What are the misunderstandings of the ion fan selection?
What are the misunderstandings in the selection of ion fans? With the development of industrial technology and the improvement of product technology, the control of static electricity in production is becoming more and more strict. Among them, ion fans are one of the indispensable static elimination equipment. The most common ionization equipment is used, especially related industries in the semiconductor, panel and 3C industries. However, there are many manufacturers of ion fans, imported and local, high-end and low-end, intelligent and manual, DC and AC, and so on, so many people will enter a misunderstanding of ion fan selection, factory When purchasing an ion fan, the following four points can be used as a reference to prevent you from being fooled by purchasing an inappropriate ion fan.
Misunderstanding 1: The ion fan is a cutting-edge high-voltage discharge module, which is the same for any manufacturer.
Many factories may make this mistake in purchasing. Of course, this can not be blamed. After all, the ion fan is only a trivial amount in some factories, and the procurement cost occupied can be ignored. In addition, the buyer is not a technician. The fans are all the same, no difference. In fact, otherwise, just like someone thinks that a mobile phone assembly factory can only make a finished machine by buying all the accessories such as screens, flexible boards, cameras, housings, batteries, antennas, etc. There are still many doorways for ion fans, different There are still big brand differences, such as how much high voltage is required to allow the tip to discharge, how much positive and negative ions can be guaranteed to not be reversely charged, whether the ion balance can be controlled within ± 10V, etc., not all manufacturers can do it. These ones.
Misunderstanding 2: Ion blowers are consumables. Anyway, you need to change them.
Some factories directly position ion blowers as anti-static consumables, and change them every six months or a year. At the same time, the purchase cost is controlled very low. The cheaper the more, they like it. In fact, it has entered an endless cycle. There is no compression cost for more frequent replacement. Strictly speaking, the ion fan cannot be regarded as a consumable. It is a small supporting device. Its service life is determined by the site environment and frequency of use and the quality of the ion fan. The environment and frequency cannot be changed. The quality of the ion fan is very important. .
Misunderstanding 3: Ion fans do not need to be maintained and tested.
This is a common problem of many domestic enterprises. I feel that the ion fan is only used in the audit of its customers, regardless of its quality, or even a fan that only blows air. This is an extremely irresponsible approach. The purpose of the ion fan is to prevent the occurrence of electrostatic discharge. Although the effect of static electricity on the product is not visible to the naked eye, it is not necessarily affected, so it is easy to ignore, but once ESD occurs, the defective rate of the product will increase or even exist Higher quality risks are not worth the money. Moreover, the ion fan needs regular maintenance. Because the ionization equipment tip discharges for a long time, oxidative adsorption dust will appear, the ion release will decrease, and the effect of removing static electricity will be greatly reduced. However, there are now maintenance-free and maintenance-free ion fans on the market. Free to set cleaning time. Ion blowers are generally inspected monthly or quarterly, depending on the conditions of the factory, so as to ensure the effectiveness of use.
