Jian Yu Cang: "Bitterness and Music" of Aluminum Substrate

On May 7th, “2013 Zhongshan Lighting Quality Upgrade Strategy Conference” was successfully held in Xiaolan, Zhongshan. The conference attracted more than 400 business leaders.

The conference was jointly sponsored by Gaogong LED, Zhongshan Semiconductor Lighting Industry Association and Zhongshan Semiconductor Lighting Industry Technology Alliance. Zhongshan Science and Technology Bureau, Zhongshan Xiaolan Town People's Government as support unit, Philips Lumileds, Mulinsen Lighting, Mingwei Electronics, Confucian Electronics, Star Alliance Lighting, LED Lighting Expo Center, etc. are sponsors. It covers various key elements of enterprises, governments, business associations, high-end media, and exhibition platforms of regional industrial clusters.

Hong Ji Lighting General Manager Du Jifang, Pinshang Lighting Chairman Hong Ziang, Guangyang Lighting General Manager Chen Shaozhong, Xiaobailong Lighting Chairman Wang Yunlong, Ou Man Technology Lighting General Manager Li Xiaoping, Minguang Lighting General Manager Guo Huaguo, Shanghai Luyuan Lighting Standing Vice President Luo Quanxing, Ward Lighting General Manager Cai Xianghu, Yuzhiyuan Solar Technology Chairman Lei Zongping, Zhongshan Starlight Alliance Investment Co., Ltd. Zeng Shuneng, Guangbohui Managing Director Guo Xiu, Kyushu City General Manager Zhang Liqiang, Zhongshan Semiconductor Lighting Industry The delegation of the Association, Tu Qiaoling, and the Secretary of the Zhongshan Lighting Association, Mr. Decheng, and other 400 guests attended the meeting.


Jian Yu, general manager of Confucian Electronics, said that at present, the problems of domestic aluminum-based circuit boards are:

1. Confusion of the pressure resistance index of aluminum substrates. Including the confusion of breakdown voltage and arc effect; the contradiction between the whole lamp withstand voltage and aluminum substrate withstand voltage; the influence of circuit design and structural design on withstand voltage.

2. Uniform confusion of thermal conductivity test methods and test results. For example, laser scintillation test method; 5470 test method; thermal conductivity of dielectric layer and thermal conductivity of finished aluminum substrate.

3. The specification of aluminum-based copper clad laminates is not uniform. There are industry standards for CPCA; national standards; international standards.

4. The spoiler of the cottage. Cut corners, shoddy and shoddy.

The current industry situation is: from the design specifications, processing technology to acceptance criteria, there is no unified version, basically speaking, even if you buy me, I will sell it, you just buy it, I will not buy it. What quality reliability. For a time, the price of the products on the market was chaotic, causing the products to be mixed. The light source, power supply and aluminum substrate are the three core components of the whole lamp. The chaos of the aluminum substrate finally affects the finished LED lamp market.

Jian Yucang believes that the only way to get out of the confusion of aluminum substrates is to do the following. First, when there is no standard, it should be in line with the highest and best level of the industry; then the supplier and the buyer should specify the materials supplier; the supply and demand sides will accept the acceptance criteria and the designated authority to test Finally, the industry and the government issued corresponding regulations.

XLPE Insulated Electrical Cable For Rated Voltage 0.6/1kV

1. Product Standard

GB/T12706.1-2002, equivalent to IEC60502

2. Usage

This product is suitable for use in rated AC voltage (U0/U) 0.6/1kV system transmitting and distributing circuit.

3. Property for Use

It is far better than all property targets of PVC Insulated Power Cable and has overcome the shortcomings of physical and chemical cross-linkage, and completely reaches or surpasses GB and IEC technical property value.

The allowed max .cable conductor work temperature is 90℃;urgent excess work temperature is 130℃ for short circuit(5s), max. conductor temperature is 250℃.

The environmental temperature for laying cable should be not less than 0℃. If laying under 0℃, the cable should be preheated.

The cable bend radius for single core should be not less than 12 times of overall cable diameter; for multi-core cable, not less than 10 times of overall cable diameter.

The current-carrying capacity is large and not limited by drop during laying .
