There are many types of static eliminators in terms of principle and structure, and they have advantages and disadvantages, respectively.
• You can’t feel the effect of static elimination.
• Contrary to aim, the defect rate increases after introducing the ionizer.
• The ionizer itself breaks easily.
• Troublesome or impracticable maintenance.
• Hazardous for semiconductor.
• Risk of fire or electrical shock.
To avoid the disastrous situations described above, we would like to show a table summarizing the features of each ionizer type from technical point of views. We hope it will be provided to you as useful reference.
