Daewon Innost Makes Breakthroughs on Silicon COB LED Substrate

Daewon Innost has made a breakthrough on its Glaxum LED Array family of chip on board (COB) modules, which it claims to achieve the LED industry’s best thermal dissipation performance. The proprietary Nano-Pore Silicon Substrate (NPSS) technology developed by Daewon Innost led to thermal impedance of 0.41°C/W. Daewon Innost’s NPSS is created by applying semiconductor lithography to silicon wafers, allowing for 50µm-pitch interconnection between gallium nitride (GaN) LED chips; conventional metal-core printed circuit boards (MC...

Fundamental Summary of LED SiC Substrate

Silicon carbide is also called "emery powder" or "refractory sand." The usual manufacturing process of SiC is to combine silica sand, tar (or coke), woodchip (and salt when manufacturing green SiC) and other materials in an electric resistance furnace at a high temperature. Silicon carbide is usually divided into two categories, the black SiC and the green SiC, both having a hexagonal crystal structure, a density of 3.2 -3.25g/cm³ and microhardness of 2840-3320kg/mm2.
