Guangmai Technology's 3030 is mainly made of PCT material, because the PCT cost advantage is obvious when the power is 1W. Of course, there are EMC brackets to choose from, but it is not cost-effective when it is less than 1W.
At present, the LED package bracket is mainly composed of plastic, copper, and electroplating. The key to heat conduction is the material of the plastic. The main application materials are PPA, PCT, and EMC.
PCT materials are superior to the existing PPA in terms of high temperature endurance, high temperature and long-term yellowing, reflectivity, and UV irradiation. It can achieve incomparable color stability and low water absorption (about one thousandth) of other similar materials. It is used in the production of large outdoor LED screens and can achieve good environmental adaptability. In addition, the PCT material is made of ceramic fiber with a fiber content of about 20%. It has good weather resistance, UV resistance, low water absorption and molding shrinkage, and good dimensional stability.
The EMC stent has the characteristics of high heat resistance, UV resistance, high current flow, small size, and anti-yellowing characteristics, which brings new options for LED packaging plants that are pursuing continuous cost reduction. Both the LED packaging factories in Taiwan and the LED packaging factories in mainland China actively expanded EMC production capacity in 2013. Among them, the production capacity of land-based LED packaging factories has expanded rapidly.
