Anti-static products, ESD equipment quality
Everyone in the electronics manufacturing industry is most afraid of the fact that static electricity cannot be eliminated, and everyone knows that electrostatic discharge will cause electrical stress damage to electronic components. Because the instantaneous voltage of static electricity is very high, it will cause devastating and long-term damage. How do you make the static voltage low or impossible? This is also a problem that everyone is concerned about, use anti-static supplies, anti-static elimination equipment, do a good job of static ground discharge, preventive work to do.
In actual work, many customers said that they are very complete in accordance with the ESD standard layout, the actual situation is still unsatisfactory, or some customers say that ESD certification can not pass, but also have to re-examine the reasons, this time Xiaobian also analyze with customers Many production lines have encountered the problem of static electricity. As a result, customers have used anti-static products that do not meet industry standards. For example, anti-static clothing used on customer production lines. After testing by electrostatic field tester, the friction voltage is much higher. The manufacture of the electrostatic clothing is produced by a cloth having a conductive function, and the conductive fibers are evenly and equidistantly placed in the cloth. The quality of the antistatic clothing worn by the worker is poor, and the antistatic effect is not achieved.
Anti-static products are considered to be qualified in the user's mind, but they are not so ideal. It is convincing that a good supplier pays attention to the quality of the product, but it does not rule out that the product is malfunctioning during the operation or routinely routine. Testing, it is recommended that users should know how to check the performance of anti-static products used. If there is any unknown, you can let the suppliers provide technical support. Only in-situ, real-time effective product performance testing can be used with confidence.
Static electricity is usually generated by humans. In the process of production, assembly, testing, storage, handling, etc., static electricity can accumulate in the human body, equipment or equipment, and even the components themselves will accumulate static electricity when people are unaware of In this case, the contact of these charged objects will form a discharge path, which will cause the electronic components or systems to be damaged by electrostatic discharge. This is why the maintenance computer must wear an electrostatic wrist strap on the work table to prevent static damage of the human body. The chip, like the charge stored in the cloud, instantly breaks through the clouds and produces intense lightning, which will open the earth, and it is usually on the rainy day, because the air humidity is too high to form a conductive path.
Ion fans and ion wind bars are used to neutralize the common methods of eliminating static electricity in the working environment. Whether these devices can meet the industry standards, they also need to detect their ion balance by the ion fan tester. In reality, they have actually encountered Many users who use ion fans do not evaluate the ability of the ion fan to eliminate static electricity. Although the ion fan can be used when it is newly purchased, after a long period of use and the influence of the working environment, the ion needle will Dust, the ion fan can not achieve the normal effect of eliminating static electricity, the static elimination equipment should be tested regularly to ensure the normal use of the equipment.
The purpose of ESD certification is to strictly meet the requirements of the static industry standards. Before ESD certification, many customers will ask professionals to conduct ESD counseling before certification. In addition to a series of management systems, the focus is to discover The problems existing at the production site are improved, and the problem is found. The basic project is mainly to test a series of indicators for ESD products, electrostatic grounding and elimination equipment, and to perform strict testing on instruments that must have the right to speak, accuracy, and large range. There is a certain reference value in order to make the reflected problems and upgrade the production line in a targeted manner.
With the rise and popularity of the electronics industry, anti-static products have been applied to a large extent, anti-static products are also widely used, and the quality requirements for anti-static products are becoming more and more strict, due to the large demand in the commercial market. Increase, many businesses want to get involved in the field of anti-static products, the entry of large-scale businesses, the quality of anti-static products is difficult to distinguish between good and bad, only their own enterprises to strictly control anti-static products, earnestly implement ESD standards, anti-static products, eliminate The quality of the equipment depends on the supervision of the testing equipment.
Excluding static electricity and the anti-static products used in supervision rely on static electricity detection equipment. Everyone knows why, why not want to spend a little money to protect the lifeline of the company's products? Only by thoroughly understanding the problems existing in the production line can the implementation of the ESD system have clear objectives and achieve good ESD protection.
