Company information
FUJIAN HUAQING ELECTRONIC MATERIAL TECHNOLOGY CO., LTD
Founded in 2004, with a sum investment of 80 million RMB, registered capital 40Million RMB, Fujian Huaqing Electronic Material Technology Co., Ltd. is a high-tech enterprise co-founded by Xin Cheng(Hongkong) Holdings Co., Ltd. and Jinjiang Kechuang Co., Ltd. Huaqing is based on the core technology supplied by the state key laboratory of new ceramics and fine processing in Tsinghua University.
As China's first company to accomplish scale production via tape-casting manufacturing processing, Huaqing owns a whole complete set of manufacturing advanced and sophisticated equipment and inspection instruments imported from Japan, the US, and other developed countries for our electronic ceramic. Our tape-casting manufacturing processing and technics for AlN & Al2O3 ceramic have their originality and advance in tape-casting wet & furnish and low-cost sintering.
Huaqing's AlN & Al2O3 ceramic products have high thermal conductivity, low dielectric constant, good dissipation factor, and excellent mechanical properties compared with the other factories in the industry. AlN & Al2O3 ceramic are widely used in HBLED, opto-communication, IGBT, power devices, TEC, and other high-end applications.
