How to carry out the anti-static workbench installation test
There are two main reasons why the anti-static workbench has anti-static function, one is because the anti-static table mat is placed on the desktop; the other is because of the anti-static grounding wire. If the workbench lacks a grounding wire, it will not be able to prevent static electricity. The antistatic grounding wire means to release all the static electricity generated by the antistatic workbench on the ground. So, how does the anti-static workbench installation test work?
1. Working principle of anti-static workbench
To understand the anti-static workbench installation test, you must first understand its working principle. The countertop of the anti-static workbench is made of anti-static melamine high-pressure decorative laminate as the surface material and the wooden material. Generally speaking, the wood material is particle board. If the conductor is embedded and grounded through the ground wire, the static charge on the table surface can be discharged to the ground through the wire.
In addition, there is a workbench of a material called a stainless steel workbench, which is mainly to lay an anti-static table mat on the table top, and then the table mat can be connected to the earth through a wire, so as to achieve the effect of discharging static electricity.
2. Introduction to the structure of anti-static workbench
The main frame of the anti-static workbench is generally made of aluminum material, and the table is made of anti-static fireproof board or anti-static table mat. This material has two functions, very good grounding measures, and very good anti-static effect. Under the main frame, there is a free adjustment foot, which can adjust the height of the workbench, which is very convenient.
Three, anti-static workbench installation test
1. Perform surface impedance testing
The specific operation method is to take four points on the desktop, and then proceed according to the picture. Take out the two poles of the static electricity detector and place them in the specified positions, test static electricity while recording the results.
2. Perform ground impedance detection
The specific operation method is to take four points on the desktop, and then proceed according to the picture. Take out one pole of the static electricity detector and place it on the specified position. While testing the static electricity, record the result, only record one point, and record according to the maximum resistance value. .
3. Perform regular frequency testing
If it is a newly installed anti-static workbench, it will be tested about once every six months, and the qualified range is 106～109.
Now everyone knows about the installation test and working principle of the anti-static workbench! So, when you are installing and testing the anti-static workbench, you may wish to refer to it to achieve a better use effect.
