Recently, the lighting industry has made another major news. Zhongshan City Stereo Optoelectronics Technology Co., Ltd. (hereinafter referred to as Stereo Optoelectronics), which has been committed to promoting the development of domestic CSP, has wholly acquired the Nitto fluorescent film project in Japan.
Nitto Chinese name is Nitto Denko Co., Ltd., a listed company headquartered in Osaka, Japan, with 101 subsidiaries worldwide. It is reported that as early as 2012, Nitto cooperated with Jiangsu Changzhou Semiconductor Lighting Application Technology Research Institute to jointly research and develop CSP technology, and then Nitto assisted Sanan Optoelectronics, Hongli Zhihui, Stereo Optoelectronics and other enterprises to build a film-type The CSP production line provides the latter with an important raw material fluorescent film for the production of CSP.
Stereo Optoelectronics is also one of the early companies involved in CSP in China. It has cooperated with many companies such as Samsung, Dehao Runda, Jingyuan Optoelectronics and Xuyu Optoelectronics to cooperate with CSP projects.
After the completion of the acquisition, Stereo Optoelectronics will become the most complete CSP manufacturing enterprise in the domestic industrial chain. Not only will it master the core technology, but it will also significantly reduce the material cost of CSP, which will inevitably promote the rapid development of CSP.
Liu Zhihua, director of the market for crystal energy optoelectronics, believes that “acquisition of the Nitto fluorescent film project in Japan is also an important step in the development of stereo photoelectric strategy. Fluorescent film is one of the core technologies of CSP, which determines the control of color temperature and color tolerance.â€
In fact, the initial introduction of CSP solutions by LED companies was due to the need to save materials and reduce costs and improve product cost performance. So, what is the current CSP price/performance ratio?
As we all know, the CSP process is complex, the cost is very high, and the equipment investment is also very large, resulting in the CSP is currently in practical application, the cost performance is much lower than the formal and general SMD, whether it is single-sided or multi-faceted CSP. Therefore, if you can't make further breakthroughs in technology to reduce costs, CSP can't compete with formal wear and SMD in the field of general lighting.
According to Zheng Haibin, deputy general manager of Zhaochi Energy-saving Lighting Co., Ltd., “When you want to apply CSP in large quantities, you need to solve three major problems. First, improve cost performance and reduce costs. Customers are very sensitive to price; second, heat dissipation Space, design space processing; third, improve reliability, extend service life. As far as these three problems are concerned, for civilian lighting products, CSP is still somewhat tall."
Indeed, the current CSP is still in the promotion stage, and the cost is relatively high, but with the subsequent market upswing, there will be a large price cut. According to Liu Zhihua, the CSP products of Jingneng Optoelectronics have been developed for three years, and the technology has matured. The next step is to help more customers solve the problem of patching.
In the past two years, the CSP market was once cold. Many people in the industry believe that mainland manufacturers are basically in the small-volume production and marketing stage of CSP supply. No one has achieved mass production. This is actually thunder. The rain is small and self-proclaimed.
After entering 2016, driven by the chip packaging field and rising raw material prices, the midstream and upstream sectors showed signs of recovery, and various manufacturers became more active. Recently, manufacturers in the packaging field have been moving frequently, especially the CSP package, which is even more eye-catching.
Dr. Zhao Hanmin, CTO of Crystal Energy Optoelectronics, said, "We are very optimistic about CSP. 2017 will be the year of CSP explosion in the flash and backlight market. CSP has been widely used in TV backlighting."
In order to cope with the incremental demand of the CSP high-end market, Jingneng Optoelectronics actively expands production capacity and adjusts product prices to adapt to the market. In the first quarter of 2017, Jingneng Optoelectronics CSP's flashlights and lights customers demanded a large supply, and even the phenomenon of short supply.
Zheng Haibin also said, "Now our CSP has a certain amount of shipments. After a long period of time with our customers, we are constantly adding equipment. It is expected that there will be a big outbreak in the next quarter."
From the perspective of market application, CSP is more suitable for high-end market with high margins, and differentiated competition, such as mobile phone flash, automotive lighting, backlight display, special lighting and other fields have more advantages.
"At present, for the CSP market, everyone is still trying different ways and strategies to promote the layout in different markets." Liu Zhihua told Gaogong LED, Jingneng Optoelectronics began to import from the aftermarket, this customer comparison The optical and stability requirements are relatively high, and the price acceptance ability is relatively strong. Therefore, as soon as it is launched, it is well received by the market and is currently in short supply.
From this point of view, in the future, various package manufacturers in the CSP upgrade, mainly PK light efficiency, illumination and stability.
A through-bore slip ring is an electrical device that allows current to pass between two points in a rotating assembly without a physical connection. There is no break in the circuit. This is accomplished by passing the current through a rotating brush that contacts a stationary metal ring. The metal ring is mounted on the shaft of the assembly and provides a continuous path for the current.
It is an integrated circuit component that consists of two conducting rings that are separated by a gap or spacer. When the rings are brought into contact, current can flow between them and produce a rotational motion. Slip rings are used in various applications where high efficiency and low power consumption are essential, such as communication systems, motor control systems, and energy harvesting devices.
The through-bore design allows for rotation of the assembly while transmitting power or data. They are often used in applications where there is a need to rotate an object while keeping a power or data connection open, such as on a wind turbine or radar antenna.
The Oubaibo's through-bore slip ring is a newly designed product that has many advantages over other products on the market. It is small and lightweight, making it easy to install and use. The through-bore design also allows for a high degree of flexibility, making it ideal for use in difficult or tight spaces. Additionally, the Oubaibo through-bore slip ring is very efficient, providing a high degree of power transfer with minimal loss.
