The quality of anti-static products or equipment
In the electronics manufacturing industry, everyone is afraid that static electricity cannot be eliminated, and everyone knows that electrostatic 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 devastating and long-lasting damage. How to make the static voltage low or unable to be generated? This is also the issue that everyone is most concerned about. Use anti-static consumables, anti-static elimination equipment, and do a good job of electrostatic grounding and 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. The actual situation is still not satisfactory, or some customers say that the ESD certification cannot be passed, and they have to re-examine the reasons. During this period, the editor will also analyze with the customers. Many production lines encountered static problems, and the result was that customers used anti-static products that did not meet industry standards. For example, the anti-static clothing used on the customer’s production line was tested by an electrostatic field tester. The friction voltage exceeded a lot. The electrostatic clothing is made of fabrics with conductive function. 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 cannot achieve the anti-static effect.
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 fails during the operation or is routinely routine Therefore, it is recommended that users know how to check the performance of anti-static products used. If they are unclear, they can ask the supplier to 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 the circumstances, contacting these charged objects will form a discharge path, which will instantly damage electronic components or systems by electrostatic discharge. This is why you must wear an electrostatic bracelet on the work table to prevent the human body from electrostatic damage. Chips, just as the charge stored in the cloud instantly penetrates 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 to neutralize and eliminate static electricity in the working environment through ion blowers and ion wind rods. Whether these equipment can meet industry standards is also 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 and the influence 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.
