Passive component situation is worrying Electromagnetic compatibility and circuit protection become the key

The China Electronics Association Information Center conducted surveys on the operating conditions of dozens of key companies in the electronic components industry from January to August. The results show that the profitability of the electronic components industry in China is still worrying. Wen Xueli pointed out that from the results of the survey, from January to August 2011, the sales revenue of key electronic component companies increased by 20.17% year-on-year. It is estimated that in the first three quarters of this year, the total sales revenue of the entire industry will exceed 1 trillion yuan. From January to August, the total profits of these enterprises increased by 2.29% year-on-year, reversing the decline in the previous two months, but considering that survey companies are mostly large-scale and well-run key enterprises in electronic components in China, Can not fully represent the situation of the entire industry, but in the survey companies, there are still nearly half of the backbone enterprises' profits decline.

In terms of component exports, he disclosed that from January to August this year, the total foreign exchange earned on exports of 14 major categories of electronic components in China totaled US$40.495 billion, an increase of 19.40% compared with the same period in 2010. This is the first time since the beginning of June of last year that China’s electronic components export growth rate has risen, and this increase has been entirely driven by magnetic materials because, with the exception of magnetic materials, the export growth rate of other products has fallen almost everywhere. From January to August this year, due to the continuous rise in rare earth prices, the total export of magnetic materials increased by 106.9% compared to the same period of last year.

Wen Xueli emphasized that due to the rise in raw material prices, increased labor costs, high taxes, power shortages, and financing difficulties in recent years, the production and operation of electronic components in China have become severe. Although the current import and export data of the electronic components industry is not enough to conclude that the electronic component industry's exports have entered a difficult position, but from the company's feedback, many companies have shown concern for future exports.

The global electronic components sales results survey for the past half year shows that as the domestic electronic components market becomes increasingly saturated, electronic components do foreign trade has become a trend in the industry, and plays a decisive role in the development of the electronic components market. According to statistics, from January to February of this year, the national electronic components industry achieved a sales value of 165.7 billion yuan, an increase of 35.9% year-on-year; the export delivery value was 105.9 billion yuan, a year-on-year increase of 28.8%, and 14.3 and 14 percentage points higher than the industry average. With regard to the output of electronic components, the industry produced a total of 13.79 billion integrated circuits, an increase of 34% year-on-year. The ever-increasing export volume of electronic components increasingly shows the signs that domestic electronic components market is becoming saturated and foreign markets are in short supply.

The "2011 China Electronics Manufacturers Procurement Behavior Survey Report" conducted by the China Electronics Show Organizing Committee and CNT Networks, etc. was recently released in Shenzhen. The survey shows that the procurement of Chinese electronics manufacturers is moving toward rationality. The Japanese earthquake at the beginning of the year tilted component purchases to Europe, the United States, South Korea, Taiwan, China, etc., and the Japanese brand's supply ratio fell sharply from 24.8% before the earthquake. 15.9%, Europe and the United States surpassed Japan to become the source of the largest supplier of components. The survey lasted for more than 2 months, and 1560 valid questionnaires were screened out. The survey participants were the decision-makers involved in the purchase of electronic whole machine manufacturers and design companies. The survey found that the new type of supply and demand partnership is moving from human-oriented to professional. At the same time, the proportion of suppliers who have participated in product design and cost analysis early has increased significantly from 49.7% in 2010 to 72%. The survey found that the average proportion of imported components purchased since 2011 was 58.6%, a slight increase from the same period in 2010. In addition to consumer electronics, manufacturers in emerging markets, such as industrial security, display lighting and automotive electronics, have become the main buyers of imported components.

The sales growth of electronic products as a whole improved slightly. In June 2011, the total consumption of electronic products in the United States was US$7.92 billion, a year-on-year decrease of 0.7%. In June 2011, the total consumption of home appliances, audio-visual equipment, and communication products in China was 54.2 billion yuan, an increase of 34.6% year-on-year, slightly faster than the increase in May. Taiwan’s electronic listed companies have announced July sales figures. In July, Taiwan’s electronics industry’s overall revenue decreased by 2.46 percent year-on-year. From the quarter-on-quarter growth rate, upstream -0.93%, 0.59% in the middle reaches, and -1.81% in the downstream, showing relatively weaker downstream conditions. In July, sales increased by more than 10% year-on-year, including mobile phone manufacturing, STN, optical lenses, EMS, NB, and mobile phone components. The areas that fell more than 10% mainly include DRAM manufacturing, IC design, IC manufacturing, LED and optical components, and passive components. , digital cameras, solar energy, monitors, consumer electronics, TFT.

In July 2011, Taiwan's electronic PCB manufacturing growth rate was -2.0% year-on-year, which was a 4.8% increase from the growth rate in June; the passive component year-on-year growth rate was -9.5%, which was a 2.6% increase from the growth rate in June. Compared with the sharply declining growth rate in June, the growth rate of the industry rebounded in July, but it was still lower than the level of the same period of last year and failed to show the signal of high season. TFT-LCD decreased by 16.8% year-on-year, which was a 1.8% drop from the June growth rate. STN-LCD faced downward pressure on prices, a year-on-year growth of 23.4%, and a 6.1% drop from June's deceleration. As the demand for downstream TVs has not improved, the prosperity of the panel industry has not improved. Solar energy fell 32.5% year-on-year, a decrease of 0.7% from June; LED and light components decreased by 15.1% year-on-year, a decrease of 1.5% from June. The solar market gradually bottomed out, but due to Europe entering the holiday season, it is expected that the economy will remain low. Due to the poor demand for backlight applications in the LED industry, the entire industry chain is facing price downward pressure.

Passive component plant reported "urgent single effect" in November

According to the performance of November, it is obvious that there is still a “temperature difference” in the rate of contribution of urgent orders. China Grand (2327-TW)’s consolidated revenue for November was 1.751 billion yuan, continuing to fall 4.2% from the previous month, which was the lowest monthly figure since the financial tsunami. However, Ruan Tengtang’s (3026-TW) urgency effect was more pronounced. November consolidated revenue was 1.242 billion yuan, with a monthly growth rate of 3.86%.

After the flood disaster in Thailand, due to the fact that products including electronic components and components were still not able to resume delivery quickly, the Taiwan Plant received orders from customers in November and most of them were presented as “urgent orders”, including passive components. It is also one of the group of beneficiaries of beneficiaries. In addition, due to the declining water level in the downstream stocks and the need to cover stocks, some passive components plants have recently emerged urgent orders. However, the passive component leader Guo Ju announced the combined revenue in November, still subject to customer adjustment inventory effect, the November consolidated revenue of 1.751 billion yuan, monthly reduction of 4.2%, the previous November consolidated revenue of 23.175 billion yuan, down from the same period last year 8.7%, although the performance in Greater China and North America slightly warmed up, but the overall revenue performance, or set a new low since the financial tsunami in September 2009.

From the end-user perspective, the demand for computer-related ethnic groups, industrial products and consumer electronics declined from the previous month, and the demand for EMS and dealership channels showed signs of a slight recovery. However, in order to make up for the fact, Taiwan’s parent company, including proxy active components, self-made passive components, and system modules, all experienced customers rushing through inventory to make up for the inventory, which led to the consolidation of revenue of 1.242 billion yuan in November. The rate was 3.86%. In the first 11 months of this year, the consolidated revenue was approximately NT$14.243 billion, an increase of 4.9% over the same period of last year.

With the development of intelligence, Vice President of the China Electronic Component Industry Association and Secretary General Wen Xueli said at PCF2011 that although the industry’s total profit decline has been reversed in the past few months, the profitability situation is still not optimistic. Electronic component companies must rely on the new generation. Opportunities brought about by the development of information technology and market changes, such as the innovation of intelligent terminals, smart homes, and internet of things, are undergoing a new round of transformation and upgrading. Secretary-General Wen Xueli mentioned hot markets such as smart homes and smart terminals, and leading international manufacturers such as Murata and Taiyo Yuden have once again taken the lead. At PCF2011, Murata Manufacturing Co., Ltd. and Sunjuk Electric Co., Ltd. respectively brought their own electronic component solutions in smart homes and smart terminals.

In smart home systems, home gateways, sensors, and communication modules are key components for intelligent control of home appliances. Murata can provide a full range of smart home solutions including network management, sensors, communication modules, and software. According to Jiang Yan, a senior engineer at Murata Manufacturing Co., Ltd., Murata has a wide variety of sensor technologies. After combining with the Murata communication module, a wireless sensor network can be built to realize remote control and status recognition of home appliances. The manager of the Sun Yutse Design Department, Jin Quanda, also brought forward solutions for smartphones. According to reports, Sun Yat-sen has successfully built a GaAs antenna switch substrate, and the product named “EOMIN®” overcomes the problems that it was impossible to install high-frequency circuits on GaAs antenna switches built into mobile devices such as smartphones and tablet computers. Has been applied in Japanese mobile phone companies.

Electromagnetic compatibility is a key fact. In the design process of electronic products, the link of electromagnetic compatibility and circuit protection is very critical and directly related to the availability of products. With more features being integrated into electronic products, and the speed of data transmission speeding up and miniaturization accelerating, more and more products are facing the challenges of electromagnetic compatibility and circuit protection. According to Zhu Wenli, deputy director of the Electronic Safety and Quality Inspection Center of the Ministry of Industry and Information Technology of the Ministry of Industry and Information Technology, when electromagnetic compatibility problems occur during the certification or testing of electromagnetic compatibility of electronic and electronic products, it is inevitable that this problem will be resolved from the common problems of electromagnetic interference, product composition and internal structure. , product testing of the substandard curve analysis of several aspects. After mastering some basic ideas, locating faults in electromagnetic compatibility problems will be relatively simple, and rectification will be completed more smoothly, thus accelerating the progress of product design and finalization or certification and listing.

In addition to design improvements, the improvement of the technology and performance of key electronic components is also key to solving electromagnetic compatibility issues. Professors from Harbin Institute of Technology Shenzhen Graduate School and Jun Ping said that for the increasingly stringent electromagnetic compatibility regulations and the continuous reduction in the volume of electrical and electronic products, new high-efficiency, small-size EMI suppression devices will gradually become a trend, integrating new types of filters and other devices. And other suppression devices face this vast development opportunity. Ray Bin, an electronic FAE manager at Penang, also stated that for a long time, passive components have been used in circuit design as a component of electronic products, and they have also been used in large numbers as protection components, including protection against electrostatic discharge.

With the ever-changing design of electronic products, more and more complex functions, smaller and lighter volume, more and more power saving, and increasingly high reliability, ESD protection design is becoming more and more critical. Importantly, this has also caused revolutionary changes to the characteristics of passive components. It must be adjusted to the specifications of passive components to have good electrostatic discharge protection for current electronic products.
