Plasma cleaner has the following roles: plasma surface activation/cleaning; plasma etching/activation; plasma de-gumming; plasma coating and plating (hydrophilic, hydrophobic); enhancement of bonding; plasma ashing and surface modification of large-scale production occasions, through its treatment, can improve the material surface wetting ability, so that a wide range of materials to be able to coating, plating and other operations to enhance adhesion, bonding. It also removes organic contaminants, oil or grease.
