Features of electrostatic protection for electronic products
The electrostatic protection of electronic products has the following obvious characteristics:
1. The ultra-fine and ultra-thin processing technology and the fine structure of the product make it significantly more sensitive to electrostatic discharge than other industries and products. Even the electrostatic discharge voltage below 20V may cause damage or destruction of electronic components.
2. Products that are sensitive to static electricity, such as semiconductor discrete devices, integrated circuits, thick film circuits and resistors, capacitors, piezoelectric crystals, etc., especially the first three types of electronic sensitive devices, can be described as the "heart" of electronic equipment. In view of this, the problem of protection against electrostatic hazards involves almost all technical fields of electronic products, especially those electronic devices that require small size, high operating frequency, and high mounting density.
3. Electrostatic protection is a systematic project, which involves the manufacturing, assembly, processing, inspection, testing, maintenance, packaging, transportation, storage, and use of sensitive electronic products, and it is a series mode. Mistakes will lead to the failure of the entire protection work; at the same time, it will be in contact with the environment of the sensitive product (contact items, air atmosphere, humidity, ground, workbench, chair, processing equipment, tools, etc.) and the clothing of the operator ( Including the clothes worn, hats, shoe wipes, gloves, wrist straps, etc.) are directly related. Any omission or error in any aspect will result in the failure of electrostatic protection.
In view of the above-mentioned characteristics of the electrostatic protection of electronic products, it is best to formulate a series of standards that are compatible with it. A better choice is to adopt a comprehensive standardization method, focusing on the system requirements of electrostatic protection, and considering the formulation and coordination of related standards. Only in this way can all aspects of anti-static work in all aspects be integrated into the standard specification. An orderly state.
