1. Misconceptions about Static Protection
Connecting the power zeroing, lightning protection grounding and static grounding to the same grounding source is an incorrect approach. Lightning strike and other phenomena can affect the performance of the product and personal safety through the circuit. When dealing with static electricity, using a humidifier to increase humidity. If this method is adopted for a long time, the water film will gradually have chemical effects on the components in the environment, accelerating the rusting of metal parts and causing short circuits in the components.
In terms of anti-static treatment, wearing anti-static shoes is an indispensable step. However, people pay less attention to the choice of socks. Thick woolen blankets in winter can affect the anti-static effect.
2. Existing Problems
Composite conductive panels are decorative panels mixed with internal additive anti-static agents. Their conductivity is poor and not long-lasting due to the constraint of ions. Rubber panels with conductive fillers, mainly containing conductive carbon black, have poor color and wear resistance. Polymer panels with conductive fibers or other conductive fillers as the main component are made of polyvinyl chloride (PVC), have good conductivity, wear resistance, acid and alkali resistance, and are relatively stable. The color is acceptable, but the process is complex and the cost is high. Products that simultaneously meet high conductivity, good color, good durability, good processing performance and low cost still await technological progress.
Flooring panels. The surface of the currently produced floor panels in China is usually made with steel, aluminum, plastic or wood as the base material, and is covered with a decorative panel containing internal additive anti-static agents as the surface layer. The drawback is that the conductivity of the surface layer is not yet sufficiently durable. The surface layer must ensure that it can quickly conduct away the static electricity of the human body, and the durability of the conductivity needs to be greatly improved. The bonding between the base material of the panel surface and the surface layer should use conductive glue, and the glue should have high adhesion and certain elasticity. The common defects at present are that the surface layer翘起或开裂.
Electrostatic protection in the production process of electronic products covers the entire process from the selection and ordering of electrostatic-sensitive components, factory acceptance inspection, storage, assembly and welding into products, to debugging and packaging. It involves the participation and cooperation of various departments and personnel in technology, management, production, etc. Electrostatic protection is a comprehensive systematic project. Only when leaders attach importance to it, all parties participate, and there is a strong awareness of electrostatic protection can significant protective effects be achieved and losses be reduced.
