Module Rigid-Flex circuit board

The Application of Rigid-Flex Circuit Board

1. Industrial use

Industrial applications include Rigid-Flex circuit boards used in industry, military, and medical applications. Most industrial components require characteristics such as precision, safety, and non vulnerability to damage. Therefore, the characteristics required for soft and hard boards are: high reliability, high precision, low impedance loss, complete signal transmission quality, and durability. But due to the high complexity of the manufacturing process, the output is small and the unit price is quite high.

2. Mobile phone

The application of the Rigid-Flex circuit board in mobile phones commonly includes the Hinge, Camera Module, Keypad, and RF Module of foldable phones.

The advantages of using the Rigid-Flex circuit board on mobile phones.

2.1. It is the integration of parts in mobile phones

2.2. It is a consideration of signal transmission volume. At present, mobile phone products use the Rigid-Flex circuit board to replace the original combination of two connectors and FPC. Its greatest significance in the product is to increase the durability and long-term reliability of the mobile phone's folding point. Therefore, the Rigid-Flex circuit board is highly valued for its high product stability. On the other hand, due to the popularity of camera phones and the integration of multimedia and IT functions within phones, the internal signal transmission volume of mobile phones has increased, resulting in a demand for modularity.

3. Consumer electronics products

In consumer products, DSC and DV are representative examples of the development of Rigid-Flex PCB, which can be discussed in terms of performance and structure.

3.1. In terms of performance, the Rigid-Flex circuit board can connect different PCB hard boards and components in a three-dimensional manner. Therefore, under the same circuit density, it can increase the total usage area of the PCB, relatively improve its circuit carrying capacity, and reduce the signal transmission limit and assembly error rate of the contacts.

3.2. Due to the lightweight and thin nature of the Rigid-Flex circuit board, it can bend wiring, which is of substantial benefit in reducing volume and weight.

4. Automobile

The use of the Rigid-Flex circuit board in automobiles commonly includes buttons for connecting the steering wheel to the motherboard, connections between the vehicle's video system screen and control panel, operation connections for audio or function keys on side doors, reverse radar imaging system, sensors, vehicle communication system, satellite navigation, PCB for connecting the rear seat control panel and front-end controller, and external detection system.
