What's the point of wearing anti-static clothing?
"Static electricity" has been taken seriously by more and more companies. According to relevant data, Japanese statistics: 45% of unqualified devices are caused by electrostatic discharge damage. TI company statistics: among customer failed devices, failures caused by ESD account for 47%, etc. etc. Therefore, wearing anti-static clothing has become a standard feature on many production lines. However, wearers often complain about discomfort and trouble, but this is not negotiable. In order to protect the product from harm, anti-static clothing must be worn. Let's introduce the significance of wearing anti-static clothing.
First, we must understand the characteristics of electrostatic damage:
1. Concealedness: The human body cannot directly sense static electricity unless an electrostatic discharge occurs. However, if an electrostatic discharge occurs, the human body may not necessarily feel an electric shock. This is because the electrostatic discharge voltage perceived by the human body is 2-3KV.
2. Latent performance of some electronic components does not significantly decrease after being damaged by static electricity. However, multiple cumulative discharges can cause internal damage to the device and cause hidden dangers, and increase the sensitivity of the device to static electricity. There is no cure for the problems that have arisen.
3. The harm of static electricity is always present, and it often occurs at a certain point in time where you are not paying attention.
4. Complex electrostatic discharge damage deboarding work is time-consuming, labor-intensive, and expensive due to the delicate and tiny structural characteristics of electronic products. More complex technologies often require the use of precision instruments such as scanning electron microscopes. Even so, some electrostatic damage phenomena are not It is difficult to distinguish it from damage caused by other reasons, causing people to mistakenly regard electrostatic damage failure as other failures. This is because before electrostatic discharge damage is fully understood, it is often attributed to early failure or failure of unknown circumstances, thus unconsciously covering up the failure. The real cause of the failure.
5. On the surface, the serious ESD problem only affects users of finished products, but in fact it also affects manufacturers at all levels.
6. Static electricity will not be eliminated completely. We can only take corresponding electrostatic protection measures based on the anti-static threshold of the product.
After the above introduction, it is not difficult to understand the significance of wearing anti-static clothing. If you do not wear anti-static clothing, static electricity will be transmitted to components through human hands. Those components whose carrier movement is characterized by electrical connectivity will be interfered by static electricity. , the arrangement of internal carriers may change, which will directly affect the quality of the product, and even cause the product's performance to degrade or even lose its function. In addition, it can also cause harm to the human body, so we must attach great importance to it. In special working environments, we must pay attention to personal safety and not harm ourselves. Therefore, we must wear anti-static clothing or related anti-static products.
