Surface resistivity test of anti-static table mat
At present, electronic companies in Japan, Europe and the United States have increasingly higher requirements for product protection and working environment. In order to reduce or eliminate the hazards of static electricity, it is necessary to lay anti-static table mats or conductive floor mats. After that, the working surface will discharge the static electricity of the human body, so that the ESD (anti-static) tweezers, tools, appliances, and meters in contact with the human body and the table surface reach a basically uniform potential, so that the electrostatic sensitive device (SSD) is not subject to electrostatic discharge such as friction, electrification, etc. The interference caused by the phenomenon, so as to achieve the effect of electrostatic protection. In turn, the working environment is improved, and the safety of enterprise production (fire) is strengthened.
The effective range of the anti-static mat is: the surface resistance (green layer resistance) is 106-109Ω, the anti-static layer, the back resistance (black resistance) is 103-105Ω, which is the conductive layer.
During the use of the anti-static table mat, you can use the surface resistance tester to place it on the surface of the anti-static radio station, and then press the use button of the surface resistance tester. Detect the surface resistance of the anti-static table mat. The test range is between 103-1012Ω, 103-105 is the conductive range, the green light shows, 106-1011Ω is the anti-static and antistatic range, the yellow light shows, 1012Ω is the insulation range, and the red light shows.
