rigid flex pcb manufacturer Flex PCB FPC consumer electronic factory price OEM ODM 1oz

Flexible PCB is also called flexible printed circuit boards or FPCB. Compared with ordinary hard resin circuit boards, the flexible circuit board has the advantages of high wiring density, lightweight, thin thickness, less wiring space limitation, and high flexibility.

It adapts to the needs of today's electronic products towards the direction of high density and high reliability, miniaturization and lightweight. Meanwhile, flex PCB also meets the strict economic requirements and the need for market and technology competition.

• Advantages of soft and hard combination boards compared to general PCBs：

1. Lightweight

2. Thin interlayer

3. Short transmission path
4. Small conduction aperture
5. Low noise and high reliability

• Advantages of soft and hard combination boards compared to hard boards:

1. Flexible and flexible, capable of three-dimensional wiring, changing shape            according to space limitations

2. High and low temperature resistance, flame resistance

3. Foldable without affecting signal transmission function

4. It can prevent static interference

5. Stable chemical changes, stability, and high reliability

6. It is beneficial for the design of related products, reducing assembly time and        errors, and improving the service life of related products

7. Reduce the volume of application products, significantly reduce weight,                  increase functionality, and reduce costs

Application of Soft and Hard Combination Board
1. Industrial use - Industrial use includes soft and hard boards used in industrial, 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. The application of soft and hard boards in mobile phones commonly includes the Hinge, Camera Module, Keypad, and RF Module of foldable phones. The advantages of using soft and hard boards in mobile phones are the integration of components in the phone and the consideration of signal transmission capacity. At present, mobile phone products use soft and hard boards to replace the original combination of two connectors and a soft board. Its greatest significance in the product is to increase the durability and long-term reliability of mobile phone folding points. Therefore, soft and hard boards are highly valued due to their high product stability. On the other hand, due to the popularity of camera phones and the integration of multimedia and IT functions inside the phone, the internal signal transmission volume of the phone has increased, Modular requirements arise accordingly.

3. Consumer Electronics - In consumer products, DSC and DV are representative of the development of soft and hard boards, and can be discussed on two main axes: performance and structure. In terms of performance, soft and hard boards can connect different PCB hard boards and components in a three-dimensional manner. Therefore, under the same circuit density, the total usage area of the PCB can be increased, which can relatively increase its circuit carrying capacity and reduce the signal transmission limit and assembly error rate of the contacts. On the other hand, due to the lightweight and thin nature of soft and hard boards, they can bend wiring, which is essentially beneficial for reducing volume and weight.

4. Automobile - The use of soft and hard boards in automobiles, commonly including buttons for connecting the steering wheel to the motherboard, connection between the vehicle's video system screen and control panel, operation connection of audio or function keys on side doors, reverse radar imaging system, sensors (including air quality, temperature and humidity, special gas regulation, etc.), vehicle communication system, satellite navigation, rear seat control panel, and front-end controller connection board External detection system and other purposes.
