What role does antistatic clothing play in a wide range of electronics industries? Simply put, it is to prevent static electricity from collecting, reducing or reducing damage to electronic products.
Below we can explain the role of static electricity in the production of static electricity and anti-static work clothing fabrics and electrostatic damage to electronic products.
How is static electricity generated?
People's life and production are all related to static electricity, and static electricity directly or potentially brings various degrees of harm to human beings from various aspects. According to expert analysis, most of the fire accidents in workplaces such as gunpowder, chemical industry, medicine, and petroleum are caused by accidental discharge sparks due to static electricity generated by human activities exceeding safety limits.
Anti-static overalls fabric and principle
Anti-static overalls are uniforms that are sewn with antistatic fabrics to prevent static buildup on clothing. The antistatic fabric is a fabric obtained by mixing conductive fibers or antistatic synthetic fibers or a mixture of the two at substantially equal intervals or evenly during weaving. The conductive fiber is a general term for fibers made of a conductive material or a subconductive material using metal or organic materials in whole or in part, and has a volume resistivity ρv ∼ of between 104 ∼ 109 Ω/cm.
The harm of static electricity to electronic products
Electronic components vary according to their type, and the degree of damage by static electricity is also different. The lowest static voltage of 100V will also cause damage. In recent years, with the development of electronic components tending to be integrated, the corresponding electrostatic voltage is also required to be continuously reduced.
The electrostatic voltage induced by the human body is generally above 2-4KV, usually caused by slight movement of the human body or friction with the insulator. That is to say, if the electrostatic potential in our daily life is in contact with the IC, almost all ICs will be destroyed. This danger exists in any working environment where no electrostatic protection measures are taken. The damage of static electricity to IC is not only reflected in the manufacturing process of electronic components, but also in the process of assembly and transportation of ICs.
Practice has shown that anti-static overalls can effectively suppress static electricity and eliminate or reduce the electrostatic discharge hazard. When the human body performs various activities, the static voltage value on the clothing has greatly exceeded the electrostatic discharge damage threshold of many electrostatic sensitive devices, and the sensitive device may be damaged when touching or approaching these components. For the above reasons, in order to effectively prevent the electrostatic discharge hazard of the human body static electricity, the operator must wear anti-static overalls. This is also the role of wearing anti-static overalls. If you have different opinions on the role of anti-static overalls, you can connect us to discuss.
