LED flash (FlashLED) seems to be becoming the scent of global smartphones. The eye-catching iPhone6, Meizu MX4, Xiaomi 4, vivoXshot, HTCM8, Huawei glory 6, and one plus mobile phones are all equipped with dual LED flashes. Under the megatrend, more and more mobile phones have added FlashLED flash applications to their designs. Thanks to the strong promotion of the huge mobile phone market, the LED flash market will undoubtedly provide a new opportunity for the development of domestic LED manufacturers. Leveraging the mobile phone market, high-brightness LED flash is imperative. FlashLED is mainly used in the high-powered fill light, flash, and imported into the smart phone design, playing the role of the camera module fill light. In the market of thin and high-quality camera phones, the use of higher brightness LED flash is the trend. In order to seize the LED flash market business opportunities, not only LED suppliers to introduce higher brightness, higher drive current products, LED driver IC manufacturers are racing to publish small-size, high-current and high conversion efficiency white LED driver IC solutions. Among them, ST's solution uses a thin fine-pitch ball grid array (TFBGA) package; ON Semiconductor uses a micro-quad flat no-pin package (QFN) 3.5 mm 3.5 mm 0.55 mm, 10 amp capacitor LED flash driver IC; National Semiconductor and Median have introduced a 23mm 23mm, 1.2Amp and 12-ball Wafer Level Chip Scale Package (WLSCP), 500mA LED Flash Driver, Developed in MicroSMD Package IC. At the same time, in order to achieve the purpose of adjusting brightness, each LED driver IC supplier built an internal integrated circuit (I2C) interface in the LED flash driver IC. In fact, LED flashlights have been in development for nearly a decade since 2005. Industry analysts pointed out that the FlashLED (flash) of mobile phones needs to be able to pass large currents instantaneously, and the technical threshold is high. It belongs to high-margin niche products. In the past years, the flash market has been monopolized by foreign brands (Philips, Osram, etc.). No one can cut in. The good news is that as the leader in the domestic flip-chip LED industry, Jingke Electronics is the first company in China to do mobile phone flash. As the technology-leading enterprise, the E-Flash Series of Jingke Electronics has been in the interest of people since its announcement. The media describes this in various angles. The product has been praised by the industry as the era of gold-free packaging. According to reports, E-FlashSeries is a white LED product designed for flash applications in ceramic-based gold-free package products. This series of products fully utilizes the technical advantages of flip-chip gold-free wire. It can be driven by pulse current of 1000mA or more. The instantaneous output brightness can reach more than 300lm, and it can realize ultra-thin, ultra-small size package, which will be the digital for various application flashes. Products, intelligent transportation systems provide an efficient, high quality product. The reason why the new products of Yixun series can cause a sensation in the industry is because of its unique and innovative technological advantages. In summary, the first benefit from the APT patented technology flip-chip welding technology, the single-chip and multi-chip modules of gold-free, no solid-state plastic packaging, to ensure high reliability, high brightness, high light efficiency Low thermal resistance, ultra-thin package, good dimensional and color consistency. Under the same LED area, Jingke's easy-flash series uses a flip-chip and gold-free package structure, and the large current flowing through the large current is 50-70 higher than the conventional package, which is an obvious advantage. . Based on this, customers have greatly improved the reliability and cost performance of the products. Therefore, Jinke's gold-free wire flash products are widely used in smart phones. Xiao Guowei, president of Jingke Electronics, said in an interview.
