Midstream package on the real needs of the LED chip where?

As the source of the upstream chip LED field, the entire LED industry chain is the most talked about links. Insiders believe that the upper reaches of the development of large power companies to grow, you can let the LED industry 'all live', and even fundamentally change the pattern of China's LED industry. "

Therefore, how to meet the upstream upstream chip packaging product development direction, to meet the LED product system quality requirements and cost targets? Become the key to the whole industry chain and solve the problem of structural overcapacity. In this regard, the reporter interviewed the industry representatives of 30 LED packaging enterprise senior technical personnel, from their perspective to explore the true needs of packaging enterprises on the LED chip.

Quality stability is the primary consideration

In the actual use of the process stability and consistency is an important indicator to measure the level of LED technology, due to inconsistency of interference from a variety of manufacturing process is very easy to cause the different batches of the product quality, and consistency of LED chip products will undoubtedly affect the yield and stability of packaging products.

In the interview, each packaging enterprises have no exception, said that the primary consideration is the purchase of product quality and consistency of product quality.

Foshan City Star Au Optronics Co deputy general manager Li Cheng said that the main factors considered in the selection of the chip is certainly the performance, including the main optical parameters and reliability, and the photoelectric parameters to focus light efficiency, wavelength and brightness grading concentration etc.. Price war is fierce and stick to good quality, otherwise the company's products will not have a long life.

Guangzhou Hongli Au Optronics Co engineer Sha Lei pointed out that the chip is one of the most important factors that affect the stability of LED, the quality stability of chip is crucial to middle and downstream application package.

In addition, the voltage profile width and narrow will affect the LED of the light, relatively narrow voltage profile is more conducive to the concentration of LED when the concentration of Bin, improve the yield.

Taiwan Longda electronic Limited by Share Ltd said that the current development of the chip, the application is still the main backlight, so the packaging products, chip can provide the option is not much, because of the different power package collocation must choose different chips, in general, depends on the chip market, is in the same light effect the quality stability and price competitiveness two. Generally speaking, the quality stability is more important than the price.

Ashineon (Beijing) Technology Co., Ltd. executive vice president and chief scientist Liu Guoxu LED to the new century network reporter said, in the procurement of LED chip, with the stability of quality as the first element, the first to confirm the stability and reliability of chip technology.

Price is still the goal of the manufacturers wrestling

With the gradual opening of the LED civil market, many manufacturers have tried to find a way to break through the industrial upgrading in the amount and quality of. How to improve performance, reduce costs, has almost become the common goal of the entire LED industry chain wrestling.

The ETI devices division Wuhu ruituo electronic general manager Dr. Xu told reporters that at present, the main consideration is the price, for example, when the customer requests the whole light arrived at 100lm/W, we will consider to provide what kind of solutions to customers the most suitable, then in accordance with the demand for solutions to choose to have the advantages of chip to chip market now high efficiency, high brightness chip price is relatively high, the cost of packaging is definitely a pressure to provide appropriate and can meet customer demand is our package of brightness considerations.

Sichuan bonshine Industry Research Institute of Optoelectronic Technology Co Ltd President Mr. Ma Wenbo said, the first is the price paid more attention, because the chip accounted for a relatively large proportion of LED in the cost of the industrial chain, the decline in chip prices, can greatly reduce the price of the finished product LED. In addition, the current LED market competition, the cost advantage of the product is more competitive;

Guangzhou Hongli Au Optronics Co Engineer Sha Lei also mentioned that the light effect and the price is the primary factor, the market trend is now spelt lm/ yuan, the same price to buy a higher lumen will be more favored by the customers. Selection of chip products and existing chip products for comparison, the same price, choose the same high lumens lumens, choose low price of the chip, we hope that on the basis of the original, light efficiency and price advantage of the products.
