Elimination and control of static electricity (ESD).
Therefore, it is necessary to establish an electrostatic protection system in the process of IC processing, production and packaging! IC packaging production lines have stricter requirements for static electricity. In order to ensure the normal operation of the production line, the overall decoration of its clean workshops with anti-static building materials, and the provision of anti-static clothing for all personnel entering and leaving the clean workshops, in addition to hardware measures, packaging companies can follow the relevant national standards and the actual situation of the company. Develop corporate standards or specific requirements in terms of anti-static to cooperate with the normal operation of IC packaging production lines.
Suggestions: 1). Assemblers need to wear anti-static clothing (such as anti-static clothes, hats, shoes, finger cots or gloves, etc.) and anti-static wrist straps (the wrist strap must be connected to the grounding system to quickly connect its surface or internal Anti-static pads must be used for the assembly table (workbench) and grounded; anti-static component boxes must be used for ICs; soldering irons, pin cutters, tin furnaces (or automatic reflow soldering equipment) must also be grounded . IC packaging bags and semi-finished products packaging materials should use anti-static sponge or packaging.
2) It is recommended to use suspended ion fan, ion wind nozzle, ion wind snake, ion wind gun and other special static elimination equipment in the production line. They use high-voltage ionization to neutralize the charge in the air with the static charge on the object, so as to achieve the purpose of eliminating static electricity, and has the characteristics of rapid and stable.
