How to prevent static electricity on the workbench?

Workbench is a commonly used product in the laboratory, but in our daily life and work, how to correctly prevent static electricity and use anti-static products is currently a concern for us Of course, there are many types of anti-static materials and products, but they can mainly be classified as anti-static mats, anti-static tools, etc. Firstly, to fundamentally prevent static electricity from the human body, the following anti-static products should be used:
1、 Anti static clothing and anti-static wrist straps
Anti static clothing and wristbands are important components of the human anti-static system, which can eliminate or control the generation of human static electricity, thereby reducing the main source of static electricity in the manufacturing process.
Anti static clothing includes anti-static jumpsuits, anti-static split suits, anti-static coats, anti-static shoes, hats, anti-static gloves, anti-static finger cots, anti-static wrist straps, etc. Anti static clothing is made of anti-static fabrics of different colors. Fabric yarn contains a certain proportion of conductive yarn, which is made by blending a certain proportion of stainless steel fibers or other conductive fibers with ordinary fibers. Eliminate static electricity on clothing through the corona discharge and leakage effect of conductive fibers. Due to the metallic nature of stainless steel fibers, the conductivity of anti-static fabrics woven from them is stable and does not change with the number of times the clothing is washed.
Anti static wrist strap is the most important anti-static product for operators when in contact with electronic components. Through the grounding path, it can safely discharge the static charges carried by the human body. It consists of anti-static elastic band, movable buckle, and spring cord Composed of protective resistors and plugs or clamps. The inner layer of the elastic band is woven with anti-static yarn, and the outer layer is woven with ordinary yarn.
2、 Anti static packaging and transportation products, etc.
There are many anti-static packaging products, such as anti-static shielding bags, anti-static packaging bags, anti-static sponges, anti-static IC packaging tubes, anti-static component boxes, anti-static turnover boxes, anti-static bubble films, and anti-static transport vehicles. Most of these packaging products are made of static dissipative materials, while others are made of anti-static materials. The purpose is to provide electrostatic protection for the installed circuits, devices, and printed circuits.
3、 Anti static flooring and anti-static table mats
Anti static flooring and anti-static mats are also indispensable in electrostatic protection engineering. There are also various types of anti-static floor mats, classified according to their timeliness, including permanent and temporary ones; Classified by material, there are conductive rubber PVC、 Conductive ceramics, etc; According to the laying method, there are raised floors that are directly laid on the ground and those that are elevated. It can be determined based on actual needs and costs. If multiple cables and pipelines need to be laid on the ground in environments such as computer defense, it is better to choose elevated flooring.
Anti static table mats are mainly composed of anti-static composite rubber plates, which are mainly used to pad tabletops, assembly line workbenches, shelves, and make floor mats. The material surface layer is divided into grass green color, and the conductive substance is anti-static agent; The bottom layer is black, and the conductive material is carbon black.
In addition to the three major categories of products mentioned above, there are also other anti-static products such as anti-static soldering irons, anti-static chairs, anti-static repair kits, etc. Anti static soldering iron is commonly used in post-processing and maintenance. General electric soldering irons require unplugging the power supply when soldering static sensitive components, while anti-static soldering irons use DC temperature voltage power supply. Heating elements are often made of materials with constant temperature characteristics and small electrostatic capacitance, which can greatly reduce various interference signals. In addition, the soldering iron can also be used for electrostatic grounding, which can further eliminate various signals on the soldering iron tip. So, there is no need to unplug the power plug during welding.
