The value of the frictional voltage of anti-static ESD garments varies from fabric to fabric. The friction voltage of the conductive wire 0.5cm vertical strip anti-static ESD clothing is about 800V, and the grid friction voltage is about 500V. The friction voltage of the 0.25cm grid is between 200V. Therefore, when purchasing anti-static ESD clothing, clothing fabrics should be selected according to the * small limit of the electrostatic voltage value in the production workshop. Although it is difficult to remove static electricity, finding the right products and methods to remove static electricity is not a problem.
A person rubbing against a chair will produce a voltage of more than 1,800 volts, and when electricity is felt, the electrostatic voltage on a person is usually more than 2,000 volts, and when you see a discharge spark, the electrostatic voltage has exceeded 3,000 volts. When you read a plastic book, an electrostatic voltage of 7,000 volts is generated, and when you hear the "pop" of the discharge, the voltage has reached 7,000 to 8,000 volts. In life, such an impact is very small for us, but in actual production, a quiescent voltage of almost 20V is enough to destroy or reduce the performance of high-tech products such as chips.
In order to remove electrostatic voltage, some microelectronics factories and mechanical production workshops require employees to wear anti-static ESD clothing. Because anti-static overalls have a certain friction voltage value. It uses two principles, charge and discharge, and neutralization to prevent static electricity from accumulating.
The value of the friction voltage of the antistatic suit varies depending on the fabric. The friction voltage of the conductive wire 0.5cm vertical strip anti-static ESD clothing is about 800V, and the grid friction voltage is about 500V. The friction voltage of the 0.25cm grid is between 200V. Therefore, when purchasing anti-static ESD clothing, clothing fabrics should be selected according to the * small limit of the electrostatic voltage value in the production workshop. Although it is difficult to remove static electricity, finding the right products and methods to remove static electricity is not a problem.
