The higher the risk of mobile phone battery capacity

The higher the risk of mobile phone battery capacity

Institute of Electronic Engineering, Beijing University of Posts and Director of Academic Committee Professor Song Junde of Artesyn Technologies today said the phone if the simple pursuit of manufacturing high-capacity, long standby time will be a security risk to mobile phone use because of the larger mobile phone battery capacity, the danger will be higher.

Have a website today reported that Changhong's new 365 long known as a rainbow powered mobile phone standby time has been extended to 300 days. The report came out, it immediately triggered the industry questioned.

Professor Song Junde said that the current handset market exists blind comparisons of the wind, while the standby time as an important indicator of comparisons: "You stand half of publicity, I claim that can stand a month, or even months."

He pointed out that the stand-by mobile phone batteries and mobile phone battery manufacturers is a very high technical threshold of the industry, on the cell phone battery materials and manufacturing industries have a very high demand, especially for high-capacity mobile phone battery, the "poor material and behind the industry made out of mobile phone batteries, like time bombs. "

But Professor Song Junde also said that by reducing standby power on and off mobile phones and base stations other than the wireless part of the link to the practice of standby time extension is feasible, but from the user perspective, how many people really need to up the number of standby time ten mobile phone?

An anonymous mobile phone manufacturers are also to Artesyn Technologies, says that most big mobile phone operators will not be long standby time for appeal, because the majority of consumers in terms of 3-7-day standby time is acceptable , "the pursuit of brand mobile phones newer technology is more and more intelligent operation and more energetic industrial design, this also for mobile phone operators to bring high profit return."

Domestic polysilicon plant to solve the solar cell industry

Domestic polysilicon plant to solve the solar cell industry

The world's largest producer of solar cells, starting in 2007, the annual provision of global supply of solar cells more than 1 / 3. Polysilicon enterprises in recent years because the domestic rise of polysilicon raw material supply to rely on imports was gradually changed by the self-sufficiency. Prior to 2007 the country only a few dozen tons of silicon material supply each year, mainly rely on imports of raw materials also; National polysilicon production in 2007 more than 1,000 tons, but consumption reached 8,000 tons of polysilicon; 2008 National 4,000 tons of polysilicon production, but consumption of polysilicon 12,000 t; 2009 National polysilicon plant at full production if the output is expected to reach 15,000 tons, has been able to solve the domestic demand for solar cell industry materials. <<

The production of pure polysilicon manufacturers are now not many, only two or three in particular, are large. For now, if you exclude the international financial crisis adversely affected the domestic market as a whole has polysilicon supply and demand balance, profitable.

Polysilicon prices mainly refers to the spot market price fluctuations, in fact, price volatility in recent years is not long-term agreement. We understand the situation from the current polysilicon spot prices sharply lower after after a long single price has been close to the basic control range. Market price of polysilicon has been the steady rise in June this year, is expected in the second half prices will slightly rise.

First half of 2009, Jiangsu to the third phase of the project three production lines of 5,000 tons of polysilicon production capacity gradually put into production and release. After 3 years of hard work, we have built the world's fourth ranked first in Asia polysilicon base. Stable production of the first half we on the one hand, one hand covering four main processes to implement the 50 technical improvements to reach full production capacity and further improve the quality and stability, enhance the process efficiency, reduce energy consumption, cost control projects. The end of 2009 production capacity is expected to reach 18,000 tons in 2010 to reach 21,000 tons, the production process will be best achieved through the technological transformation of existing production line equipment based on the increase. In the first half we achieved nearly 2,300 tons of polysilicon production, the current monthly production of over 1,000 tons, 8,000 tons of polysilicon production this year for the main supply of long single customer, a small amount of spot market supply.

Will keep any kind of industry competition, industry competition in terms of fact, from another dimension is also an opportunity. When a company fully prepared to do a deal with competition, with competition to seize the initiative chips, then the competition will play a business integration and restructuring, the role of conservation of existing resources. Therefore, in response to competition in Jiangsu to the major work done to improve core competitiveness, in terms of management and production techniques but also aspects of personnel training to do our best.

We believe that polysilicon production will finally definitely should not be "price war", but rather a "comprehensive war" absolutely do not blindly cut prices to win market best practices. Competitiveness of cost, service, quality and other aspects into consideration, only the lower prices at the expense of others, especially product quality, even a short time gain market advantage will not last. So the face of competition, we need to reduce costs, technological innovation, service, product quality and other aspects together, I believe we have a place in the global polysilicon market.

To polysilicon project from September 2007's first production line of 1500 tons since the quarterly production from the initial 160 tons to the current 2,000 tons, the cost is way down from the year 2008 the average production cost of $ 67 / kg to 2009 on June 36 dollars / kg. We understand that seven giant international polysilicon polysilicon production costs for the average 30-35 dollars / kg. As the new production lines into more than 3,000 tons of low cost, the cost to the level of polysilicon has been comparable to foreign counterparts.

Currently, the international part of the Siemens method other than by the improved production of solar silicon technology costs less than 20 U.S. dollars / kg. Siemens to further stabilize the existing production line improvement, mining capacity, the potential cost, while speeding up research and development outside the conventional Siemens technology improved, the scale of production is more low-cost, specialized in supplying solar cell using polysilicon polysilicon products to cope with international competition in the industry endeavors.

Jiangsu can plan for another three years of sustained investment to build world-class R & D base polysilicon production, in addition to providing raw materials for the photovoltaic industry, but also for the aviation, electronics and other high-tech industries to provide high-quality semiconductor material, lead the country to grow and develop optoelectronics industry, 5 years Xuzhou scale of the formation of hundreds of billions of new energy industries.

Solar mobile phone onto the market, thanks to solar cells and packaging technology integration

Solar mobile phone onto the market, thanks to solar cells and packaging technology integration

Following KDDI, Softbank Mobile after, NTT DoCoMo also shows that to be listed with the solar cell phone. These phones are Sharp and development of solar cell modules. Sharp LSI package with use of packaging technology and other fields, the solar battery module thickness reduced to approximately 800um, so that it is equipped on a mobile phone possible. It can be said for the installation of solar cell technology has opened up new areas.

Mobile phones equipped with solar battery module by 10 12.5mm x 18.75mm of solar modules. 10 units in series, each unit electrode surface wire bonding, the back electrodes connected to the printed adhesive Plaster on the floor. Among them, the low-bending, high-density wire bonding technology, thin modules contributed.

Module manufacturing process, solar cell manufacturing processes before the Division as the solar systems business. The same cell line and manufacturing process of household, about 15cm square formed on the wafer 96 (12 x 8) 12.5mm x 18.75mm cell pattern.

Then, the electronic components business of this Part re-use CSP (Chip Size Package) technology, the cutting unit on the floor and in the print settings, the implementation of wire bonding, and optical devices used in a transparent resin package. CSP technology in addition to its use of low curvature of wire bonding technology, the chip also includes the thin slab and thin package printing technology, the chip contains multiple pieces of one large floor molding technology. In addition, cutting and welding equipment used for manufacturing LSI can be directly used without special improvements.

During the problem is, a variety of materials caused by the thermal expansion coefficient between the module warpage. Compared with the LSI package, due to the larger, thus warping is relatively large. While Sharp did not disclose details, but you can clear that by optimizing the process and so on, to solve the warping problem.

In the future, Sharp ready for the relentless pursuit of smaller, thinner portable products, and further realize the thin solar cell modules. This may still need help installing the power of technology. This trend echoes with the installation of the firms have also given attention to the field of solar cells. Held in June 2009 solar event "PVJapan" on, NOK reference to display a transparent flexible substrate. Through the use of packaging technology, solar cell to achieve a new evolution.
