The benefits of anti-static in microelectronics and other fields
For companies in fields such as microelectronics, the benefits of antistatic treatment of production environments are obvious. First of all, the most obvious thing is cost control. After anti-static treatment of the working environment, the yield rate of products will increase significantly, or the rate of defective products can be minimized as much as possible. At this time, unnecessary expenses incurred by the enterprise due to defective products will be reduced as much as possible.
Secondly, it is the shaping of the corporate image. When customers come to visit, they can see a professional and well-planned production environment, which can establish an image of seriousness and responsibility and excellent quality in the eyes of customers, laying the foundation for further cooperation.
The most important thing is to maintain the brand reputation. Many microelectronic components are often not scrapped immediately after being damaged by static electricity, but can still work normally within a certain period of time, which often leads to the appearance of new products purchased by customers within a short period of time. The problem is even completely scrapped, causing damage to the reputation of the enterprise, and the anti-static treatment of the working environment can prevent this situation to the greatest extent and maintain the image of the enterprise in the minds of customers.
How to prevent static electricity?
Microelectronics electrostatic protection:
Operators: People are the biggest source of static electricity. People's movement and work will generate static electricity, and electrostatic discharge may be generated when they are in contact with or approaching microelectronic devices. To reduce the personnel factor, you must wear anti-static clothing, gloves and anti-static shoes, wear anti-static wrist/foot rings and be grounded reliably. Develop good working habits and stay away from static-sensitive products without anti-static measures or incomplete measures.
Equipment: In order to improve the production capacity of enterprises, automation equipment is used in many processes, and the operation of these equipment will generate a large amount of static electricity. In the processing of microelectronic devices, various processes will release static electricity, and a large number of microelectronic devices will fail. All equipment, instruments, workbenches, stools, shelves need to be reliably grounded. Mobile turnover trolleys, etc. should also be connected to the ground by installing electrostatic discharge.
Materials: Use antistatic/conductive materials to make work surfaces, turnover/packing boxes in the operating environment.
Environment: The generation of static electricity is proportional to the ambient humidity, that is, the greater the humidity, the less static electricity is generated. However, the high humidity environment is easy to cause rust and corrosion. Considering it comprehensively, the humidity of the general electronic production workshop is kept at 30%-70%RH. Alternatively, an ion fan can be used to neutralize static charges.
