What is a qualified anti-static workbench
Do you still compare prices and worry about suppliers’ inconsistent quotations? Do you know that the anti-static workbench you bought is truly anti-static? I don’t know how to answer many questions. Let’s take a look at the following explanations, which may improve your ability to identify anti-static workbenches.
First of all, the anti-static workbench is guaranteed to have anti-static performance. Generally, the supplier will customize the anti-static workbench according to the size requirements, so you don't need to worry about this. Secondly, there must be an anti-static table mat and an anti-static grounding wire on the desktop. The bracket is made of anti-static material with a conductivity of 106Ω, so that the overall effect of anti-static. Finally, when testing, don't just test the anti-static index of the table, but check the anti-static performance and resistance to ground as a whole, because the overall anti-static function is to avoid the occurrence of static electricity from the source.
Also pay attention to when purchasing. Some factories use ordinary workbenches, but just put an anti-static table mat on the workbench surface. In fact, it is not advisable to do so. Although the table top meets the requirements of anti-static, but Static electricity cannot be discharged in time, and other parts of the ordinary workbench may also generate static electricity. Therefore, the entire desk should be sprayed with anti-static. A qualified anti-static workbench must meet the following three points:
1. The surface resistance of the overall paint surface spraying of the anti-static workbench must meet the anti-static requirements.
2. The overall grounding resistance of the anti-static workbench must meet the anti-static requirements. (Volume resistance from table top to table foot).
3. The surface resistance of the anti-static workbench must meet the anti-static requirements.
