Професионално обяснение на опасностите от електростатичен разряд
Electrostatic discharge is very harmful to computer hardware. According to statistics, the damage rate caused by static electricity in the damage of semiconductor components is 59%. The breakdown damage of components caused by electrostatic breakdown is the most common and serious hazard in the electronics industry, especially in the manufacturing of electronic products. It is mainly divided into two Категории: Твърди срив и мек срив:
Трудно разбиване на електронните компоненти (известен също като незабавна повреда)
The so-called hard breakdown is a one-time permanent failure of the device, which makes the device completely lose its function and the device cannot be operated. This damage accounts for about 10% of the device's electrostatic damage rate (such as the output and input of the device are open or short-circuited). For hard breakdown, it can generally be discovered and repaired in time during our debugging, aging, and inspection Процес .
The characteristic of soft breakdown is that the device loses its function intermittently. The device can be operated but the performance is unstable or the parameters are reduced, which becomes a hidden danger. The harm it brings is more serious than hard breakdown. Because soft breakdown is difficult to detect in the early stage, the device is sometimes good and sometimes bad (due to the reduction of index parameters), and it is not easy to be discovered, which causes great trouble to the operation of the whole machine and fault finding. Although the performance parameters of the device have changed, it can still work normally and it is easy to pass the pre-factory inspection and flow into the hands of users. As time goes by during use, multiple soft breakdowns can cause hard breakdowns, causing abnormal operation of the equipment, which will Не само причинява загуби на потребителите, но неизбежно ще повлияе на добрата репутация на Inspur Products сред клиентите . Тази форма на щети на устройството представлява около 90% от електростатичните щети .
