The huge mobile phone market demand is the main driving force for the development of LED flash. As manufacturers, LED companies are also targeting this emerging market and investing in the development of higher performance and more cost-effective flash products.
"Package-free" enters the LED flash market
With the continuous improvement of the quality of life, people's requirements for flash pixels are getting higher and higher, which is mainly reflected in two aspects: First, the brightness of the flash needs to be continuously improved; second, the light source is developing from a single single spectrum to a full spectrum with high color rendering. Various manufacturers are focusing their research and development efforts on improving the performance of LED flashlights from these two aspects.
It is understood that the current global LED flash shipments are basically supplied by two camps, namely OSRAM, CREE, and SAMSUNG that adopt vertical structures, and Philips Lumileds and Nichia that adopt flip-chip structures. Taiwanese manufacturers Epistar and New Century have also joined the flip-chip camp to attack the international LED flash market. Ou Weineng, product director of Jinko Electronics (Guangzhou) Co., Ltd., pointed out, "The biggest feature of mobile phone flash is that its instantaneous current is relatively large, using a large current of 1A to 1.5A. In this regard, flip-chip soldering technology is used to make a flash. Since gold wires are omitted, the electrical connection is made between gold and gold, which shows excellent reliability in withstanding large currents. At the same time, the phosphor is flat-coated to make the light emitted more uniformly."
Compared with the traditional packaging structure, the gold-wire-free packaging technology ensures high reliability of the product. It also has the advantages of low thermal resistance, ultra-thin packaging, small size and small color temperature difference. It can better leverage the advantages of LED. At the same time, it eliminates the steps of packaging and bonding. In theory, the cost of LED is reduced, which is conducive to the further popularization of LED products in the market.
According to observations, in the domestic market, LED flashlights are mainly vertical structures. As the only company in China that can mass-produce "gold-wire-free packaging" products and has been in mass production for three years, Jinko Electronics takes advantage of its flip-chip soldering technology and "package-free" R&D experience to boldly enter the LED flash market and launch the latest generation of gold-wire-free ceramic substrate packaged Flash LED light source - E-Flash LED. It has the advantages of compact structure, high luminous flux, high luminous efficiency, resistance to high current impact, and good heat conduction. Jinko Electronics has become the first and only domestic company to develop LED flash using gold wire-free packaging technology.
Innovation and accumulation are both fruitful and fruitful
Among many brand companies, what advantages does Jinko Electronics rely on to take the lead in package-free LED flash and become a benchmark?
Jinko Electronics, which adheres to the path of independent research and development and innovation, launched four products based on flip-chip soldering technology for gold-wire-free packaging in September 2011 - Easy series white light LEDs, becoming the first domestic company to apply flip-chip soldering technology to LED chips. After years of R&D and innovation, Jinko has become the only leading brand enterprise in China that has maturely applied flip-chip welding technology for high-power, high-brightness LED integrated chips. In 2013, it launched a "chip-level LED lighting overall solution", which can complete part of the traditional packaging process or save traditional packaging process links through new wafer-level processes in the LED chip manufacturing process, so that the final LED packaging volume can be reduced and the performance can be more stable.
Ou Weineng revealed that Jinko’s current monthly production capacity in high-power flip-chip soldering has reached 20KK. According to market demand, there will be a plan to expand production in three years and double it.
Jinko Electronics’ gold-wire-free flip-chip process has gained a certain reputation and popularity in the domestic market after years of technological accumulation and accumulation, especially for high-power products. As Jinko Electronics' flagship product this year, the flash-proof series of products using gold-wire-free flip-chip technology are foreseeable to cause a wave of enthusiasm in the industry with this precipitation.
With the development of global communication technology and the explosion of the mobile phone market, the demand for flash lamps will be increasing. In addition, in addition to being used in mobile phone flash lamps, the easy-to-flash series LED devices can also be used in traffic capture flash lamps and camera flash lamps. The fields of application will become more and more extensive. In this environment, I believe that the land of LED flash will become more fertile, and those who can cultivate the fruits of this land are often pioneers who are brave enough to innovate.
