Batch Stencil Cleaner
1572
Introduction
Designed for ultrasonic and spray-in-air sy ste ms, Eco-Stencil AQ batch stencil cleaner offer s great
cleaning performance with much lower environmental impact. Effectively removes all types of
solder paste (e.g. water-based, RMA, no-clean, lead-free) and uncured adhesives from stencils and
misprinted boards. Eco-Stencil AQ is improved to reduce foaming in high pressure stencil
equipments.
When a water rinse is a part of the cleaning process, Eco-Stencil AQ provides an economical, yet
powerful cleaning solution. This water-based cleaner uses the latest in environmentally friendly
surfactants to break down pastes and adhesives. Concentrated formula saves shipping and
storage cost.
Drop-in replacement for semi-aqueous and aqueous cleaners. Eco-Stencil AQ c an be used in all
the most popular cleaning equipment: Aqueous Technologies, Austin America Technologies,
SmartSonic, EMC Global, and more. Eco-Stencil AQ works with current filtration methods,
providing a long bath life and minimized disposal cost.
Eco-Stencil AQ batch stencil cleaner has been tested and proven compatible with every part of
your stencil — from the frame, screen and stencil to the adhesives binding it together.
