In modern world, the environment issue is paid more and more attention. In such market situation, solar battery as one of future energy is placed much expectation. So far, Japan has been surpassing all the others in the production of solar battery. In future, the world output will continue increasing, especially when the European and American countries make greater plans in the production of solar battery. The technologies of screen printing will be extensively used and the demands will increase greatly especially in the production of silicon solar battery.

The proportion of body devices of each automobile is declining year by year; in contrast, that of electronic components is increasing gradually. It is reported that 70 million automobiles are manufactured in the world per year, and 20-30 thousand electronic components are placed on each automobiles. In future, with the development of high performance and environment friendly trend of automobiles, the electronic components on the body of automobile will be more and more. These electronic components, including HIC, MLCC, inductor and coil, are all the programs greatly requiring the technologies of screen printing, and the demands are inevitable to be enlarged.
