Function of FPC in Mobile Camera

The application scope of FPC in mobile phones covers batteries, screens, cameras, side buttons, antennas, fingerprint modules, speakers and other components. Since the penetration of 5G communication technology, the number of internal parts of mobile phones has increased, and the number of 5G antennas has increased, further driving the growth of the use of FPC in mobile phones. Since 5G became commercially available, the usage of mobile phone FPC has increased by 15% – 20%, and the area of mobile phone motherboard has also increased simultaneously.

In the composition of mobile phone camera, FPC is the circuit connection part of CMOS sensor. One end of FPC can be connected to the gold wire of CMOS sensor, and the other end is connected to the mobile phone motherboard to achieve a complete electrical circuit. The mobile camera can’t take photos and generate pictures without the support of FPC. In the mobile camera, FPC has the following functions:

  1. Provide electrical characteristics for electrical connection;
  2. Provide mechanical properties to support the fixation and assembly of electronic components;
  3. It can realize automatic mounting, soldering and detection between integrated circuits and electronic components.

The development of mobile phone rear camera from dual camera to multi camera represents the innovation of camera technology, which not only meets users’ needs for high-quality and diversified photography, but also achieves more vivid and natural imaging effects, and also becomes the focus of competition among mobile phone manufacturers in terms of differentiation. Under the 5G network layout, the further promotion of mobile phone multi camera mode will drive the growth of the use of FPC. Mobile phone camera FPC must be tested in production, first to verify whether the performance is qualified, and second to verify whether the quality is damaged.
