A web cleaning system is a system to remove dust and particles from a moving web. There are two basic types of Web Cleaning Systems:
Many sectors, these days, demand zero defects and zero rework. The challenges of producing high quality-high volume electronics have never been tougher. Defects caused by particles cause significant yield loss. So the industry is moving from defect detection to defect elimination. The Contact Web Cleaning principle; An elastomer cleaning roller makes contact with the surface to be cleaned. This roller picks up the particles of contamination and captures them on an adhesive roll. Permanently removing the particles ensures fewer defects in subsequent processes. Simco-Ion cooperates with Ziegener & Frick.
Contact Web Cleaning Systems touch the moving web and can only be implemented when the cleaner does not damage the web during cleaning. Non-Contact Web Cleaning Systems do not touch the moving web and use air and static eliminators to remove particles and dust.
A Web cleaner system consists of a number of parts to make the complete system. Firstly there is a Web cleaner. This can be a non-contact web cleaner or a contact web cleaner. The other parts of a web cleaner system usually are suction-hoods or vacuum suction hoods to take away the particles that have been removed from the web. Webs can be contaminated on two sides and therefore sometimes consist of a system on both sides. This is depending on the thickness of the web and the kind of (accepted or not accepted) contamination. Next to these parts there usually is cabling and monitoring in place. Cabling to power the different anti-static bars and to make. In case of sucking of the particles a vacuuming system is needed. Also sometimes a fan or blower can be used to just blow-off the particles after the static electricity has been eliminated by the static eliminator. Contact web cleaner systems consist in basic of an elastomer cleaning roller that makes contact to the surface that needs to be cleaned. This roller picks up the particles and contamination on an adhesive roll.
For years Simco Ion produced many different non-contact web cleaning systems. Now we have a specialized partner for Cleaning solutions. Non-contact web cleaning systems are available in two different versions:
