HuaCan photoelectric jiang-bo wang, vice President: flip chip LED chip technology

On November 20th, sponsored by the OFweek China high-tech industry portal, OFweek semiconductor lighting network, OFweek lighting network to undertake 'the 11th OFweek LED to technology and market development peak BBS' star link was held at the ritz-carlton hotel in shenzhen. At the meeting, HC Semitek jiang-bo wang Corporation vice President and research and development department manager to share with you the 'flip the LED chip technology outlook' the theme of the speech. HC Semitek Corporation vice President and research and development department manager jiang-bo wang firstly introduces implementation of white light two kinds of schemes, this paper expounds the InGaN leds suitable for the reason of semiconductor lighting, and further explained the influence of high quality LED epitaxial materials, chip technology, packaging technology, phosphor and other technological factors. He also brought the white LED efficiency roadmap for everyone. When speaking of flip chip technology, jiang-bo wang deeply expounds the flip the advantages of the LED chip. And clearly points out that the current is the best solution. In recent years, in the field of chip, flip chip technology is emerging, especially in high power, the application of outdoor lighting is more popular in the market. Jiang-bo wang pointed out that the flip chip is popular in 2014, compared with the traditional dress of LED chips, flip the LED chip has a low thermal resistance, better light, no gold wire, etc. And these characteristics determine the flip chip LED chip in the backlight ultra high reliability requirements and lighting demand side displacement has obvious advantages. HuaCan photoelectric jiang-bo wang finally, jiang-bo wang also LED flip chip was introduced in detail a variety of packaging process, the flip chip scale packaging CSP. And further explained the flip chip 'high against P contact layer production, high against N contact layer production, the production of symmetric electrodes' three key technologies. , he points out, flip the LED chip and formal chip is compared, flip chip has a lower voltage, better droop.
