[0002] OTP is the acronym for One Time Programmable in English. It is a memory type of MCU, which means one-time programming. OTP mostly uses a fuse structure, and the programming process is an irreversible destructive activity. Compared with the eeprom used by traditional companies , OTP has the advantage of low price, which is very important in the increasingly competitive mobile phone market. In the application of camera modules, OTP has been used more and more in high-pixel cameras due to its low price and convenient and fast use. The application has played a great role in improving the quality of high-pixel cameras. For example, you can obtain very consistent imaging effects by storing Lens shading parameters, avoid color cast by storing AWB parameters, and quickly save AF positions by storing AF positions. Improve the speed and accuracy of module AF focusing, effectively manage the version of the product by storing the Module ID, and store the Lens ID to facilitate customers to distinguish between different module manufacturers and different lenses used, so as to facilitate their control of the product, but , because the OTP programming process is irreversible, with the development of technology, mobile phone modules, pixels, quality and technology upgrades are becoming more and more stringent, and the requirements for the camera module OTP burning process are also getting higher and higher. The traditional method A darkroom is required for OTP programming of camera modules, which requires particularly strict requirements on the occupied factory floor area and darkroom decoration, which increases the production cost of mobile phone camera OTP applications, and the darkroom programming itself has problems with the operating environment and efficiency of operators. Therefore, there is an urgent need to develop a fixture-type burning method that can improve the camera module OTP burning hardware environment and improve burning efficiency.

The invention discloses an OTP (one time programmable) burner for camera modules. Based on a using direction, the OTP burner comprises a box, a loading / ejecting mechanism and a plurality of burning test mainboards. The box is provided with a loading / ejecting hole. The loading / ejecting mechanism comprises a vertical board and a bottom board. The bottom board is capable of sliding relative to a bottom board of the box. The vertical board covers or opens the loading / ejecting hole. A support plate is further arranged on the bottom board. Camera modules to be burned are arranged above the support plate and are electrically connected with the burning test mainboards, a top board of the box is provided with holes with each corresponding one camera module to be burned, a stray light filter is arranged in each hole, and a DNP (Dai Nippon Printing) light source is arranged above the stray light filters. The OTP burner for camera modules need not be operated in darkrooms, operating environment for OTP burning of the camera modules can be improved greatly, efficiency and quality in OTP burning of the camera modules are increased, time, labor and hardware cost are reduced, and production cost is reduced greatly.
