Market share is up to 20% in the year. Flip-chip Blu-ray chips will be the mainstream in the next few years.

Dehao Runda, who used to be in the early days of LED chips, but rushed to the evening, finally took the lead and decided to recapture the lost market share in the field of flip chip.

On the evening of April 14, Dehao Runda issued a notice stating that the company intends to issue non-public offerings of no more than 368 million shares at a price of not less than 5.43 yuan, raising funds of no more than 2 billion yuan. Among them, 1.5 billion yuan is intended for the LED flip chip project. After the project is completed, it will form an annual production capacity of 5 billion flip-chips. The other 500 million yuan will be used for LED chip-level packaging projects. It meets the company's annual output of 4.25 billion flip chip packages, and has an annual production capacity of 4.25 billion chip-scale packaged devices.

According to the calculation of Dehao Runda's “2016 Non-public Issuance Stock Plan”, after the completion of the flip chip project, the annual sales income will be 1.955 billion yuan and the total profit will be 423 million yuan. After the chip-level packaging project is completed, the annual sales will be realized. The income was 2.97 billion yuan and the total profit was 268 million yuan.

Dehao Runda said that the LED flip chip project and LED chip-level packaging project for this investment project are still in the gap period in China. The implementation of the fundraising project is conducive to the upgrading of LED chips and packaging industries, and further improve the company's industrial chain. structure.

According to the research of Gaogong LED, the flip chip products currently on the market are mainly provided by the new century, crystal power, and Guanghong in Taiwan, and foreign manufacturers such as Europe, Japan, South Korea and Japan also have small shipments. Domestic chip manufacturers, including Dehao Runda and Huacan Optoelectronics, have also gradually increased the mass production of flip-chips in the past two years.

According to financial report data, Dehao Runda LED flip chip was launched in 2014 and achieved small-scale mass production in 2015. In 2014, its flip chip sales were 799,100 yuan, and sales in the first three quarters of 2015 were 35,678,500. yuan.

In fact, Dehao Runda disclosed the issuance plan as early as 2015, and prepared to raise funds to force the LED to be flipped. Unfortunately, the adjustment of the additional price could not keep up with the decline of the stock price of Dehao Runda, and adjusted the price several times. After that, I finally stopped the issuance.

"For a long time in the future, flip-chip Blu-ray chips will be the mainstream." Dr. Mo Qingwei, vice president of Dehao Runda, believes that flip-chip Blu-ray chips are several years ahead of CSP development. At present, flip-chip Blu-ray chip technology has gradually matured, and many companies have also launched products.

From the current three process routes of chip-level packaging, the key prerequisite for the realization of chip-level packaging is the development of flip-chip, which is the purpose of Dehao Runda is willing to invest 1.5 billion yuan for flip chip.

Although LED chips are still the main packaging market for most of the general-purpose lighting market, flip-chips will have more and more advantages in special applications due to their unique high reliability, such as automotive lighting, ultra-high power lighting and other market segments. .

With the slowdown in demand growth in downstream lighting applications and the large-scale expansion of upstream epitaxial chip companies in the past two years, the competition for domestic LED chips and packaged devices has entered a stage of white-hot. In the field of chips, flip-chip technology is emerging, especially in the high-power, outdoor lighting applications market.

As we all know, flip chip efficiency is higher, the drive current range is wide, and the high current impact resistance is excellent, which is about twice the rated current of the existing dress chip. At the same time, as flip-chip LEDs are gradually gaining attention from the lighting market, more and more LED manufacturers are beginning to invest in R&D and production in this field in an effort to accelerate the development of flip-chip technology in lighting applications in terms of technology and cost.

LED flip chip combines the advantages of pre-loaded chips and vertical chips, and has broad application prospects in general lighting, automotive, high-power lighting, large-size backlights, projectors, flashlights and other fields.

With the continuous investment of several major chip factories in the field of flip chip, the spring of flip chip has arrived.

The domestic chip maker Huacan Optoelectronics has accumulated many years of experience in flip-chip research and development, and has comprehensively proposed the flip-chip "Yao" series--white-light flip-chip LED chip. On the one hand, through technology optimization, it has made further breakthroughs in light efficiency, in package reliability. The protection aspect is constantly improving, on the other hand, chip-level fluorescent coating is realized, which is convenient for direct COB application.

It is understood that Huacan Optoelectronics has realized the industrialization of high-power flip-chip LED chips. The medium-power flip-chip has a main wavelength of 455±5 nm and a driving current of 180mA. The blue light power is ≥320mW, and the power conversion efficiency is ≥60%. Under Tc=5000K, Ra>80,180mA driving current, medium power chip scale package white LED light effect ≥155lm/W, light source module light efficiency>140lm/W;

Because flip chip heat dissipation, high reliability, and high current drive, it has a high cost performance, so "flip chip + chip scale package" has become the perfect combination, in terms of LED white light device cost and reliability Has a strong advantage, has become the mainstream direction of the development of the LED industry in the past two years.

From the current market trend, Japan, South Korea, Europe, the United States, Taiwan and other companies have successively launched flip-chip LED chips and chip-scale package products, further demonstrating the future development potential and outstanding technology of chip-level package products realized by flip chip. Advantage. As the LED lighting market gradually matures and other various application markets come, there will be a large market space for chip-scale packaged LED products in the future.

"Flip-chip technology has been relatively mature, and light efficiency has continued to increase. It has entered the initial stage. The proportion of flip-chip LED shipments can be increased to 32% in 2019." Bian Defei, vice president of Huacan Optoelectronics, said that flip chip Can be widely used in general lighting, special photos, high power, flash, projection, medium and large size backlight and other market segments.

When it comes to the advantages of flip chip, Bian Defei believes that flip chip LED chips have lower chip thermal resistance (over current use), better chip light extraction (high efficiency), and no gold wire (integrated, high density).

"Currently, Huacan Optoelectronics flip-chip production capacity is 20,000 pieces / month (2 inches), and in 2016 it can reach 100,000 pieces / month (2 inches)." Bian Defei said that Huacan Optoelectronics is based on customized Demand, together with customers to develop the flip chip market.

According to statistics from the Institute of Advanced Industrial Research and Development LED Research, according to the current production capacity of 500,000 pieces/month of Huacan Optoelectronics, the production capacity of Huacan Optoelectronics flip chip will account for more than 20% during the year.

As the market share of flip chip is getting higher and higher, more and more companies investing in LED flip chip in China, and technology is becoming more and more mature, which will accelerate the development of CSP.

"CSP, as a new packaging technology, attracts industry attention in the next generation of discrete high-power LED applications, and has a large room for improvement in lm/$. With the improvement of flip chip yield and capacity scale Expanding, its price advantage will be more reflected. Today, CSP has not only stayed in the R&D room, but has already produced in large quantities in some applications, and showed its advantages and value.” Dr. Liu Guoxu, Executive Vice President of Yimeixinguang, said.

"Since this year, the need for manufacturers to reduce costs has become imminent, so the role of CSPLED in the LED industry is becoming more and more important. It can be said that it has become the wisdom of the majority of LED manufacturers to reduce manufacturing costs, very small But it has the same luminous flux, and the chip requires less raw materials.” Zhou Xuejun, marketing director of Lumileds Asia, revealed that the current CSP LED can reduce the cost by nearly 40% compared with traditional LED.

LED wash wall lamp, as the name implies, let the light like water wash the wall, mainly used for building decoration lighting, and also used to outline the large buildings.Since LED has the characteristics of energy saving, high luminous efficiency, rich color and long life, the washing wall lamp of other light sources is gradually replaced by LED washing wall lamp in 2013.
