Why test the effect of anti-static workbench?
The main difference between an anti-static workbench and an ordinary table is its remarkable anti-static effect. Some production workshops, such as aerospace working environment, SMT workshop, dust-free purification workshop, electronic equipment production and processing workshop, are equipped with anti-static products, and the anti-static workbench is one of the very important supporting facilities. So why test the effect of anti-static workbench?
Effect of detecting anti-static workbench 1: detecting surface impedance
Under different operating environments, the anti-static requirements for equipment and configuration are different, and the anti-static specifications are of course different for different types of work, so a set of standard anti-static equipment configuration is particularly important. To test the effect of an anti-static workbench, the surface impedance must first be tested, 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 mechanical equipment production workshops, The scientific laboratory has strict anti-static requirements for the anti-static workbench, so if you are not at ease with the performance of the anti-static workbench, you can simply prepare some equipment yourself to test the surface impedance.
In fact, there is a simple method for detecting the effect of surface impedance of the anti-static workbench, that is, take the four corners of the anti-static workbench and draw two cross lines, take four points on the center position, and place the electrostatic detection. The instrument detects and records the maximum value of impedance to ground at the four positions.
The second effect of testing anti-static workbench: Is the grounding standard?
Another effect of testing the anti-static workbench is whether it can ensure the correct grounding of the specification. This is related to whether it can achieve the anti-static effect. Many customers do not know the correct grounding method when they first buy it, so be sure to 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 an anti-static floor mat on the ground, and put all the workbench on the ground mat. The staff responsible for installing electrostatic sensitive devices must wear a special anti-static watch, etc. .
The installed anti-static workbench that meets the standard is not only convenient for testing the effect of the anti-static workbench, but also a good static safety workbench. Some drawings with static electricity and other plastic boxes, glass work objects, etc. are anti-static Factors or items related to the price of the workbench should not be stacked in a special anti-static file bag or in an anti-static drawer.
