As we all know, as the demand for high-order camera products continues to rise in the intelligent terminal market, the yield and quality requirements of high-order camera products are relatively high, which is very helpless for most module manufacturers, making the domestic AA equipment industry often under the control of others. ". Shenzhen Zhongke Jinggong Technology Co., Ltd., a domestic high-end AA equipment manufacturer, is about to break this market pattern.

Perfect optical active focusing

"In the camera packaging process, AA equipment has high-precision control to adjust the relative position of modules and lens tilt, effectively improving the consistency of camera products. In terms of active alignment technology, AA equipment used in the AA manufacturing process improves the calibration accuracy of products by reducing the assembly tolerance of the entire module, thus reducing production time, improving production yield and increasing mass production rate." Wang Huamao, general manager of Zhongke Seiko, said. Zhongke Jinggong's AA equipment includes DA process, DA Tilt control, WB gold wire process, and bracket (IR Glass) assembly. Its AA process is a perfect substitute (LHA+Auto Focus) for the two major processes, perfectly realizing optical active focusing, and solving the problems of precise focusing, yield, price, etc. for camera module manufacturers.

Zhongke Jinggong AA equipment passes through 6-DOF XYZ three-axis translation and αβγ The adjustment of three-axis rotation compensates the tilt and offset of optical axis to achieve the best image quality. To put it simply, it is to make the precision control of 6 degrees of freedom within 10M at the same time, so as to achieve perfect active focusing. This precision is equivalent to one tenth of the hair, which is also the most difficult problem in technology. It perfectly solves the pain point of camera module manufacturers. Compared with the accuracy of equipment in the current market, it can almost be called revolutionary innovation.

High yield and high return

In recent years, Zhongke Jinggong has been committed to vigorously developing relevant technologies based on the perfect and effective solutions provided by camera module manufacturers and striving to make the existing technologies better and stronger. Huamao said to the author, "Many equipment manufacturers purchase others' patented technologies from processes, algorithms and production processes, while Zhongke Jinggong is different from it. From algorithms to solutions, the entire process flow uses unique technologies." The author learned that up to now, there have been more than 20 patents of Zhongke Seiko cameras for AA.

"The yield of Zhongke Jinggong's AA equipment is 1% - 1.5% higher than that of Hong Kong's more famous AA equipment manufacturers, and the camera module manufacturers can save at least 100000 yuan in one month by increasing the yield by one point." Huang Hui, R&D director of Zhongke Jinggong, said.

"Customers do not need LHA and the final auto focusing link when they buy our equipment, which greatly saves manpower and financial resources. In fact, Zhongke Jinggong has helped the current module manufacturers to improve their production capacity, and has also achieved a level comparable to that of Korean AA equipment manufacturers." Wang Huamao added.

Undoubtedly, this will cause revolutionary shock to the module manufacturers, the direct customers of the manufacturers.
