When do you need ionisation?
The primary function of an ioniser is to neutralise electrostatic charges on insulators and isolated (non-grounded) conductors to reduce the magnitude of electrostatic discharges in the ESD protected area.
A common example of insulators and isolated conductors is a populated circuit board where the board is a process essential insulator and often components on the board are isolated (non-grounded) conductors. Most companies handling electronics have such sub-assemblies in their products.
Also as electronic components become more ESD sensitive, many companies will want to add ionisers to improve their previously acceptable ESD control program.
If the ESD control program has not used ionization then that should be considered. If the ESD sensitive items becomes charged, ionization will help neutralize the charge. The primary function of ionizers with regard to ESD sensitive items include:

Why are ionizers important to use?
The most significant environmental factor in ESD Control is the relative humidity (Rh). When humidity in the working environment decreases, the human body and other insulators can easily charge with static electricity due to friction. The air itself, being dry, becomes a part of the electrostatic build-up mechanism, every time an air flow (wind, air conditioning, blower) come over an insulated surface. Relative Humidity shall be maintained over 30%. Below that value it is recommended the use of ionization.
Conductors: Materials that easily transfer electrons (or charge) are called conductors and are said to have “free” electrons. Some examples of conductors are metals, carbon and the human body’s sweat layer. Grounding works effectively to remove electrostatic charges from conductors to ground. However, the item grounded must be conductive.
Insulators: Materials that do not easily transfer electrons are called insulators and are by definition non-conductors. Some well known insulators are common plastics and glass. An insulator will hold the charge and cannot be grounded and “conduct” the charge away.
Both conductors and insulators may become charged with static electricity and discharge. Grounding is a very effective ESD control tool; however, only conductors (conductive or dissipative) can be grounded.
Insulators, by definition, are non-conductors and therefore cannot be grounded. Insulators can be controlled by doing the following within an EPA:
When none of the above is possible, the insulator is termed “process essential” and therefore neutralisation using an ioniser should become a necessary part of the ESD control programme. An ioniser creates great numbers of positively and negatively charged ions. Fans help the ions flow over the work area. Ionisation can neutralise static charges on an insulator in a matter of seconds, thereby reducing their potential to cause ESD damage.
Note: Ionisers require periodic cleaning of emitter pins and the offset voltage must be kept in balance. Otherwise, instead of neutralising charges, if it is producing primarily positive or negative ions, the ioniser will place an electrostatic charge on items that are not grounded.

How do ionizers work?
Air Ionization systems work by flooding the atmosphere with positive and negative ions. When the ionized air comes in contact with a charged surface, the surface attracts ions of the opposite polarity. As a result the static electricity that has built up on products and equipment is neutralised. Ions do remove small particles or smoke and pollens from the air, and subjective research suggest that people working in ionized area are happier.
Bondline’s ionizers eliminate the build-up of static charges on non-conductors, ensuring a static-free work area. Ionizers generate positive and negative ions which neutralise any static charges on insulating materials which cannot be grounded in the normal way. They are ideal for electronics industries which work with static-sensitive electrical components or devices.
