The color of laser pointer has been determined.
To support the development of the capital of the field of electronic information materials from the following four specific areas: First, the study of advanced semiconductor silicon materials technology, the second is the high-end resist the industrialization of key technologies, development and industrialization of advanced interconnect materials, four development and industrialization of advanced packaging materials. Abstract: The electronic information materials and products supporting the modern communication, computer information network technology, micromechanical intelligent systems, industrial automation and home appliances and other modern high-tech industry. The scale of development and technical level of the electronic materials industry, has become an important symbol to measure a country's economic development, technological progress and national defense strength, an important strategic position in the national economy, technological innovation and international competition is most intense areas of materials. Two pieces of laser pointer are needed for this kind of laser pointer .
Electronic information materials including semiconductor materials, optoelectronic materials, sensor materials, magnetic materials, functional ceramics, optical transmission fiber, the green battery materials. Technology to predict the field of new materials the expert group meeting to discuss development trends and characteristics of electronic information materials, the status quo of China's development and with the world's major advanced countries, the gap in research and put forward China's development priorities in the field and key technologies. Electronic information materials trends. With the electronics and optoelectronics, photonics into microelectronic materials in the next 10 to 15 years is the most basic information materials, optoelectronic materials, photonic materials will become the fastest growing and most promising information materials. laser pointer is of the mini size. 
Therefore, in the laser cladding powder may be appropriate to reduce the carbon content of the powder, so can be required by the sealing surface hardness and strength, and reduces the formation of chromium carbide, relative to ensure the content of chromium. The role of convective mass transfer in the bath when the role of the laser beam can be fully stirred bath, bath gas mixture of things can go up to precipitate, forming a dense coating to ensure the melting quality. The plasma spray process is the use of plasma spray powder melting, acceleration, and then injected into the substrate material surface through the air space. This process is accompanied by air mixed with the solder layer, so often there are more pores and inclusions in the spray coating and interface parts of the distribution between the coarse dendrites, as shown in Figure 1c, d as shown.
