How to check the performance of the ion fan
How to check the performance of the ion fan? At present, the ion fan is widely used in electronics production, LED light emitting diodes, LCD liquid crystal displays, LCM liquid crystal display modules, medical instrument assembly and packaging industries, and chemical, printing, plastic, and other industries. If the ion fan fails, it will directly affect the quality of the product. Therefore, to ensure that the ion fan is used normally, to achieve the purpose of removing static electricity, the performance of the ion fan must be tested at the time of purchase and during use. In this article, Runfengyuan Electronics introduces how to detect the performance of the ion fan?
Nowadays, the domestic ion fan market is relatively chaotic, and various brands are plentiful. Even professionals in the ESD monitoring department can hardly judge the quality and performance of an ion fan, because almost all ion fans are now It has similar functions. It can eliminate ions to within ± 10V within 1 second on paper, more within ± 5V, and the appearance and principle are the same. Therefore, it is necessary to conduct field inspection and identification of the ion fan to Determine its performance.
How to check the performance of the ion fan? It is difficult to judge the appearance of the ion fan, especially for the products that have just left the factory. The efficiency of releasing ions is invisible and untouchable. You can choose a handheld electrostatic detector. Select some products that are prone to static electricity. If it is not possible to generate hundreds of volts of static voltage at the moment of friction, use a detector to test the changes before and after the ion fan blows, and the speed of change, although it cannot be measured accurately. Static electricity and balance voltage, but it can be a good reference. The ion fan with good effect can quickly reduce the static electricity to 30V or even lower, and its fluctuation is more stable.
How to check the performance of the ion fan? In fact, the ion fan has a balanced voltage. This balanced voltage is measured by the ion fan tester test kit. The balanced voltage is an important performance of the ion fan! It reflects the working time of the ion fan. The electrostatic hazard that will be brought to the object, that is, the static voltage that will be generated on this object. If this voltage does not exceed the antistatic capability of ESD sensitive devices, it is safe. The current ion fan balance voltage can only be a few volts, so it is safe for most cases.
Ion blower is the key equipment in the factory to prevent static electricity from interfering with normal operation, so its quality and performance are very important. A slight negligence will cause serious intervention.
