According to the content, ESD standards can be roughly divided into three categories: guidance standards, product and method standards, and test standards. Among them, the guiding standard and its application guide are the core of the ESD standard. It specifies the structure and technical requirements of the ESD system and the means of realization, and is the key to the establishment of the ESD system. These guiding standards have also become the basis for the unification and certification of ESD standards. In fact, ESD S20.20, the core standard in the ESDA system, was compiled and formulated by the American Electrostatic Discharge Association at the request of the US military. One of its purposes is to form an audit and certification mechanism. Therefore, the form of the standard and the The content integrates the components of the quality management system. Just different from IS09001, ISO14000.OHSAS18001 and purely technical standards, ESD standard not only has technical requirements but also management requirements, it is a comprehensive system.

      Although the ESDS20.20 standard has been launched for more than five years, the certification mechanism has only been established for more than three years. It is still a brand-new certification system. Even so, it has received more and more attention and welcome. In 2003, there were only 9 certified companies. By November 2005, the number had reached more than 70, and the total number may exceed 150 this year. As far as the domestic situation is concerned, since 2003, a few companies have obtained the S20.20 certification, but these companies are all foreign-funded enterprises. There are mainly three types of certified companies: subsidiaries of well-known multinational companies, manufacturing companies in fields with high ESD requirements, such as chips, hard drives, communications and other industries, and EMS companies undertaking OEM and ODM business. Figure 1 is a statistical analysis made by Huanuo Fengyuan in November 2005:

From the pie chart analysis, it can be seen that the EMS industry has become the largest component of certified companies, which is exactly in line with the reasons and original intentions of ESD certification. In fact, it can be said that passing the certification is the best shortcut to establish a connection with the global ESD system.

      At present, in China, ESD S20.20 is not known to the majority of electronic product manufacturers, and the factories that can obtain the certificate through certification are basically very few foreign-funded enterprises. my country has become a processing base for electronic products, and many electronic product processing enterprises are concentrated in the Pearl River Delta and the Yangtze River Delta. At present, most of the ESD protection work of these companies is still in the initial stage of surfaceization. The ESD protection work of many factories is nothing more than the purchase of simple ESD supplies such as anti-static work clothes and wrist straps, and it is not enough to establish a systematic protection system. , There is a big gap from the ESD S20.20 standard, because it is not uncommon for ESD problems to be rejected by customers. The improvement of ESD technology level is the top priority of the entire electronics industry, and the promotion and popularization of ESD system standards is an arduous task. Fortunately, many people of insight in China have seen this and are making various efforts for this cause. Shenzhen Huanuo Fengyuan Technology Co., Ltd. has launched system establishment and certification counseling services in 2004, and DNV (Det Norske Veritas) and other certification agencies have also trained Chinese localized ESD system auditors, which greatly promotes this. business development.

concluding remarks

With the rapid development of electronic technology, people will have a deeper understanding of the role of ESD protection technology and protection systems. According to relevant ESD standards, the establishment of a complete ESD protection system will become the survival and The necessary conditions for development, which can greatly improve the quality and reliability of electronic products.
