FPC soft hard combination board, also known as Rigid Flex Printed Circuit Board, is a composite circuit board that combines a flexible printed circuit board (FPC) with a rigid printed circuit board (PCB) through specific processes such as compression bonding. This design combines the flexibility of FPC and the stability of PCB, enabling complex circuit layouts in limited space while meeting the dual requirements of mechanical strength and flexibility for equipment.
FPC soft hard junction board is usually composed of multiple layers of structure, including rigid PCB part and flexible FPC part. The hard part provides stable support and installation platform for fixing electronic components; The flexible part is used to connect different components, allowing for bending and folding during assembly. This combination not only improves the space utilization of the circuit board, but also enhances its reliability in complex environments. The production process of FPC soft hard combination board is relatively complex, requiring both FPC and PCB production equipment. During the production process, the FPC and PCB parts are first manufactured separately, and then they are combined together through a pressing process. This process requires extremely high precision and quality control to ensure good bonding between different materials and stability of electrical performance.
The application scenarios of FPC soft hard combination board are very wide, covering multiple fields such as consumer electronics, automotive electronics, medical equipment, aerospace, etc. In the field of consumer electronics, such as high-end smartphones, tablets, and smart wearables, FPC soft and hard combination boards are used to connect components such as display screens, cameras, and sensors, providing stable data transmission and flexible assembly methods. In automotive electronics, it is used for the electronic systems of automobiles, such as instrument panels, center consoles, and autonomous driving sensors, which can withstand vibrations during vehicle operation while implementing complex wiring. In medical devices, the flexibility of FPC soft and hard bonding boards enables them to fit the curves of the human body and provide a comfortable wearing experience. In the aerospace field, it is used in electronic systems for aircraft and satellites to ensure reliability and stability in extreme environments.
The advantage of FPC soft hard combination board lies in its ability to save space, improve performance, and enhance flexibility. However, its production difficulty is high and the yield rate is low, resulting in higher costs. In addition, the production cycle is relatively long, and the requirements for manufacturing processes and equipment are also high. With its unique combination of rigidity and flexibility, it plays an important role in modern electronic devices. With the continuous advancement of technology, its application scope will further expand, providing more possibilities for the design and manufacturing of electronic products.
