards are commonly used in mobile devices, medical equipment, automotive electronics, aerospace and other fields. FPC boards generally use metal foil as a conductive layer and are manufactured through processes such as chemical corrosion or laser cutting.
The flex PCB board has the following characteristics:
Bendable: The FPC board can be bent within a certain range, which is suitable for electronic products that need to be bent.
Good conductivity: The FPC board uses metal foil as the conductive layer, which has excellent conductivity.
Light weight: The FPC board is made of thin film material, and the whole circuit board is very lightweight.
Flexible layout: The FPC board can freely arrange components and wires in a three-dimensional space, and the layout is flexible
.
2.PCB
A PCB is a rigid circuit board consisting of one or more layers of conductive and insulating layers, usually made of glass fibre reinforced material. PCB boards are suitable for electronic products that require high stability and high performance. The manufacturing process of PCB boards is complex, and it often requires multiple processes such as chemical corrosion, gold plating, drilling, and copper pouring.
The PCB board has the following characteristics:
Rigidity: The PCB board is made of glass fibre reinforced material, and the entire circuit board is very hard.
Good conductivity: The PCB board uses copper foil as the conductive layer, and the conductivity is excellent.
Flexible layout: The PCB board can freely arrange components and wires in a two-dimensional space, and the layout is flexible.
Wide range of applications: PCB boards are suitable for a variety of electronic products that require high stability and high performance.
3. The difference between FPC board and PCB
The materials are different: the FPC board is made of flexible thin film material, while the PCB board is made of rigid glass fibre reinforced material.
The bending capacity is different: the FPC board can be bent within a certain range, while the PCB board is rigid and cannot be bent.
The manufacturing process is different: the manufacturing process of FPC board is relatively simple, and usually only needs to be chemically etched once, while the manufacturing process of PCB board is more complex, requiring multiple processes such as chemical corrosion, gold plating, drilling, and copper pouring.
The scope of application is different: flex PCB board is suitable for electronic products that need to be bent, while PCB board is suitable for various electronic products that require high stability and high performance.
In general, FPC boards and PCB boards have their own advantages and disadvantages, and the appropriate board type should be selected according to different application scenarios. When designing circuits, it is necessary to consider the performance requirements of the circuit, manufacturing costs, production cycles and other factors, and select the most suitable circuit board type after comprehensive consideration.
