World electronic component technology development trend

First, coils, inductors

The coil and inductor market will be dominated by chip products, and the technology trend will be minimization, refinement and compounding. The chip products will be developed in both the winding and laminating directions. The trend for 1-A inductors is small package, low inductance and faster switching frequency. Advances in inductor technology for mobile phones have emerged in package thickness, for example, from 2mm two or three years ago to 1mm now. Significant improvements in this technology have allowed the miniaturization of ultra-thin component support devices to continue to attract the global electronics consumer market.

Second, the electronic transformer

The development of transformers will be centered on small, thin, lightweight and efficient. Pulse transformers in this area are moving in small size and surface mounting; the audio transformer market will decline.

In terms of product structure, the demand for toroidal core transformers will increase, and the demand for EI core transformers will decrease. At the same time, the demand for ferrite core transformers will increase, and the demand for laminated silicon steel transformers has dropped rapidly. The prospect of flyback transformers is still optimistic, and the demand for flyback transformers for HDTV, large screen, widescreen color TVs and computer monitors will steadily expand. The power transformers have a bright future, and computers and their peripherals and communication products have opened up a big market for them.

Third, micro motor

Micromotors will continue to evolve toward high torque, small size, high control accuracy, low power consumption, low noise, long life and low cost. At the same time, it is developing towards intelligence.

Micro-electro-mechanical machining technology will play an important role in the miniaturization of micro-motors. Matsushita Electric Industrial Co., Ltd. has developed ultra-small micro-motors with a rotor diameter of only 1 mm using semiconductor technology and thin-film process, with a rotational speed of 100-140 rpm. The drive frequency is 10kHz, which completely eliminates the machining and assembly process. Thin, intelligent and integrated technologies will be increasingly used in micro-motors, using new rare earth magnets, so that micro-motors can be made thin like flaps; motor and overall structure integration reduces size, simplifies structure, and improves System accuracy, reliability and servo system performance; micro-motors integrating electronic technology, micro-electronic technology and sensor technology can not only realize multi-function, but also improve motor control accuracy and sensitivity by means of computer memory, calculation and processing functions. Intelligent products.

Fourth, international leading companies

Although the technological progress of electronic components is far from being as rapid as communication, information and microelectronics technology, the development of electronic component technology has not stopped for a moment. Otherwise, the update of downstream complete equipment and technology will not be synchronized. Therefore, large manufacturers of electronic components have invested heavily in research and development, researching new technologies, new processes, new materials, new products, including patented technologies with independent intellectual property rights.

Some world-class electronic component manufacturers have annual research and development funding of at least hundreds of millions of dollars. As component manufacturers invest heavily in research and development, they maintain a leading position in technology and enjoy a large share of market share, and new products with independent intellectual property rights have guided the market direction. For example, the NXT patented technology developed by New Transducers Ltd. of the United Kingdom is not only used by British flat panel loudspeaker manufacturers, but most of the Asian flat panel loudspeaker manufacturers also use the company's NXT patented technology. Murata has a number of patented technologies in ceramic capacitors, including thin layer technology, metal forming technology, low temperature sintering technology, non-reducing material technology, etc., so that it can continuously introduce miniaturization, large capacity and high reliability to guide the world trend. Low-cost monolithic ceramic capacitors. The high-performance La-Co ferrite magnet developed by TDK has a residual inductance of 4500 gauss in the FB9 series and an intrinsic coercive force of 4.5 kOe. It is widely used in mandrel motors for office automation and audio/video equipment, and automotive starters. Motors and power control motors and various motors for household appliances.
