Electronic Components and IoT Sensors

Mr. Wen Xueli, Chairman and Secretary-General of China Electronic Component Industry Association, summarized the development of the electronic component industry. According to Wen Xueli, from January to September 2010, China’s total export volume of electronic component industries reached 38.801 billion U.S. dollars, an increase of 39.92% year-on-year. Among all major products, the export of inductive devices has the highest growth rate, reaching 58.75%. In addition, the export growth of electrical control components and capacitors also exceeds 50%.

For the development of sensitive components and sensors, Wen Xueli said that at present, China has developed a new generation of high-precision, sharp sensors have conditions, such as fiber optics, infrared, ultrasound, biological, intelligent and fuzzy control sensors, using MEMS technology micro- Sensors, etc. The main application areas of sensors in China are automotive, industrial process control, environmental protection, and transportation and energy industries. Home appliances, mobile communications, video and computers are expanding markets.

Wen Xueli stressed that "the world of things is connected, sensing is first." The most basic but at the core of the Internet of Things is the sensor. It is the largest and most basic link in the entire industry chain. However, Wen Xueli also pointed out that there are many problems in the sensor industry in China, which are mainly reflected in the small scale of enterprises and the lack of technological innovation.

Finally, Wen Xueli concluded that the development of the three major industries of the Internet of Things, solar photovoltaics, and LED industry has attracted the attention of enterprises and society, and the prospects for development are worth looking forward to.

New EMI/EMC Services

Murata (China) Investment Co., Ltd.'s senior product engineering teacher explains the development trend of electronic products in terms of the high performance of electronic products and the complexity and diversity of electronic interference noise environments, and focuses on the latest technologies and applications of Murata's EMI products. .

Fan Weijun pointed out that Murata used EMI filters to reduce noise in MIPI transmissions; a new common-mode choke coil was used to address radiated noise in high-speed mode while maintaining signal integrity in LP mode.

The common mode choke coil DLPONSC280HL2 developed by Murata for MIPI application can effectively suppress the signal distortion in the LP mode and improve the cell phone receiving sensitivity, which can be improved by up to 2dB. At the same time, Murata has proposed a USB3.0 noise suppression solution, targeting the 5Gbps transmission speed, selecting the common mode choke coils with matching impedance and transmission performance, and using ultra-small size 0201 large electric high frequency magnetic beads to solve the limited space problem. .

Murata's ceramic ESD devices offer low clamping voltage and insertion loss, and are resistant to repetitive shocks and are used instead of TVS.

A Power Transformer that is dedicated to supporting digital home appliances

Yamada Yoshiaki, head of the transformer division of Magnetic Products Division of TDK-EPC Corporation, pointed out that TDK is committed to developing a power transformer that supports digital home appliances.

Yamada summarized that TDK will develop ferrite core materials to miniaturization; improve the winding technology and wiring technology through the low loss of ferrite materials, and realize the thinning of resonant transformers; through the high saturation of ferrite materials The high magnetic flux density enables the thinning of the PFC inductor. The high saturation magnetic flux density of the ferrite material and the optimization of the core shape ensure the distance along the surface and realize the miniaturization of the flyback transformer.

Lithium Ion Capacitors and Applications

Sun Hao Yu (Shenzhen) Electronic Trading Co., Ltd. Sifang Hao Jie pointed out that the solar induced PAS capacitor, lithium ion capacitor has a high energy density.

Sifang Hao Jie said that the solar induced PAS capacitor has chemical stability, high capacity, all-polymer. Cylindrical PAS capacitors use a newly developed thin film electrode to achieve a low-ESR, small-size, 3.0V voltage. Lithium-ion capacitor uses activated carbon as a positive electrode, and uses a carbon material that can absorb lithium ions as a negative electrode to improve device safety.

Solar-induced capacitors function as a main power source or as an alternative battery. They are used as a backup power source for mobile phone time and calendar storage. They also serve as an auxiliary power source for LED flashes and high currents when the motor is started. Accelerating the progress of miniaturization and high-performance of passive components through the improvement of raw materials and packaging technology is the future direction of research on solar induced electricity.

High-end capacitors in new energy applications

Kimi Electronics FAEDirector Lai Xianneng was able to analyze the development trend and future use of advanced capacitor products such as tantalum capacitors, high polymer capacitors, high reliability ceramic multilayer capacitors, high voltage membrane capacitors, and Aluminum Electrolytic Capacitors.

Lai Xianneng focused on the development progress and products of small-sized high-capacity polymer polymer capacitors, high-bend-resistant ceramic multilayer capacitors, new-generation high-power film capacitors and high-temperature aluminum electrolytic capacitors for GE Motors. application.

High-density and high-speed connector solutions

Mitsuru Terabayashi, FCI's global consumer market manager, explained the high-density and high-speed solutions in the FFC&FPC connector.

Mitsuru Terabayashi stated that FCI sets the standard for connectors. In order to deal with the miniaturization of connectors, high-speed signal requirements and the development direction of electromagnetic interference shielding, FCI provides MID technology, TRI technology and BGA technology.

At the same time, FCI provided FFC, FPC, CIC several different types of cables and connectors to meet market demand. The cables provided by FCI enable cable locking and backflip drive and avoid misalignment. The excellent stamping process and plating process also highlight the advantages of FCI cables.

Lightning protection solution

Ye Shuming, the head of Penang Electronic FAE, has brought Penang Electronics' overvoltage protection solution to PCF 2010. Due to the widespread use of weak electrical equipment such as office automation and information networks in modern society, the widespread application of LSI large-scale integrated circuits and the operating voltage of IC circuits are getting lower and lower, and the ability to withstand surges is also getting lower and lower. Disasters are on the rise.

Ye Yuming stated that “only system integrators can become the answerer” and Penang Electronics proposes over-voltage protection solutions from application environment analysis, determination of test standards, protection circuit design, selection of components, system test verification, and field application optimization. . Penang Electronics' technology research and development covers raw materials, components, circuit design and testing.

Passive component tin plating market development

Rohm and Haas Electronic Materials Asia Limited Ding Huilong analyzed the industrial background of passive components, and discussed in depth the development trend of tin plating for passive components, and also illustrated the new tin plating process.

Ding Huilong emphasized that Rohm and Haas Electronics has focused on the concept of environmental protection in the development of new tin plating technology. In order to meet market demand, Rohm and Haas has introduced the product SOLDERONXP-100377 to increase the cost-effectiveness of tin plating.
