Correct understanding of ionizers

Various types of ionizers  |  Correct understanding  |  Attention!  |  Key points for ionizer selection  |  Application examples of TRINC
1. Static eliminator (ionizer) has a possiblity to generate static electricity.
Low quality ions from low quality ionizer generate static electricity.
Here, low quality means bad ion balance.
This fact may be not well known generally, but electrostatic charge by ionizer occurs more or less in some cases.
1) Ion balance of pulse type ionizer

The ion balance of AC pulse type and DC pulse type ionizers pulsates at a pulse frequency, even ut to ±500V.
Use of these types of ionizers can damage electronic or semiconductor devices that are not tolerant against statics electricity.
2) Ion balance of DC type ionizer

There is no pulsation of ion balance when using DC type ionizers, unlike AC pulse type ionizer. Since the ion balance of DC type ionizers depends of position, it should be used in the proper position, so that the good ion balance within ±3V. Therefore, this type of ionizers can be said to be suitable for static removal from fragile electronic or devices and semiconductors.
    TRINC's ion-engine type ionizer is an evolution of the DC type ionizers, that has the similar principle to the propulsion engine of space probe "Hayabusa".

2. Static eliminator (ionizer) destroys semiconductor!?
1) Be aware of ion balance pulsation!

AC pulse type and DC pulse type ionizers emit positive and negative ions alternately in frequency of ~30Hz. So, the object is repeatedly exposed to positive and negative ions one after another, repeatedly.
    This phenomenon is called ion balance pulsation, that is hated and avoided. There are AC pulse type and DC pulse type ionizers with the ion balance pulsation of up to ±500V. These types of ionizers has inherent risk of destruction of electronic device or semiconductor.
3. Impossible to remove satic electricity to 0V using pulse type static eliminator !?
1) Decay time

Due to the ion balance pulsation of AC pulse type and DC pulse type ionizers, the static electricity on object exposed to it cannot be neutralized forever.

4. Maintenence of static eliminator
1) Maintenance of discharge needles

If ionizers don't have sufficient resistance to high voltage, electric leakage occurs inside them, and the insulator (plastic) that fixes the discharge needle is burnt and carbonized. Since the carbonized part can't be removed using brushes, it should be cleaned with a solvant.
    On the other hand, TRINC's ionizers have no-leak structure and free from carbonization of parts around discharge needles. TRINC's one-touch cleaner mechanism enables instant cleaning of discharge needles within a few seconds. If the automatic cleaner is selected, the cleaning is completed more easily automatically.

5. Keys for success are "No-blow ionizing",
  "Space ionizing using phased array ionizer", and "No-leak structure".
1) No-blow ionizing

The no-blow ionizer generates ions by corona discharge and fly ions away using the repulsive force between the ions and the discharge needles. Since air blow is not used, there are no scattering of foreign matter around so that the surrounding clean environment never be destroyed. Of course, foreign matter adhering to discharge needles is not blown to the products.

2) Space ionizing using phased array ionizer

"Phased array ionizer" that enables space ionizing fills the wide space with ions. The amount of positive and negative ions are controlled to be same. All of static electricity existing in the target space, including that on products, equipment, humanbody, and dust, is neutralized by these ions.
    Conventional ionizers are used to remove static electricity on products and parts, and can not remove static on dust floating in the air. The dust adhesion is caused by the Coulomb's attractivce force between objects (products or parts) and the dust. So, the removal of static electricity from both objects and dust is necessary to prevent dust adhesion.
    The function of the phased array ionizer that the static electricity of dust is also removed leads to drastic decrease of dust-related defects. There is a actual case that the defects were decreased by 92%.

3) No-leak structure

There is a fundamental rule in the electric engineering that "Air flow channel and high voltage parts should not exist in the same space". Even with a 100V power supply, we are afraid of a tracking phenomenon, that is a electric leakage occured by dust. So, of course, the static eliminator that generates ions using a high voltage of several kilo-volt must be serpareted with easily fog-containing air to avoid electric leakage.
    TRINC's ionizers have the structure in which the high voltage part and the air flow channel are separeted each other, that is "no-leak structure". This no-leak structure makes it possible to extend the lifetime of TRINC's ionizers and realize the overwhelming record of toughness free from abnormality even after using 10 years.
