The quality of anti-static products and elimination equipment is in charge
In the electronics manufacturing industry, everyone’s fear is that static electricity cannot be eliminated, and everyone knows that static discharge will cause electrical stress damage to electronic components. The main culprit is that the instantaneous voltage of static electricity is very high, which can cause destructive and long-lasting damage. , How to make the static voltage low or unable to be generated? This is also a problem that everyone is most concerned about. Use anti-static consumables, anti-static elimination equipment, and do a good job of grounding static discharge, and preventive work is in place.
In actual work, many customers said that their layout in accordance with the ESD standard is very complete, but the actual situation is still not satisfactory, or some customers say that the ESD certification cannot be passed, and they have to investigate the cause again. During this time, the editor also analyzes with the customer. Many production lines have encountered static problems, and the result is that customers use anti-static products that do not meet industry standards. For example, the anti-static clothing used on the customer’s production line has been tested by an electrostatic field tester. The friction voltage exceeds a lot. The electrostatic clothing is made of conductive fabrics. Conductive fibers are added evenly and equidistantly into the fabric. The quality of the anti-static clothing worn by the workers is very poor, and the anti-static effect cannot be achieved.
Anti-static products are considered qualified in the minds of users, but in fact they are not so ideal. If you meet a good supplier, you can be convinced that the quality of the product is important, but it does not rule out that the product malfunctions or is routinely routine. Therefore, it is recommended that users know how to check the performance of the anti-static products used. If they are unclear, they can let the supplier provide technical support. Only effective product performance testing on the spot and in real time can they be used with confidence.
Static electricity is usually generated by humans, such as production, assembly, testing, storage, handling, etc., can cause static electricity to accumulate in the human body, instrument or equipment, and even the components themselves will also accumulate static electricity. Under circumstances, contacting these charged objects will form a discharge path, which will instantly damage electronic components or systems by electrostatic discharge. This is why it is necessary to wear an electrostatic bracelet on the work table to prevent electrostatic damage to the human body. Chips, just as the charge stored in the cloud instantly breaks through the cloud to produce violent lightning, which will split the earth apart, and it is usually when the rain comes, because the air humidity is easy to form conductive channels.
Common methods of neutralizing and eliminating static electricity in the working environment through ion blowers and ion wind rods. Whether these devices can meet industry standards, it is also necessary to use ion blower testers to detect their ion balance. In actual work, they have indeed encountered Many users who use ion blowers have not implemented the evaluation of the ion blower’s ability to eliminate static electricity. Although the effect can be achieved when the ion blower is newly purchased, after a long time of use, coupled with the impact of the working environment, the ion needle will There is dust, and the ion fan cannot 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 require the production site to comply with electrostatic industry standards. Before ESD certification, many customers will ask professionals to conduct ESD counseling before certification. In addition to listing a series of management systems, the focus is to discover To improve the problems existing in the production site, to find the problem, the basic project is mainly to test a series of indicators for ESD products, electrostatic grounding, and elimination equipment. For strict testing, instruments with the right to speak must be conducted, with accuracy and large range. , There is a certain reference value, so that the reflected problems can be upgraded and transformed in a targeted manner.
With the rise and popularization of the electronics industry, anti-static products have been used to a large extent, and the application fields of anti-static products are also more extensive, and the quality requirements for anti-static products are becoming more and more stringent. Due to the large demand in the commercial market With the increase, many businesses want to get involved in the field of anti-static products. With the entry of a large number of businesses, it is difficult to distinguish the quality of anti-static products. Only their own companies strictly control anti-static products, and earnestly implement ESD standards, anti-static products, and eliminate The quality of equipment depends on the supervision of testing equipment.
The anti-static products used in the elimination of static electricity and supervision rely on static detection equipment. Everyone knows that they are not willing to spend a small amount of money to protect the lifeline of the company's products? Only by thoroughly understanding the problems that exist on our own production lines can we have clear goals for the implementation of the ESD system and achieve good ESD protection.
