Analysis: There is an urgent need for new capacitor technology standards | Focus on mid-to-high-end brand capacitor manufacturers

Lead-free electronic components With the continuous improvement of environmental protection awareness, people are paying more and more attention to the environmental pollution of lead and the damage to human health. In the past few years, the use of unleaded gasoline in automobiles and other transportation vehicles was a major move. Now, countries around the world are actively promoting the application of lead-free solder in the electronics manufacturing industry, which is a big step for mankind to become a green environmental friend. . In 2002, the European Parliament and the Council of the European Union passed regulations (WEEE/RoHS) on the 'Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment' and the 'Waste Electrical and Electronic Equipment Directive'. The Japanese government has also fully implemented the lead-free electronics manufacturing (JEIDA) since January 2003. The 'Administrative Measures on Pollution Prevention of the Ministry of Electronics and Information Industry' (Chinese version of WEEE) was promulgated at the end of 2003, and the final implementation date is January 1, 2005. It restricts six toxic and hazardous substances (one of which is lead) The use or prohibition date is July 1, 2006 (at the same time as the EU RoHS). This has played a positive role in promoting the formation of global unified laws and regulations, not only conducive to the development of China's electronic information product manufacturing, but also conducive to the design, production, testing and transportation of products in the entire industry worldwide. At that time, home appliances will determine the safe use period. Electronic companies are required to reduce or even eliminate the use of toxic and hazardous materials in the production process. The electronic information products in the national key supervision catalogue put on the market will not contain six types of harmful substances such as lead, mercury, cadmium, polybrominated biphenyl (PBB) or polybrominated biphenyl (PBDE). This requires related industries and companies to take early action to develop alternative environmentally friendly materials for these hazardous substances, or to minimize the use of these substances. It can be seen that strengthening the prevention and control of pollution by electronic information products and protecting the environment has become an unavoidable problem for countries all over the world in the new century. Developed countries have formulated environmental protection measures and created technical barriers to trade, and environmental protection laws have become two birds with one stone. In the two years since my country joined the WTO in November 2000, it has become an insurmountable and necessary process for industrial development to integrate with international standards in an all-round way. As far as our country is concerned, the social economy has entered a new stage, and attention to the living environment and sustainable economic development has been put on an important agenda. In the globalized production environment, 'lead-free manufacturing' is not only limited to technical discussions, but also extensively involves regional legislation, public opinion, market competition, and technological advancement needs that involve the public, government, research, enterprises, and the market. A public topic full of sociological meaning. It can be expected that lead-free technology will further mature, environmental protection legislation will become more and more stringent, corporate competition will become more intense, and lead-free manufacturing will be the core of the competition in the electronic assembly industry. The research and development of new materials and new processes will continue to expand and deepen. Lead-free electronics manufacturing is imminent. Recently, it has been reported that the EU will launch a regulation on e-waste in August this year-the 'Waste Electrical and Electronic Equipment Directive'. At that time, electronic products exported by Chinese home appliance companies to the EU will be levied an additional amount of garbage. Recovery costs. Among them, each export of a color TV or a mobile phone will be levied about 1-20 euros for garbage recycling, and some large electrical appliances will be even higher. Some analysts predict that this move will sharply reduce China's home appliance exports to Europe by 30%-50%. The ban on the use of six hazardous substances will take effect in July 2006, and there is still a certain buffer time. The EU currently accounts for about a quarter of China's home appliance export market and has become the main market for China's home appliance export. It is estimated that the export volume in 2004 will reach 150 million U.S. dollars, and the implementation of these two directives will force Chinese companies to use new environmentally friendly materials to replace some materials containing harmful substances when exporting to the EU, which will bring a lot of money to the companies. cost of. According to calculations, if the existing production raw materials are replaced with completely environmentally friendly materials, the production cost of the company will increase by at least 20%. It is expected that the implementation of these two directives will reduce exports by 30%-50%, and the market will be reduced by tens of millions of dollars. As the EU currently imposes quota restrictions on China’s color TV exports, domestic companies’ exports to the EU account for only a small share of only 400,000 units, and the quota of 400,000 units has not been completely used up by Chinese companies. In this sense, the promulgation of the directive in the short term will have little impact on the production, operation and export plans of most domestic color TV companies. At present, it is difficult for domestic enterprises to reach the environmental protection level of the European Union, Japan and other countries, and they are still at a loss in responding to these two EU laws.
