Anti-static system solution
With the rapid development of microelectronics technology, the harm caused by static electricity in its production and manufacturing process is becoming more and more obvious, and higher requirements are also put forward for the electrostatic protection technology itself.
Static protection and control is no longer just a problem of anti-static equipment, but a systematic work. It involves the manufacturing, assembly, processing, inspection, testing, maintenance, packaging, transportation, storage, and use of sensitive electronic products. It is also a series mode. Any mistake in any link will lead to the failure of the entire protection work. At the same time, it is directly related to the environment in which sensitive products are located (contact objects, air atmosphere, humidity, ground, workbench, chair, processing equipment, tools, etc.) and the operator's clothing (including clothing, hats, shoes, gloves, wristbands, etc.). Any omission or mistake will lead to the failure of electrostatic protection work. It needs to establish a complete protection system including design, operation, inspection, internal audit, training, etc. under strict standards and specifications. The work may involve various related departments. It can be said that the ESD protection level of a factory basically represents its control level of product quality. On the other hand, from a technical point of view, the quality problems caused by ESD protection are often hidden and potential, and it is difficult to detect and judge by conventional factory detection methods. The quality complaints caused by customers during the use of products, such as functional failure or instability, are often fatal. For these reasons, many companies, especially internationally renowned companies, regard ESD level as an important consideration for selecting partners.
At present, most of the ESD protection work of many domestic electronic product manufacturers is still at the superficial primary stage. The ESD protection work of the factory is nothing more than buying simple ESD supplies such as anti-static work clothes and wrist straps. There is no talk of establishing a systematic protection system. When many companies encounter on-site audits by major foreign customers, they are often rejected because of ESD problems after careful preparation. In fact, the reason is very simple: ESD protection is a continuous and systematic work, which cannot be solved by a few days of sudden response. Therefore, from the macro-trend of industry development, a systematic, standardized and normalized ESD protection system has become a top priority in the electronics industry, especially in the field of ESD protection.
The ESD protection system has different requirements for electronic companies of different sizes and levels. At present, electronic enterprises are generally divided into three categories: the first is enterprises with high-end requirements for electrostatic protection, such as manufacturers of chips and magnetic heads; the second is enterprises producing complete machines, electronic devices, and electronic finished products, such as IBM, Motorola, etc.; the third is enterprises that undertake OEM and ODM processing. They also have great differences in the scale level and cost investment in establishing a standardized ESD protection system.
Anti-static (ESD) system solutions are to provide consultants and experts for various electronic enterprises to establish a set of systematic, standardized, and standardized ESD protection systems. It is based on the internationally accepted normative guidance standards for establishing ESD protection systems (ESDA 20.20, IEC 61340-5-1, 61340-5-2), and refers to the national standards and industry standards of the People's Republic of China. It provides a full range of solutions for the establishment of the factory's ESD system, the establishment of EPA, the configuration of anti-static equipment, the packaging of sensitive devices, the processing of various links in production, personnel training and assessment, the establishment and inspection of internal audit systems, and testing methods. Moreover, it can conduct comprehensive diagnosis, consultation and evaluation of the established ESD protection system.
