Why test the effect of anti-static workbench?
The main difference between the anti-static workbench and the ordinary table is its significant anti-static effect. Some production workshops, such as aerospace operation environment, SMT operation workshop, dust-free purification workshop, electronic equipment production and processing workshop, are equipped with anti-static products, and anti-static workbench is one of the very important supporting facilities. So why test the effect of anti-static workbench?
Detecting the effect of anti-static workbench 1: Detecting surface impedance
In different working environments, the anti-static requirements for equipment and configurations are different, and the anti-static specifications are of course different for different types of work. Therefore, a standard set of anti-static equipment configuration is particularly important. To test the effect of the anti-static workbench, we must first test its surface impedance, including the resistance of all exposed surfaces and painted surfaces. This is to check whether it meets the anti-static requirements of the industry's operating environment, such as high-end electronic machinery and equipment production workshops, Science laboratories have strict anti-static requirements for anti-static workbenches. Therefore, if you are not sure about the performance of anti-static workbenches, you can simply prepare some equipment to test the surface impedance.
In fact, there is an easy way to detect the effect of surface impedance of the anti-static workbench, that is to draw two cross lines at the four corners of the anti-static workbench, take four points at the center position, and place them on the electrostatic detector. The instrument is tested, and the maximum value of the impedance to ground at the four positions is recorded.
Detecting the effect of anti-static workbench 2: Is the grounding standard?
Another effect of testing the anti-static workbench is whether it can ensure that the standard is properly grounded, which is related to whether it can achieve the effect of anti-static. Many customers do not know the correct grounding method when they first buy it, so they must be Fully grasp the grounding work of the anti-static workbench. The grounding of the anti-static workbench is to lay the grounding wire in advance, put anti-static mats on the ground, and place all the worktables on the floor mats. The staff responsible for installing electrostatic sensitive devices must wear special anti-static watches, etc. .
The installed anti-static workbench that meets the standard is not only convenient to detect the effect of the anti-static workbench, but also a good electrostatic safety workbench. Some drawings with static electricity and other plastic boxes, glass work objects, etc. are related to anti-static. Factors or items related to the price of the workbench should not be stacked in a special anti-static file bag or an anti-static drawer.
