Recently, Guoxing Optoelectronics (002449) R&D team announced that it has once again made a major breakthrough in the field of high-power LED packaging technology, and successfully developed a mass production eutectic process technology.
The eutectic process is an advanced process technology for eutectic soldering of high-brightness LED chips on a substrate or a support. Instead of the conventional insulating glue or silver paste, the thermal resistance of the device can be reduced and the reliability of the device can be improved. According to the high-tech LED reporter, the eutectic process technology has been mastered by foreign LED companies such as Cree, Lumileds, Osram, etc., and Guoxing Optoelectronics has made breakthroughs in eutectic process technology, once again enhancing the domestic packaging manufacturers in the field of LED packaging technology. Core competitiveness.
The principle of the eutectic process is to use a plurality of metals to melt at a eutectic temperature to form a eutectic alloy, thereby soldering the LED chip to the substrate or the support. Since the beginning of 2011, Guoxing Optoelectronics has invested a large amount of capital, equipment and research and development strength. Through continuous process development and improvement, the eutectic void rate of LED chips has been successfully met to meet the industrialization requirements, and the eutectic quality has reached the international advanced level. High-power LED devices using eutectic process can meet the requirements of more severe use environments, and have broad application space in indoor lighting, outdoor lighting, and automotive lighting.

Absolute rotary Encoder measure actual position by generating unique digital codes or bits (instead of pulses) that represent the encoder`s actual position. Single turn absolute encoders output codes that are repeated every full revolution and do not output data to indicate how many revolutions have been made. Multi-turn absolute encoders output a unique code for each shaft position through every rotation, up to 4096 revolutions. Unlike incremental encoders, absolute encoders will retain correct position even if power fails without homing at startup.
