The eutectic/coating process combined with thin film ceramic heat dissipation substrate is bound to greatly improve the LED luminous power and product life. In recent years, due to the development of aluminum substrate, the heat dissipation of system circuit board is gradually improved, and even the flexible circuit board is gradually developed. On the other hand, LED grain substrate is also gradually towards the direction of reducing its thermal resistance. How to reduce the thermal resistance of LED crystal ceramic heat dissipation substrate is the most important topic to improve LED luminous efficiency. According to the manufacturing method of its circuit, it can be divided into thick film ceramic substrate, low temperature co-fired multilayer ceramic substrate and thin film ceramic substrate, which are described as follows.
