5G drives the growth of mobile camera FPC? Analyzing the Role of FPC in Mobile Camera

The application scope of FPC in mobile phones includes components such as batteries, screens, cameras, side buttons, antennas, fingerprint modules, speakers, etc. Since the penetration of 5G communication technology, the number of internal parts in mobile phones has increased, and the number of 5G antennas has increased, further driving the growth of internal FPC usage in mobile phones. Since the commercialization of 5G, the usage of mobile FPC has increased by 15% -20%, and the area of mobile motherboards has also increased simultaneously.



In the composition of mobile phone cameras, FPC is the circuit connection part of CMOS sensors. FPC can be connected to the gold wire of CMOS sensors at one end, and the other end can be connected to the mobile phone motherboard to achieve a complete electrical circuit. The support of FPC is indispensable for mobile phone cameras to take photos and generate images. In mobile phone cameras, the functions of FPC include: 1. providing electrical characteristics and serving as an electrical connection; 2. Provide mechanical performance to support the fixation and assembly of electronic components; 3. Able to achieve automatic assembly, soldering, and testing between integrated circuits and electronic components.



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



The mobile phone camera FPC must have no damage, dirt, wrinkles, copper leakage, and no warping at the hot pressing point on its appearance. It is also required that the FPC must have no open or short circuits. For mobile phone camera FPC, in addition to appearance, it is also necessary to use instruments to measure substrate thickness, plug-in pinholes, resistance, capacitance parameters, as well as short circuits, open circuits, etc. This is beneficial for improving the qualification rate of mobile phone camera FPC, improving the overall quality of mobile phone cameras, and reducing production costs.



The FPC for mobile phone cameras is an indispensable component of the instruments used, which is the elastic micro needle module. Due to its lightweight body and elastic design, it can adapt to the complex circuits and small gaps inside the phone. It can handle pitch values between 0.15mm-0.4mm, maintain long-term connectivity, do not block PINs, and continuously needle, with superior performance. When the mobile phone camera FPC is electrically connected, the spring micro needle module can transmit current within the range of 1-50A, with stable overcurrent and no current attenuation. It has stable connectivity and an average service life of more than 20w times, so there is no need to replace it frequently, which can greatly improve the efficiency of the mobile phone camera FPC.
