Product name = Ion Blade

Uniform elimination of static through ions generated on a surface, not on a point

Manufactured by FISA Corporation, Ion Blade is a static eliminator that removes and neutralizes static electricity on a substance by generating ions from electrodes across an entire surface. Since the ions are generated on a surface instead of in points, uniform elimination of static electricity is possible. Furthermore, the required voltage has been halved compared to conventional products, and the electrostatic attraction of dust has been significantly reduced. As a result, in addition to extending the period during which static elimination capability is maintained, Ion Blade also reduces the frequency of cleaning. Maintenance costs are reduced to about 1/40 of existing products made by FISA.

Even more, Ion Blade is bendable. This means that it can formed into various shapes to match production equipment and on-site characteristics. For example, it can be affixed to substrates or in gaps, or can be formed into a circular ring (Photo 2).

Solving issues of conventional products that attract dust at high voltage

In the case of conventional static eliminators called corona discharge eliminators, a high voltage is applied via a needle-shaped electrode*. Ions are generated at single points, not across a surface. This method was previously used by FISA. It required a high voltage of 4,000 to 7,000 volts and created an issue in which surrounding dust was attracted by the high voltage. In addition, there was the disadvantage of requiring frequent cleaning that was difficult to perform. These conventional eliminators were not suitable for eliminating static electricity in narrow spaces.

The solution to these problems is the "dielectric barrier discharge method" recommended by the National Institute of Advanced Industrial Science and Technology. This method can generate ions at a voltage of 1,000 to 3,000 volts. By adopting this method for static eliminators, FISA has solved various issues such as optimizing the shape, developing power supplies, and reducing manufacturing costs. The result was Ion Blade, which is about 5 mm thick and is composed of microelectrodes made of stainless steel on a mica material dielectric. The product successfully reduced the electrostatic attraction of dust. Ion Blade can also be used to remove static electricity in narrow places and close-set locations. It is suitable for integration in automatic inspection equipment and transport equipment, such as proximity static electricity in the transport process of paper, film, and glass substrates, which were difficult areas to address when using conventional static eliminators.

Looking to sell electrodes and power supplies as individual products

Until now, FISA has released fan-type and bar-type devices equipped with Ion Blade. However, in order to accommodate narrow spaces and close-set locations where it is even more difficult to install a static eliminator, the company is considering selling electrodes and power supplies as individual products. If such sales are realized, FISA will be able to integrate Ion Blade into visual inspection equipment, separation machines, taping machines, small printers, etc.

Ion Blade is expected to contribute to the achievement of high-efficiency production lines and create high added value in various devices.
