How to tell when the anti-static table mat needs to be replaced
The surface resistance standard of the anti-static table mat in the electronic workshop is between the 6th power of 10 and the 9th power of 10 ohms, and the bottom surface resistance is between the 3rd power of 10 and the 6th power of 10 ohms, but when the anti-static table mat When the surface resistance detection data is higher than the 9th power of 10, does it mean that the anti-static mat has failed?
In fact, not necessarily, we have to learn to find the real reason why the resistance does not meet the standard, and avoid increasing the cost of replacing the pad. One possibility is that dust has accumulated on the surface layer of the table mat. Dirt and dust can hinder the conduction of static electricity. If it is, it is very convenient to handle. You can wipe it with clean water and then measure it. Another possibility is to check the anti-static work. Whether the table is grounded, test the volume resistance, if the data is not up to standard, you can replace the anti-static table pad.
