After a round of debate on CSP marketization last year, the first half of this year, due to the transfer of CSP fluorescent film technology of a Japanese company, it has set off a new wave of attention.
Degao Huacheng signed a technical service agreement with Nitto Denko to undertake the localization development and service of the second generation of conformal packaging CSP fluorescent film technology (Conformal Coating CSP).
Just a few days before Deco Huacheng signed a technical service agreement with Nitto Denko, Zhongshan Stereo Optoelectronics announced a wholly-owned acquisition of the Nitto Dye fluorescent film project.
In fact, the CSP voice has been going on for a few years, but it has not been able to set off a big wave.
Tan Gang, vice president of sales of Donghao Optoelectronics, believes that “new products require new equipment, and CSP is born as a new packaging form. Due to the increasingly weak profit of the LED market, many companies are relatively cautious in investing in new equipment. , which affects the overall production increase.
Any new product needs some persistent people, and the persistent enterprise insists on working hard and insisting on paying. As the pioneer of CSP products, Dongxun Optoelectronics has been focusing on CSP products since 2015. In 2016, it has increased its investment in CSP products. In the development of CSP products, Dongxun Optoelectronics is willing to contribute Your own strength.
Based on the characteristics of CSP and some of the current products, CSP products are mainly used in the subdivision of special requirements such as backlight, flashlight, and automotive lighting.
In the general lighting market, compared with 2835, 3030, 5730 and other products, CSP can't compete in price. Therefore, many packaging manufacturers who do the general lighting market are only paying attention and have not made big moves.
"However, CSP products as the development direction of LED packaging, I believe that more and more companies will pay attention to this product. In fact, some companies with technological innovation ideas have been invested in large quantities." If so.
As the first batch of enterprises to deploy the CSP market, Dongxun Optoelectronics has now formed batch and scale production. It is understood that Dongxu Optoelectronics will carry out a new round of capacity planning in the second half of last year and will gradually release it in 2017.
Up to now, the CSP of Dongpu Optoelectronics above 1W has reached the capacity of 15-20KK/month. With the continuous availability of equipment, it is expected to reach 40-50KK/month capacity by the end of the year.
High-end market demand heavy volume CSP will continue to break out
As we all know, the application side has always had a misunderstanding of CSP performance and difficulty in use. After the market subsidence in the last two years, more and more customers are designing products for the characteristics of CSP, such as those already used in the lamp industry. The CSP product is the application end for CSP small size, high density illumination, high temperature resistance and high stability.
A series of CSP (1005, 1510, 1313, 1515, 1919, 2525, etc.) products launched by Dongsheng Optoelectronics have been recognized in the market. The overall application of the market is based on the "1515" and "1919" specifications. The product basically covers 1-5W power, and the price is more than 50% compared with 2016. It is in line with the current high-power market demand, so the cost-effective advantages of these two sizes are more obvious.
Tan Gang said frankly, "CSP products have already exploded in the car headlights, TV backlights, and mobile phone flashes. I believe that the follow-up will continue to break out in some general lighting (such as multi-color temperature dimming), special lighting and some consumer electronics. â€
As far as the application of the lamp is concerned, the CSP is mainly used in the two major markets of the original lamp and the rear lamp. The original car lamp market is more selected by Philips, Osram, Nichia and other brands, while domestic CSP package manufacturers choose to do the aftermarket.
Its requirements are mainly reflected in the following four aspects:
1. The adjustment of the illuminating light type and the improvement of the brightness to meet the requirements of the standard performance of the lamp;
2. The CSP product is modularized, which makes it easier for the rear-mounted lamp manufacturers to assemble and use;
3, the cost is reduced, so that the end user's use threshold is lower;
4, the stability of the product is more perfect, so that customers' confidence in use is stronger.
Modularization or will drive the general lighting market to break out
One of the biggest obstacles to the popularity of CSP in the past is the inconsistency of product specifications, and the rapid start-up of traditional SMD products such as 2835 is due to the standardization of specifications.
Liu Guoxu, executive vice president of Yimeixinguang, said: "There is currently no standard for the development of CSP. The size of everyone is not the same as that of medium power 2835, 4014, 5630. If a standard is formed, its promotion will accelerate. ."
In the second half of 2016, Samsung LED introduced CSP LED modules with color adjustability and increased compatibility modules. These modules will be mainly used in LED spotlights and downlights. The launch of the CSP module is Samsung's first introduction of CSP technology into the module product, thus playing more features of the CSP itself.
Since the LED module clearly defines the output lumens, color rendering index, system luminous efficiency, color temperature continuity and viewing angle width of different applications, it has greatly improved and effectively guaranteed the application quality of the LED lamps.
At the same time, modular products have brought more design space and rational use of limited R&D resources to downstream luminaire manufacturers.
"CSP (1515, 1919) as a standard package size product itself is designed to be easier for customers to assemble into modules according to their own needs. At this stage, more packaging companies use CSP as a module, the purpose is to Better serve customers and make it easier for customers to use CSP.†Tan Gang said that Donghao Optoelectronics will introduce third-generation CSP products to the market in the third quarter of this year.
Product categories of Cloth Pen Nib, it is belong to Passive Stylus Pen. Passive stylus pen is characterized by being cheap and without charging. But compared with the active capacitive stylus pen, its tip diameter is larger, so it cannot be used in works with high precision. Using high-quality conductive cloth head, smooth contact with the screen.
