Anti-static shoes have no clear life span
Anti-static shoes are a kind of esd work shoes worn by the production workshops and advanced laboratories of microelectronics industries such as electronic semiconductor devices, electronic computers, electronic communication devices and integrated circuits to reduce or eliminate static electricity. Protective shoes that can eliminate static electricity accumulation in the human body and prevent electric shock from power supply below 250V. Among them, the conductive shoes have good electrical conductivity, can eliminate the static electricity accumulation in the human body in a short time, and can only be used for the protective shoes without the danger of electric shock. Insulating shoes are protective shoes that can insulate people's feet from live objects and prevent electric shock.
In fact, depending on the actual situation, it is related to the actual environment in which the operator is wearing. Under normal circumstances, the anti-static index parameter is maintained for about 2 years. Because anti-static shoes are product safety protection products, it is necessary to regularly check the performance of anti-static shoes. During the wearing period of the shoes, the measurement is carried out according to GB4386-84 "Antistatic rubber sole shoes, conductive rubber soles resistance value measurement method". The resistance of the sole of the antistatic rubber sole must be in the range of 10^5 to 10^9.
Anti-static is a long-term key project of intelligent microelectronics factory. Due to the special nature of the electronics factory, in general, some departments in the electronics factory need to wear anti-static shoes and anti-static clothing, because the electronics factory works and Static electricity often occurs in production, and any mistakes or omissions in any link will lead to the failure of static electricity protection work. It even seriously affects the quality of the product.
