The Killer Of The Electronics Industry - Static Electricity
There are many ways to generate static electricity, such as contact, friction, rushing and so on.
The process can be summarized as: contact → charge → transfer → double electric layer formation → charge separation.
The static electricity on equipment or human body can reach up to tens of thousands or even hundreds of thousands of volts, and often hundreds to thousands of volts under normal operating conditions.
The human body can carry several thousand volts or even tens of thousands of volts of static electricity due to its own actions and contact with other objects-separation, friction or induction and other factors.
Static electricity is the result of an imbalance of positive and negative charges on a local scale.
It is a kind of electrical energy, which is retained in the performance of objects, and has the characteristics of high potential, low power, small current and short action time.
The breakdown damage of components caused by electrostatic discharge is the most common and serious electrostatic hazard in the electronics industry, and it is divided into hard breakdown and soft breakdown.
1. Hard breakdown is a one-time dielectric breakdown, burnout or permanent failure of components.
2. The soft breakdown is to cause the performance of the device to deteriorate or the parameter index to drop.
Friction electrification and human body static electricity are two major sources of hazard in the electronics and microelectronics industries. The hazard lies in the accumulation of static electricity and the resulting electrostatic charge discharge, so it must be controlled.
Due to the mechanical effect of static electricity, the floating dust particles in the air will be adsorbed on electronic components such as silicon chips, which will seriously affect the quality of electronic products. Therefore, anti-static measures must be taken to purify the working space.
The electrostatic protection work is a systematic project. Any omission or mistake in any link will lead to the failure of the electrostatic protection work. It must be guarded from time to time and everyone should guard against it.
If it is a product that manufactures electronic or wafer parts, it is recommended to use "Anti-Static Vacuum Pad" to avoid product damage or short circuit during the manufacturing or transportation process.
At present, CNL has cooperated with many large wafer or electronic parts manufacturers to use antistatic chucks, and has achieved great improvement.
