How to avoid electrostatic discharge
Component breakdown damage caused by electrostatic discharge is the most common and serious electrostatic hazard in the electronics industry. It is divided into hard breakdown and soft breakdown. Hard breakdown is a one-time breakdown of the component dielectric, burnt or permanent failure; soft breakdown is the performance degradation of the device or the parameter index is reduced. How to avoid it?
Antistatic loading boxes, component boxes, turnover boxes, turnover trays, etc. must be used for the transfer and storage of electrostatic sensitive components and printed circuit boards between processes. To prevent the accumulation of static electricity and cause harm. Electrostatic sensitive components and printed circuit boards must be used as anti-static shielding bags, packaging bags, packaging boxes, strips, baskets, etc. to avoid static damage during transportation.
In the production process of electronic products, the finished components and components are often in contact with and separated from equipment tools, and static electricity is generated. Antistatic seat cushions, turnover trolleys, maintenance kits, tools, work chairs (stools), etc. must be used. Static electricity is quickly vented by proper grounding.
Understand the electrostatic charging situation in the production process. The measurement of static electricity is mainly the measurement of electrostatic voltage, material resistance, grounding resistance, electrostatic shutdown period, electrostatic quantity, static elimination device static elimination performance, and cloth charge surface density.
Electrostatic protection work is a systematic project. Any omission or mistake in any link will lead to the failure of static electricity protection work. It must be prevented from time to time and everyone should be prevented.
