With the progress of science and technology, the continuous development of information technology, nano electronic technology has been widely used, and it has been extended to all fields of society, it not only represents the trend of the development of microelectronics, more conducive to the development of new technology.As a traditional microelectronics and printing of cross electronics, is now at the beginning of industrialized mass production, printing electronics through the printing method of functional change, the future will produce many cheap super light thin super soft electronic products.In the traditional printing, screen printing has a great potential on the mass production of organic electronic devices, in recent years, screen printing has developed into a modern industrial technology, is widely used in electronic industry.Ago, is widely used for printing the traditional screen printing circuit board, now has developed into all walks of life to production without a way of printing.Screen printing used in the manufacture of electronics, such as biological sensors, transparent conductive film and solar cells.

         Electronic technology integrating traditional printing technology, printing and traditional printing technology is applied to electronic manufacturing, the technology covers the organic electronics, flexible electronics and plastic electronics, and other new technologies.Printed electronics and manufacturing process have a common characteristics of traditional printing, can realize the mass production of large area, especially the volume of the manufacture of continuous production.

        Compared with traditional silicon-based microelectronics technology, the traditional electronic manufacturing is a process of reduction of material manufacturing, and printed electronics is increasing material manufacturing process.By printing equipment investment is extremely low, is used for electronic devices and has nothing to do with the basal material, printing processing of electronics can be in various substrate preparation of electronic devices, including all kinds of flexible base materials.In terms of performance printed electronics while not silicon-based microelectronics, but the printing electronic device has the characteristics of large area, flexibility and low cost, is what silicon-based microelectronics does not have.In general, they are not replaced by each other, but complement each other, each have each market position, and printing of electronic technology market is a rapid development and huge market potential.

        Industry since 2009, China began to focus on electronics, printing, by contrast, the domestic printing electronic technology research and development and industrialization of relatively backward and abroad.Although more than domestic industries have begun to print the advantages of the application to the part of the production process, such as surface electrode preparation for production of crystalline silicon photovoltaic (pv).Now in order to realize "green of printing, functionalization, three-dimensional, device", to be without printing the application of electronic technology.Electronic devices in the future to develop in the direction of light, soft, thin, in the process of printing electronic will appear more and more advantage.
