Anti-static (ESD) system solutions
With the rapid development of microelectronics technology, the damage caused by static electricity to its manufacturing process has become more and more obvious, and it also puts forward higher requirements for the static electricity protection technology itself.
Electrostatic protection and control is no longer just a problem of the provision of anti-static supplies, but a systematic work, which involves the manufacture, assembly, processing, inspection, testing, maintenance, packaging, transportation, storage, and use of sensitive electronic products. In addition, it is a series mode. Any error in any link will lead to the failure of the entire protection work. At the same time, it is in contact with the environment of the sensitive product (contact items, air atmosphere, humidity, ground, etc.). Workbenches, chairs, processing equipment, tools, etc.) are directly related to the clothing of the operators (including clothing, hats, shoe wipes, gloves, wrist straps, etc.). Any omission or error in any aspect will result in electrostatic protection work. It requires a complete protection system including design, operation, inspection, internal audit, training, etc., to be established under strict standards and regulations. The work may involve various related departments.
It can be said that the ESD protection level of a factory basically represents its level of control over product quality. On the other hand, from a technical point of view, the quality problems caused by ESD protection problems are often hidden and latent, and it is difficult to find and judge the routine inspection methods of the factory, and the functions caused by the customers in the process of using the product Quality complaints such as failure or instability are often fatal. For these reasons, many companies, especially internationally renowned companies, regard the ESD level as an important inspection content for selecting partners. At present, most of the ESD protection work of many electronic product manufacturers in China is still at the initial stage of surfaceization. The ESD protection work of the factory is nothing more than the purchase of simple ESD supplies such as anti-static work clothes and wrist straps. It cannot be said to be systematized. Many companies often make careful preparations when they encounter on-site audits by large foreign customers, but they are still rejected due to ESD issues. In fact, the reason is very simple: ESD protection is a continuous and systematic work, which cannot be solved by a few days of surprise. Therefore, from the perspective of industry development, a systematic, standardized, and standardized ESD protection system has become a top priority in the electronics industry, especially in the field of ESD protection. ESD protection systems have different requirements for electronic companies of different sizes and levels. The current electronic companies are roughly divided into three categories: one is companies that require high-end electrostatic protection, such as manufacturers of chips and magnetic heads; the second is manufacturers of complete machines, electronic devices, and electronic products, such as IBM, Motorola, etc.; the third is to undertake OEM, ODM processing enterprise. They are also very different in the scale and cost of establishing a standardized ESD protection system.
The anti-static (ESD) system solution is to establish a systematic, standardized and standardized ESD protection system for various electronic companies as consultants and experts. It is based on the internationally accepted normative guidelines for the establishment of ESD protection systems (ESDA 20.20, IEC 61340-5-1, 61340-5-2), and also refers to the national standards and industry standards of the People’s Republic of China for the ESD protection of factories. The establishment of the system, the establishment of the EPA, the configuration of anti-static equipment, the packaging of sensitive devices, the processing of various production links, the training and assessment of personnel, the establishment and inspection of the internal audit system, and the testing methods provide full solutions.
