Anti-static control treatment:
The main measures for static control are: leakage and dissipation of static electricity, neutralization of static electricity, shielding and grounding of static electricity, humidification, etc.
Component breakdown damage caused by electrostatic discharge is the most common and most serious electrostatic hazard in the electronics industry. It is divided into hard breakdown and soft breakdown. Hard breakdown is the one-time breakdown, burnout, or permanent failure of component media; soft breakdown is the performance degradation or parameter degradation of the device.
The transfer and storage of electrostatic sensitive components and printed circuit boards between processes in the production process must use antistatic loading boxes, component boxes, turnover boxes, turnover trays, etc. To prevent damage caused by static electricity accumulation. Static-sensitive components and printed circuit boards must be packaged as finished products with anti-static shielding bags, packaging bags, boxes, strips, baskets, etc. to avoid electrostatic damage during transportation.
In the production process of electronic products, the components and finished products often come into contact with and separate from equipment and tools. Friction generates static electricity. Antistatic cushions, revolving trolleys, repair kits, tools, work chairs (stools), etc. must be used. With proper grounding, the static electricity is quickly discharged.
Friction electrification and human body static electricity are the two major sources of hazards in the electronics and microelectronics industries, but the generation of static electricity is not the hazard. The hazard lies in the accumulation of static electricity and the resulting discharge of electrostatic charges, so it must be controlled. An electrostatic field creates an electrostatic field around it, which can produce mechanical effects, discharge effects, and electrostatic induction effects. Due to the mechanical effect of static electricity, the floating dust particles in the air will be adsorbed on electronic components such as silicon wafers, which will seriously affect the quality of electronic products. Therefore, antistatic measures must be taken to purify the working space. The walls, ceiling and floor of the clean room should be made of anti-static dust-free materials, and a series of electrostatic protection measures should also be taken for operators, workpieces and appliances.
