Recently, Huizhou Dayawan Yongsheng Electronic Industry Co., Ltd. invested a large amount of capital and technical strength to study the key technologies of eutectic welding equipment for a long time, realizing rapid temperature rise, rapid cooling, flexible temperature curve stepwise temperature control, and reaching ultra-low voids. The requirements of the eutectic process technology.
The technology solves the problems of high-speed and high-precision identification and positioning of LED chips and ceramic substrates, vision-based modeling and high-precision position/force control in eutectic processes, and step-type pulse temperature control systems based on specific temperature curves during welding. Technology, and made major breakthroughs in the main technical processes such as chip supply device, visual positioning device, flux supply device, bracket supply device, bracket tray, welding finished product storage device and equipment welding process, and the results have been submitted to the State Intellectual Property Office. Apply for a patent and obtain approval and authorization, and take the lead in realizing the integration of eutectic and welding in China.
The use of Yongzhen electronic eutectic technology will increase the heat dissipation efficiency of the high-power LED device chip substrate and substrate connection point by 5-15 times, control the junction temperature within 65 degrees, the eutectic void ratio is less than 15%, and the welding strength is greater than 7KG. After the chip is soldered, the VF value is less than 0.08 volts. After testing by an authoritative organization, the eutectic quality has reached the international advanced level of similar products.
The technology and process have been recognized by the famous Japanese lighting manufacturers USHIO (Oxtail) and Osram Lighting. The two parties have established a cooperative relationship to produce LED lighting products, and will also produce high-reliability high-quality lighting products for domestic users.
