Considerations for heat dissipation design in camera module factories

In recent years, with the rapid development of science and technology, due to market demand, the performance of camera sensor modules, camera module pixels, and the power consumption of camera sensors have become increasingly high, making their heat dissipation a challenge. The heat dissipation design of the camera module has a certain impact on the effectiveness of the camera. When the temperature is too high, there will be obvious noise in the dark, and some may even have color distortion such as images turning red; Recently, I encountered two customer feedback issues with the temperature of the camera module: one was USB 200W+500W. Due to its small structure, it was designed as a 4-layer board with components arranged on two sides, and the aging test lasted for half an hour

Camera Module Market | Intense Competition among Camera Module Manufacturers

The camera industry generally includes camera module lenses, image sensors, voice coil motors, module packaging, etc. Among them, image sensors are mainly CMOS, so they are also known as CMOS camera modules (CCMs). From the perspective of the entire industry chain, CMOS is the most profitable fine molecule industry, with a leading gross profit margin of 45% -50%, while optical lenses have the strongest profitability, with a leading gross profit margin of nearly 70% for large vertical light. The module (sealing test) end is located in the middle and downstream of the industry chain, with a relatively low entry threshold. Most domestic enterprises are engaged in camera module business, with a gross profit margin of about 10% lower.

The arrival of the 5G era is driving the development of camera module manufacturers and camera module manufacturers

With the high performance of smartphone cameras and the popularization of the next-generation communication standard "5G", the industry related to sensors will continue to grow. The arrival of the 5G era is driving the development of camera module manufacturers and camera module manufacturers. Sony, the world's largest market share in image sensors, is increasing its offensive investment. According to the Nihon Keizai Shimbun, Sony will invest 100 billion yen (about 6.5 billion yuan) in Nagasaki, Japan, to build a new semiconductor image sensor factory for smart phone cameras and other equipment. Clearly driving the development of camera module manufacturers.

Working principle of camera module

The camera module is a complex system that integrates optics, mechanics, electrical, software, and hardware. The production process requires high levels of cooperation and technical mastery in each process part. Below, we will briefly introduce the principle and process of this module. The light captured by the camera module passes through the lens and then projects the generated optical image onto the image sensor. The optical signal of an optical image is converted into an electrical signal by a photodiode. At this point, the obtained electrical signal is an analog signal, which is then converted into a digital signal through an analog-to-digital conversion circuit (A/D), and the signal is initially processed and output. The data obtained at this time is the RAW number
