In recent years, copper foils have been required to have higher quality in applications such as lithium ion batteries and printed wiring boards for mobile phones. There is a need to improve the effect of cleaning. Before removing the cutting oil or swarf on the copper foil surface with a cleaner, eliminating static electricity from the foil improves the effect of cleaning.
- It cannot eliminate static electricity, and increases the charge instead, causing secondary adhesion.
- The surface may be scratched by contact.
Countermeasures with static eliminators (ionizers)
The combination of an ultrasonic cleaner and a static eliminator allows cleaning and static electricity elimination without contact, which improves the effect of cleaning.
$9,000/half year x 2 = $18,000/year
In addition, there will be more cases where foils are made thinner, so conventional contact type cleaners cannot be used. It was crucial to improve the matter.
