On September 6, 2011, APT Electronics Ltd., a leading brand of high-brightness LED integrated chips, held a grand launch conference at the Shenzhen Convention and Exhibition Center, and released four new products.
At the meeting, Dr. Xiao Guowei, the managing director of Jingke Electronics, first introduced the development history, technical advantages and future development trend of Jingke Electronics to the participants. Then Dr. Chen Haiying, Director of Application Development of Jingke Electronics, introduced this new series. The characteristics of the company were explained in detail. At the meeting, a number of industry celebrities also delivered wonderful speeches, including international brand lighting manufacturers and international brand power suppliers. Their valuable opinions and professional knowledge helped the LED industry to understand. More up-to-date technology, making more important decisions, and expanding more opportunities for collaboration.
The easy-to-series white LED products released this time are the latest ceramic-based light source products from Jingke Electronics. This series of products is based on APT patented technology - flip chip bonding technology, which realizes gold-free and solid-free plastic package of single-chip and multi-chip modules. It has high brightness, high luminous efficiency, high reliability, low thermal resistance and color consistency. Good and so on. The four new products of the Easy Series are:
Easy Star Series E-Star Series (1-3W). Yixing is the first product in the easy-to-series ceramic-based gold-free package. It is packaged on a small 3.5mm*3.5mm substrate and has a drive power of up to 3W and provides efficient, high-quality light output. To ensure good reliability, a high-quality white light source is provided for the majority of application customers.
Yihui series E-Light Series (5-10W). Yihui is the second product in the series of white LEDs. The product adopts the patented technology of flip-chip eutectic soldering to realize the gold-free package of multi-chip LED module, which has the advantages of high brightness, high reliability, low thermal resistance and good color consistency. Yihui packs 4 high-power chips on a small size substrate of 6.0mm*6.0mm, which can support 5-10W input power, providing a high grade and high quality for commercial, home, outdoor and automotive lighting. Quality light source.
Easy Flash Series E-Flash Series (for flash). Yixun is a white LED product designed for flash applications in the easy-to-series ceramic-based gold-free package. This product takes full advantage of the easy-to-use series of gold-free wires. It can be driven with a pulse current of 1000 mA or more, and instantly outputs high-intensity-density light pulses, and can realize ultra-thin, ultra-small size packaging, which will be a digital product for various application flashes. Intelligent transportation system provides an efficient and high quality product.
Yi Yao series E-Shine Series (10W or more). Yi Yao is a white light LED integrated light source product that can be customized according to customer requirements in the series of ceramic-based gold-free wire packaging products. This product adopts flip-chip eutectic soldering technology to realize gold-free wire encapsulation of multiple chips. A single light source can drive more than 10W, output luminous flux of more than 1000lm, and has high reliability, low thermal resistance and uniform light color. It is especially suitable for single-core luminaires, providing customers with a high-quality and easy-to-use light source.
It is worth mentioning that this new series of products has adopted the gold-free packaging technology for the first time. Therefore, the new crystal product release conference also provided participants with an opportunity to master the latest LED gold-free packaging technology. As is known, the traditional package structure mostly uses silver glue to fix the chip on the substrate, and the electrical connection must be made through the gold wire. Moreover, the silver gel contains epoxy resin, and the long-term environmental stability is poor, and the thermal resistance is high. The adhesive force is gradually deteriorated during the long-time lighting of the LED, which easily leads to shortening of the life of the LED. Because the gold wire is as thin as the hair, it is resistant to high current impact, and can only withstand a force of about 10g. Once it is subjected to thermal shock, it is easy to cause the gold wire to break due to the thermal mismatch of various packaging materials. Causes LED failure. The gold-free package is good for avoiding the above problems, ensuring high reliability, low thermal resistance and ultra-thin packaging.
The main reason why this easy series of new products made the industry a sensation is its technical advantages. In summary, there are the following points:
First, high reliability. It is well known that the LED module is packaged by using a plurality of positive-loading chips or vertical chips, and the gold wire is required to complete the electrical connection between the chip and the chip, the chip and the bracket, thereby increasing the risk of LED failure. The advantages of high reliability brought by the flip-chip gold-free package structure of the easy series are more obvious in the LED module of the multi-chip package.
Second, low thermal resistance can be used at high currents. In the traditional package, the sapphire layer is under the chip, so the thermal conductivity is poor, and the thermal resistance of the silver paste is also very high. In contrast, in the flip-chip gold-free package structure, the metal directly contacts the metal interface, so that the thermal conductivity is high and the thermal resistance is small.
Thirdly, the phosphor thin layer coating process is supported, so that the plane is coated with the phosphor and the light color is uniform. The traditional phosphor coating method has a non-uniform space and a large color temperature difference. The improved technology brings a more uniform spatial color temperature distribution.
Finally, no gold wire is obstructed, and ultra-thin packaging can be realized. Without the gold wire, phosphor coating is simpler and provides more room for lens design.
Nowadays, the massive use of LED has driven the rapid development of the LED industry in terms of quality. In the face of the global awareness of environmental protection and energy conservation, the development of LED lighting-related industries has become more and more important. Because of the huge demand for replacing energy-saving lighting in the world, the growth potential of LED light sources is full, and the universal popularity of LEDs is imperative. The Jingke Electronic Easy Series products not only dominate the future market demand for LEDs, but also lead the LED industry technology innovation trend, announcing that the LED lighting era has arrived.
