Analysis of the principle and function of PCB anti-static bag
Usually, the anti-static shielding bag adopts a two-layer composite or higher four-layer structure. The Faraday cage induction effect is formed in the bag, which protects the items in the bag from the electrostatic field to the greatest extent, prevents the accumulation of static electricity, and avoids the danger of static electricity.
PCB board anti-static bag material and function:
The PCB board anti-static bag adopts two-layer or four-layer composite material: (VMPET/CPE or PET/Al/NY/CPE). The PCB board anti-static bag has excellent anti-static, anti-radio frequency, waterproof vapor penetration and other functions, shielding ESD electrostatic discharge and external electromagnetic radiation from external personnel and equipment. It is suitable for the transportation and packaging of electrostatic sensitive high-tech electronic products such as PCB and IC.
The performance of PCB board anti-static bag:
The shielding bag has excellent anti-static, anti-radio frequency, waterproof vapor penetration, anti-salt spray and many other functions. Their unique four-layer structure creates an "inductive hood" effect to protect the contents of the bag from electrostatic fields. In addition, the inner layer is composed of vinyl that can eliminate static electricity, and the anti-static function is superior. The inner and outer layers of the anti-static shielding bag material are made of transparent anti-static materials, and the middle is a semi-transparent conductive metal layer, so it has good anti-static and electrostatic shielding properties.
The above is the analysis of the principle and function of the PCB board anti-static bag in the electronics industry. Hope it can give you some reference!
