Why do workers wear anti-static clothing when wearing anti-static ankle straps?
The circuit of the integrated circuit component is reduced, the withstand voltage is reduced, and the circuit area is reduced, so that the electrostatic shock resistance of the device is weakened, and the electrostatic electric field and the electrostatic current become the deadly killers of these high-density components. At the same time, the widespread use of a large number of high-insulation materials such as plastic products has led to an increase in the chance of generating static electricity. Static electricity can be generated in daily life such as walking, air flow, and handling. It is generally believed that only CMOS-type wafers are sensitive to static electricity. In fact, highly integrated component circuits are sensitive. Therefore, wear an anti-static ankle strap and wear an anti-static suit.
In addition to wearing anti-static ankle straps, people must wear anti-static clothing to better control the static electricity of the human body. Because clothing can also carry a high degree of static electricity, especially most of the current clothing is chemical fiber, can produce thousands of volts of static electricity. Unprotected components are susceptible to electrostatic damage. And as the size of components decreases, so will the damage.
Therefore, most components are static-sensitive devices that require anti-static protection during manufacturing, transportation, and use.
