Study On High-Power Light Emitting Diode Device Package Technology And Process

Solid state lighting is a high brightness LED (light emitting diode) in the application to expand a new field. Over the years the human have been searching for and development of solid light source, along with the development of semiconductor light emitting material and manufacturing process improvements, the luminous efficiency and reliability improvement, application market from the signal display, indoor and outdoor decoration, mobile phone backlight application positive outdoor advertising screen, automotive lighting, large size LCD backlight, and even the general lighting the rapid expansion of the field, market dimensions expands ceaselessly, and our country is a power energy is relatively poor country. Therefore, promotion of semiconductor green lighting project in our country is very necessary.However, in view of the semiconductor lighting technology is not yet mature, semiconductor lighting source into the ordinary illumination field still remain time. To this end, the need for further semiconductor lighting technology research.Semiconductor lighting product performance and deciding factor is a chip and the package, which package technology on product performance, high reliability, plays a vital role in. Lighting package of semiconductor device is different from (?) traditional lighting source, must use the newer and higher encapsulation technology and reliability control means. Based on this understanding, This article from the high-power semiconductor lighting device package, starting with the basic principle of radiating, to packaging material selection and packaging technology as the ibothold, the practice of high brightness LED device packaging process, high brightness LED device large-scale production basis...
