Abstract:It is said that, "science and technology is a double-edged sword". The improvement and revolution of technology promotes the development of society, but the environmental risks brought by new technology should be more focused by a comprehensive awareness, evaluation, prevention and control. Electronic pastes are a class of important materials manufactured for electronic components. In this paper, the new, underlying environmental problems brought by technological progress and development were analysized. Comparing from the preparation routes, course of using and subsequent damage as electronic waste to the environment, some new or greater environmental risks may appear due to the application of nano-metal conductive powders,the development of the base metals instead of precious metals and the trend of low temperature curing pastes. The risks are partly from objective technical factors, and also have the reasons of the subjective consciousness. However, the current laws and regulations have not been able to effectively control the risks. Therefore, it is important to strengthen the prevention and control of the environmental risks through production management and law when new technology is applied, only in that way, the coordinated development of social progress and environment-friendly could be realized.
