LED innovative packaging technology inventory

In recent years, with the popularization of LED lighting and the expansion of LED display application fields, the market has also put forward new requirements for LED packaging technology. so let's take a look at what gratifying achievements have taken place in the LED packaging field? The three-in-one in-line plug-in and the three-in-one in-line plug-in are the upgraded products of the current in-line plug-in products, which have not changed the dispensing process of the traditional in-line plug-in lamps, but have made breakthroughs in the product structure and combination, sealing RGB in one lamp. use four lamp legs. The traditional full color requires three single lamps as a phase element point, and now only one single lamp can achieve the same effect, thus greatly reducing the production and material costs. make the product have excellent price competitiveness. Outdoor in-line three-in-one solves the dilemma that users cannot have both display performance and weather resistance, and enables the industry to see the dawn of LED display packaging technology innovation. Piranha, Piranha LED, is a package, square, transparent resin package, four pins, a lack of feet at the negative pole LED. Piranha is a astigmatism LED with a luminous angle greater than 120 degrees, high luminous intensity, and can withstand greater power. Car brake lights turn signals are used more. It is said that this kind of LED immediately attracted everyone's attention when it was first born, and its development trend was as fierce as piranha. Another argument is that its shape is very similar to the piranha in the Amazon. The Piranha series display screen is a three-in-one in-line lamp between the traditional in-line lamp and the traditional indoor surface lamp. Compared with the traditional outdoor 246 and 346 in-line lamps, the Piranha series 5353 has the characteristics of high brightness, excellent white balance consistency, large viewing angle, synchronous light attenuation of red, green and blue Wick, gold wire welding and low failure rate, which are all the highlights of the piranha series. The outdoor protection grade of the full-color display screen completed by Piranha 5353 can reach over IP65. From the front/side, it eliminates the phenomenon of flower screen spots that have not been solved by 246, 346 and 546 lamp beads. In terms of heat dissipation, it is better than the lamp beads made of three-in-one surface stickers such as 3528 and 5050 commonly used outdoors. According to industry insiders, the market prospect of outdoor three-in-one in-line lamps is more impressive than traditional in-line lamps and surface stickers. Cob board chip (ChipOnBoard, COB) The process is first to use thermal conductive epoxy resin (Generally use silver-doped epoxy resin) Cover the placement point of the silicon wafer, then directly place the silicon wafer on the surface of the substrate, heat treat the silicon wafer until it is firmly fixed on the substrate, and then directly establish an electrical connection between the silicon wafer and the substrate by wire welding. If the bare chip is directly exposed to the air and is vulnerable to pollution or man-made damage, affecting or damaging the chip function, the chip and the bonding wire are encapsulated with glue. People also call this package form a soft package. Cog led packaging factory Hongqi has completed the integrated packaging technology that can use different substrates. At present, the initial use is double-chip sapphire substrate. Wang Binglong, chairman of Hongqi, pointed out that COG technology can lay LED grains on different substrate materials according to customer needs. The newly developed sapphire substrate integrated packaging technology can improve brightness by 30. This COG product seals LED on both sides of glass plate or sapphire plate, because the intermediate substrate is transparent in color and luster. the LED light will be more uniform, and this product omits the bracket process, which can reduce the cost of the bracket product and also has the advantage of simplifying the process.
