The mobile phone camera is one of the important parts of the mobile phone. In the process of assembling mobile phone cameras, FPC is essential. Without the support of FPC, the camera of the mobile phone cannot take pictures and generate pictures. So what role does FPC play in the camera?
In the composition of the mobile phone camera, the FPC is the circuit connection part of the CMOS sensor. One end of the FPC can be connected to the gold wire of the CMOS sensor, and the other end can be connected to the mainboard of the mobile phone, thereby realizing a complete circuit. In the camera of the mobile phone, the functions of the FPC are as follows:
1. Provide electrical characteristics and play the role of electrical connection;
2. Provide mechanical properties to support the fixation and assembly of electronic components;
3. It can realize automatic mounting, welding and testing between integrated circuits and electronic components.
The FPC in the mobile phone camera must be tested in production, one is to verify whether the FPC performance is qualified, and the other is to verify whether the FPC quality is good. It is required that the FPC has no damage, no dirt, no wrinkles, no copper leakage and no warping corners at the hot pressing. In addition to testing the appearance, it is also necessary to test the thickness of the substrate, plug-in pinholes, resistance and capacitance parameters, etc. It is beneficial to improve the qualification rate of products, and can also improve the overall quality of the mobile phone camera and reduce the production cost.
Among the required test devices, the indispensable is the shrapnel microneedle module. Because of its thin and light body, it is a shrapnel-type design, which can adapt to the complex lines and small spacing inside the mobile phone, maintain a long-term connection, no PIN, continuous needle, and superior performance. When the mobile phone camera FPC is electrically connected, the shrapnel microneedle module can transmit current in the range of 1-50A. Overcurrent is stable, no current attenuation, stable connectivity and an average service life of more than 200k times, so it does not need to be replaced frequently, which can greatly improve the test efficiency of mobile phone camera FPC.
With the technological innovation of cameras, the development of the rear camera of mobile phones from dual to multi-camera not only meets the needs of users for high-quality and diverse photography, but also achieves more vivid and natural imaging effects. Because the market demand is increasing day by day, it also drives the growth of the usage of FPC.
