Materials that do not easily transfer electrons are called insulators or non-conductors. An insulator will hold the charge and cannot be grounded; therefore the charge cannot dissipate in a controlled way. This could lead to static damage of nearby sensitive components as there can be a rapid, spontaneous transfer of electrostatic charge.
Insulators can be controlled by doing the following:
- Keep insulators a minimum of 30cm from ESDS items at all times, or
- Replace regular insulative items with an ESD protective version, or
- Periodically apply a coat of topical antistat.
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.
Ionisers can neutralise static charges on an insulator in a matter of seconds.
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.
We offer a wide product range of ionisers: bench-top, overhead and compressed air/gas point of use. Our products incorporate superior technology providing fast charge decay times, and such features as auto balancing offset voltage feedback controls and "clean me" alarms.
