Guide : For the current camera module market where competition and development co-exist, the change in processing mode has undoubtedly become the biggest test during the transition. At present, most domestic camera module factories still use traditional soldering and thermal welding. Welding process, efficiency and yield rate can not meet the needs of timely large orders. Then the necessity of the constant temperature laser soldering system as a welding heat source is increasingly reflected.
As a video input device, the camera was widely used in video conferencing, telemedicine, and real-time monitoring in the early stages of development. With the development of Internet technology, the network speed has continued to increase, and the imaging technology has matured, which has made the price of the camera Reduce to daily acceptable levels. According to statistical reports from professional research institutions, the output value of camera modules will reach US $ 15.9 billion in 2014, a year-on-year increase of 22.3%. Mobile devices such as mobile phones and tablet computers are the main force in this market. Among them, smart phones have accounted for more than 80% of camera module shipments. In addition, the fields of security monitoring, wearable electronics, and automotive cameras are also growing rapidly. Since these markets still have large profit margins, they are also some emerging markets that module manufacturers are striving to explore. .
For the current increasingly competitive mobile phone camera module market, the original domestic market was mainly occupied by local small and large module manufacturers, and terminal manufacturers were less involved, but now more and more manufacturers have joined this type of market. Companies including Japan, South Korea, and Taiwan are also stepping up their domestic market layout. For products positioned in different markets, as the overall module market price is gradually decreasing, most high-end modules increase value by improving product performance, and strive to keep it within a reasonable price range. The overall device has been miniaturized. , High integration, multifunctional development, the distance between devices and devices, devices and pads is getting smaller and smaller. As well as the increase in production efficiency and yield requirements of large-scale mass production, the problems brought by it have become sharper and sharper. The traditional processing mode can no longer meet the development needs at this stage. The design of new functions needs to be more advanced. Transformation of processing mode, most of the domestic camera module factories still use the traditional soldering iron and thermal compression welding process, because the soldering iron and thermal compression welding is a contact welding method, and due to the camera module welding The small points limit the precision of the welding head and fixture. In terms of efficiency and yield, it cannot meet the demand for timely large orders. Then the necessity of the laser as a welding heat source is increasingly reflected.
In addition, compared with large international manufacturers, the competitiveness of domestic manufacturers is particularly prominent in the realization of automation. Manufacturers must have standardization, and the first step in standardization is that manufacturers can make parts and components in products common. For example, VCM There are 9 to 10 parts in total. A large part of these parts can be shared, but sometimes because of specific customer requirements and requirements, all parts cannot be shared. In this case, manufacturers except parts In addition to public use, part of the modular public use is completed to achieve so-called standardization. Standardization is the lead in realizing automation. With the standardized production of modules, the role and advantages of manufacturers can be maximized, and the diversity, difficulty, and uniformity that can be achieved in production can be guaranteed. The purest non-contact laser processing mode with automatic production lines has gradually become a development trend.
It is imminent for camera companies to change their production models. Of course, the camera module products that have been asked are also challenges and opportunities in the transition period. Wuhan Bolink Technology Co., Ltd., aimed at mature manufacturers of precision laser soldering in China, follows the market development trend. As a constant temperature laser soldering system, it contributes to the development of the domestic camera module industry. The constant temperature laser soldering system is composed of a multi-axis servo module, a real-time temperature feedback system, a CCD coaxial positioning system, and a semiconductor laser. The intelligent soldering software independently developed by Boliontech supports the import of multiple format files. The original PID online temperature adjustment feedback system can effectively control constant temperature welding and ensure welding yield and precision. The constant temperature laser soldering system has a wide range of applications, can be applied to online production, and can also be processed independently.
