Have you chosen the right static elimination product
The static electricity on the equipment or the human body can be as high as tens of thousands of volts to hundreds of thousands of volts, and it often reaches hundreds to thousands of volts under normal operating conditions. The human body is separated and rubbed due to its own actions and contact with other objects. Or induction and other factors, it can bring thousands of volts or even tens of thousands of volts of static electricity. Static electricity is the result of the loss of balance between positive and negative charges in a local range. It is a kind of electrical energy that remains in the object. It has high potential, low electricity, Features of low current and short action time.
The main measures of static control include: static leakage and dissipation, static neutralization, static shielding and grounding, humidification, etc.
The transfer and storage of electrostatic sensitive components and printed circuit boards during the production process must use anti-static feeding boxes, component boxes, turnover boxes, turnover trays, etc. to prevent the hazards caused by static electricity accumulation. As a finished product When packaging, anti-static shielding bags, packaging bags, packaging boxes, baskets, etc. must be used to avoid static electricity damage during transportation.
In the production process of electronic products, its components, components and finished products often contact, separate, and rub with equipment tools, etc., which generate static electricity. Anti-static cushions, turnover carts, maintenance kits, tools, work chairs, etc. must be used, and appropriate The grounding can quickly discharge static electricity.
Friction electrification and human body static electricity are the two major sources of hazards in the electronics and microelectronics industries, but the generation of static electricity is not the hazard. The hazard is the accumulation of static electricity and the resulting electrostatic charge discharge. The charged objects form an electrostatic field around them. It will produce mechanical effects, discharge effects and electrostatic induction effects, so it must be controlled.
Due to the mechanical effect of static electricity, floating dust particles in the air will be adsorbed on silicon chips and other components, which will seriously affect the quality of electronic products. Therefore, anti-static measures must be taken for the clean room. Walls, ceilings and floors of clean rooms, etc. Anti-static materials that do not emit dust should be used, and a series of electrostatic protection measures should be taken for operators, workpieces, and appliances.
In order to understand the static electricity in the production process, determine the degree of static electricity in the production process, and inspect the quality of electrostatic protection products and equipment, it is necessary to measure static electricity and related parameters.
The measurement of static electricity is mainly to measure the static voltage, material resistance, ground resistance, static off-life, static electricity, static elimination performance, and surface density of cloth charge.
The electrostatic protection work is a systematic project, and any omission or error in any link will lead to the failure of the electrostatic protection work. It must be guarded from time to time, and everyone is guarded.
Static elimination products have a wide variety according to different use environments and specific uses. According to the styles, there are fan-type ion fans, dust-removing ion pine, ion wind nozzles, ion wind snakes and ion rods with and without air pressure. Faced with so many types of static elimination products, which one is suitable for your factory? What are the selection criteria?
In the end, which static elimination products should we choose? The main basis is to look at the specific needs of the production process of the factory and the characteristics of the workplace. For example, a rod-type static eliminator without air pressure is required in a machine with an FFU high efficiency filter. (For details, please enter "Ion Wind Stick" in "Product Center"). Static elimination on the workbench can choose desktop or suspended static elimination products according to the scope of static elimination. If you need to remove dust, you can choose ion fan, dust-removing ion dolo, ion wind nozzle, ion wind snake and ion rod; generally speaking, ion rods are commonly used in the printing and textile industry; metal, spraying, blister and other industries use ions Fan, dust-removing ion dosson, ion wind nozzle, ion wind snake.
All in all, when choosing static elimination products, you should start from your own process requirements and make a choice of products according to their working place. Different industries have different requirements for product use, performance, and installation methods.
