Jingtai Optoelectronics Zhang Zhennan: PCT materials have obvious application advantages

August 28, 2020

On April 11, after Guangzhou, Xiamen and Hangzhou, the Zhongshan Station, the fourth station of the 2014 China LED Lighting Supply Chain Good Product Tour Symposium hosted by Gaogong LED, was successfully concluded.

The rapid start-up of the global LED lighting market comes from the rapid application of disruptive technology and the optimal control of enterprise supply chain costs. The global competition in the Chinese market has brought several advances. The first is the globalization of supply chains, and the second is the rapid improvement of localized OEM/ODM capabilities.

For LED lighting companies, the era of simply price is not the foundation for the survival of excellent enterprises. The cost of channel development is getting higher and higher, and the homogenization of products is getting more and more serious. What should enterprises do? Where is the way out? Many companies are secretly improving the supply chain, segmenting the market and optimizing the product structure. What are the next three years? Is the supply chain.

This Zhongshan Station seminar once again invited Dr. Zhang Xiaofei, Chairman of Gaogong LED, Li Zhaohua, Deputy General Manager of Mingwei Electronics, Zhang Zhennan, R&D Manager of Jingtai Optoelectronics, Dong Pei, General Manager of Feitai Technology, and Lin Jiliang, General Manager of Mulinsen Lighting, etc. The theme of LED lighting industry, packaging new materials, new processes, selection of LED driver power, nano-graphene thermal materials and LED lighting application trends, market structure and other topics delivered a keynote speech.

As an important part of the LED lighting source, the lamp bead and the packaging industry in which it has been in the fast driving development stage of new materials and new processes have been in recent years.

At present, LED package brackets are mainly composed of plastic, copper and electroplating. The key to thermal conduction is to look at the material of plastics. The main application materials are PPA, PCT and EMC.

“PCT materials are superior to existing PPA in high temperature endurance, high temperature long-term yellowing, reflectivity, and UV irradiation. It can achieve unmatched color stability and low water absorption of other similar materials (one thousandth Left and right), used for large outdoor LED screen production, can achieve good environmental adaptability." Zhang Zhennan introduced, in addition, PCT material is added ceramic fiber, containing about 20% fiber, good weather resistance, UV resistance, lower Water absorption and molding shrinkage as well as good dimensional stability.

Zhang Zhennan believes that the PCT lamp bead products of Jingtai Optoelectronics are the most cost-effective, and the PCT 1W products are not exported to EMC 1W products through the LM-80 experiment. EMC products currently have an advantage over EMC. Recently, many manufacturers use it for TV backlighting, high-power lighting SMD LEDs, etc.
