The main form of electrostatic hazard in the electronics industry is the sudden failure and potential failure of components caused by electrostatic discharge, which in turn leads to a decline or failure of the performance of the whole machine. Therefore, the main purpose of electrostatic protection and control should be to control electrostatic discharge, that is, to prevent the occurrence of electrostatic discharge or to reduce the energy of electrostatic discharge to the damage threshold of all sensitive devices. In principle, electrostatic protection should be controlled from the generation of static electricity. Control the dissipation of static electricity. Controlling the generation of static electricity is mainly to control the choice of materials in the process and process. Controlling the dissipation of static electricity is mainly to quickly and safely discharge and neutralize the static electricity. The result of the combination of the two is It is possible to make the electrostatic level not exceed the safety limit and achieve the purpose of static electricity protection. The types and characteristics of several anti-static bags in the electronics industry are described below.
1) Shielded anti-static sealed bag
It is made of polyethylene and Germany imported antistatic agent, which is blown by special machinery. It is easy to pack and pinch with your fingers. Can reduce the complicated packaging procedures for you, can be used for packaging of electronic originals, PC boards, etc. The surface resistance value is 109-1011 Ω.
2) PE red anti-static bag
The anti-static bag is the best packaging material for the printed circuit board, so that the static electricity generated by the printed circuit board is reliably released to avoid damage. The technical indicators are as follows: MIL-B-81705B; internal and external surface resistance 103~≤1011Ω; electrostatic discharge time <2 seconds.
3) Anti-static shielding bag
In order to enable the plastic to shield electromagnetic waves, the plastic is treated with an antistatic agent for metallization, which has a good shielding effect. Surface resistance: 106Ω-109Ω
4) Anti-static bubble bag
Anti-static bubble bags and bubble sheets prevent product damage caused by collision or static electricity during production handling and transportation. This bag is suitable for the packaging of static-sensitive electronic products.
5) Anti-static moisture-proof bag
It is suitable for transportation and packaging of static sensitive high-tech electronic products such as PCB and IC. With anti-static, moisture-proof function. The inner and outer layers of the anti-static moisture-proof bag are made of transparent anti-static material, and the middle layer is aluminum foil with excellent barrier property and excellent conductivity, so it has good anti-static, moisture-proof and electromagnetic shielding performance, and the appearance is silver-white. Mainly used in the packaging of electronic products that are sensitive to static electricity and require moisture and electromagnetic interference.
