Whether the anti-static mat of the anti-static trolley should be grounded
The anti-static mat needs to be effectively grounded under any circumstances, otherwise it is just a decoration. Of course, the so-called "effective grounding" does not necessarily mean connecting a wire directly to the ground from the anti-static mat. If the trolley itself is grounded and the anti-static mat can be turned on, the anti-static mat does not need to be grounded separately.
How to verify the conduction of the anti-static mat? First of all, the trolley must have at least one ESD wheel, place the wheel on a metal conductor plate, spread the anti-static mat on the trolley, and use an ohmmeter to check whether the resistance between the surface of the anti-static mat and the metal conductor plate meets the requirements. If no, you can try to install a wire between the anti-static mat and the ESD wheel. If the answer is still no, then it is recommended that the trolley be equipped with a metal mop chain and connected to the anti-static mat with a wire to ensure the anti-static performance of the anti-static mat.
