What are the misunderstandings of ion fan selection? With the development of industrial technology and the improvement of product technology, the control of static electricity in production and manufacturing is becoming more and more strict. Among them, ion fan is one of the indispensable static elimination devices. Use the most common ionization equipment, especially in the semiconductor, panel and related industries in the 3C industry. But there are also many manufacturers of ion blowers, imported and local, high-end and low-end, intelligent and manual, DC and AC, etc., so many people will enter a misunderstanding of the choice of ion fan, the factory When purchasing an ion fan, the following four points are available for reference to prevent the purchase of an improper ion fan and suffer from loss.
What are the misunderstandings of ion fan selection?
Myth 1: The ion fan is a cutting-edge high-voltage discharge module, which is produced by any manufacturer.
Many factories' purchases may make this mistake. Of course, this can't be blamed. After all, the ion fan is only a negligible amount in some factories, and the purchase cost is negligible. Plus the buyer is not a technician, they think that the ion The fans are all the same, no difference. In fact, it is not like, some people think that the mobile phone assembly factory can only make a finished machine by buying all the accessories such as screen, soft board, camera, casing, battery, antenna, etc. The doorway of the ion fan is still quite a lot, different. The brand difference is still very big. For example, how much high voltage is needed to make the tip discharge, how much positive and negative ions can guarantee the reverse charging, whether the ion balance can be controlled within ±10V, etc., not all manufacturers can do it. These ones.

Myth 2: The ion fan is a consumable. Anyway, you have to change it and buy it cheaply.
Some factories directly locate the ion fan as anti-static consumables. They change for half a year or one year. At the same time, the procurement cost is controlled very low. The cheaper the more you like, the more you actually enter an infinite loop. The replacement frequency is more than the compression cost. Strictly speaking, the ion fan can not be counted as consumables. For small supporting equipment, the service life is determined by the on-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 crucial. . The discharge needle of the core part of the ion fan has steel needle, tungsten needle and silicon needle. The cost of the steel needle is a few cents, the second is the tungsten alloy needle. The price of the silicon needle is the highest. The current price/performance ratio is the tungsten needle. There is also a component. It is a high-voltage module. The cost of an ordinary transformer is only ten yuan. There is also a single-piezoelectric ceramic iron oxide. The high-pressure stability is good, and the cost ranges from tens to hundreds of yuan. Now it is better to upgrade to a bimorph ceramic. The manufacturer is the KESD of the mainland, and the SSD of Japan. Good quality will last long, and of course the price will be higher.

Myth #3: Ion fans don't need to be maintained and tested, and they can be put together to make them look like they are.
This is a common problem in many domestic enterprises. I think that the ion fan is only used when it is audited by its customers. Whether it is good or bad, or even a fan with only a hair dryer, it is extremely irresponsible. 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 does not necessarily affect it, so it is easy to ignore, but in the case of ESD, the defect rate of the product will increase or even exist. A higher quality hazard, this is not worth the candle. Moreover, the ion fan needs regular maintenance. Because the ionization equipment has a long discharge time, it will oxidize and adsorb dust, and the ion release amount will be weakened. The static elimination effect will be greatly reduced. However, there is a maintenance-free and maintenance-free ion fan on the market. Free to set the cleaning time. Ion fans are generally subject to monthly or quarterly inspections, depending on the condition of the plant, in order to ensure the effectiveness of the use.

Misunderstanding 4: Only imported ion fans can meet the high static elimination requirements, and domestically produced low-end products.
At present, China's industrial level has not yet reached the same level as the US, Japan and South Korea. After all, we still have to start decades later, but some brands of ion fans can still compete with imported ones, but most domestic manufacturers still All stay at the low-end machine level. Japan's Keyence should be the big man in this industry, followed by SMICO, SSD and Zen.

In addition to the price and quality of the ion fan at the time of purchase, it is also important to pay attention to the after-sales service. Imported products may be of good quality, but the supporting services may not be able to keep up. Equipment such as this requires at least two technicians to arrange on-site inspections by technicians every year, because the ion fan is abnormal and the production line is out of service. It will result in great waste of production and reduced production. Therefore, the ion fan must be considered clearly when selecting, identify the wrong zone to find the best cooperative brand.
