Routine service is typically required to meet quality audit requirements.” (User Guide CLC/TR 6 clause 4.7.6.7 Maintenance and cleaning)ĮIA-625, recommends checking ionisers every 6 months, but this may not be suitable for many programs particularly since an out-of-balance may exist for months before it is checked again. It is important to set-up a routine schedule for ionizer service. Critical clean room uses will generally require more frequent attention. Maintenance intervals for ionizers vary widely depending on the type of ionization equipment and use environment. “ All ionization devices will require periodic maintenance for proper operation. Below we have put together a list of tasks that need to be performed with ionisers on a regular basis. It is therefore essential to regularly clean ionisers and verify their functionality. This results in placing an electrostatic charge on items that are not grounded, potentially discharging and causing ESD damage to nearby sensitive items. However, if an ioniser is out of balance, instead of neutralising charges, it will produce primarily positive or negative ions. The only way to control charges on these necessary non-conductive items is the use of ionisation systems. This is not always possible because some insulators are “process-essential” and are necessary to build or assemble the finished product.

The best way to keep electrostatic sensitive devices (ESDs) from damage is to ground all conductive objects and remove insulators from your ESD Protected Area (EPA).
