Around the LED packaging technology innovation

In recent years with the expansion of the popularity of LED lighting and LED display applications , the market for LED packaging technology have made ​​new dends , so let's look at the field of LED package which appeared gratifying accomplishments ?Triple lineTriple line is the line product upgrades , did not change the traditional light -line packaging process , but in the product structure and composition of the breakthrough, the RGB sealed in a lamp , the lamp uses four feet . "The traditional full-color lights to three single- phase as a prime spot , now just a single lamp can do the same effect , thus greatly reducing the cost of production and materials to make products with excellent price competitiveness ." Outdoor display inline triple solve the user can not have both the performance and durability of the dilemma , let the industry see the LED display packaging technology innovations dawn.PiranhaPiranha LED, a package, a square , a transparent resin package , four -pin , there is a lack of the negative electrode at the foot LED. Piranha astigmatism type of the LED, the light emitting angle greater than 120 degrees, the luminous intensity is high , and can withstand a greater power . Vehicle brake lights \ steering lamp more. It is said that this LED just born immediately attracted everyone's attention , and its development trend as ferocious piranha like it was this name . Another argument is that because of its shape like a piranha in the Amazon .Piranha series display is a line between conventional and traditional interior lamp table lamp lights affixed between the triple line , as opposed to traditional outdoor lamp made ​​of 246,346 -line screen , piranhas series 5353 high brightness , white balance, excellent uniformity , viewing angle, red, green and blue light fades wick synchronization , gold wire , low failure rate characteristics, these are the biggest bright spot piranha series . Piranha 5353 by a full-color screen to complete outdoor protection class up to IP65 above , from positive / side, eliminating 246,346,546 lamp beads has not been possible to resolve the " Huaping spots " and so on. The heat better than commonly 3528,5050 and other outdoor triple paste made ​​of lamp beads . According to insiders claimed that the market outlook for outdoor triple line than traditional lamps and table lamps line even more impressive stickers.cobCOB (Chip On Board, COB) process is first placed on the substrate wafer surface is covered with a thermally conductive epoxy point (generally an epoxy resin mixed with silver particles ) , and then placed directly on the surface of the substrate wafer , the heat treatment firmly fixed to the silicon substrate and subsequently a wire bonding method and then between the silicon wafer and the substrate to establish a direct electrical connection .If the bare chip is directly exposed to the air , vulnerable to contamination or human damage , affect or damage the chip function , so they glue the chip and bonding wires encapsulated . People also call this package in the form of soft encapsulation .COGLED packaging factory HARVATEK different substrates can be used to complete the integrated packaging technology is currently used in the initial double throw pieces of sapphire substrates. Wang Qi , chairman Wang Binglong noted COG technology in accordance with customer demand , the LED die to play on a different substrate materials. The newly developed integrated sapphire substrate packaging technology can enhance the brightness by 30% , this product will be LED COG sealed in glass or sapphire plates on both sides , because the intermediate substrate transparent color , LED light will be more uniform, and this product bracket process is omitted, the stent can reduce costs, simplify processes have advantages .
