Aquanox A8830 – Low VOC Aqueous Stencil Cleaning Agent
Aquanox A8830 – Low VOC Aqueous Stencil Cleaning Agent

AQUANOX® A8830 is a mild formulation that does not damage stencils and is highly effective at removing all types of solder pastes (water soluble, rosin, and no-clean) from fine pitch apertures. AQUANOX A8830 is a low odor cleaner that can be used in open systems. The green environmental properties of AQUANOX A8830 make it an ideal option for areas where air emissions are highly regulated

Aquanox A8830 cleans solder paste from stencil apertures in ultrasonic immersion cleaning tanks, using a 10% solution at room temperature. The product does not phase separate and requires no mixing before or during use. Aquanox A8830 has virtually no odor with a VOC level of less than 1 gram per liter at use conditions. The product cleans all solder paste types including water soluble, rosin and no-clean. The product effectively cleans lead free no-clean solder pastes. Maximum wash cycle time is typically less than 4 minutes and Aquanox A8830 easily rinses with water, leaving no residue on stencil surfaces. Following the cleaning process, solder spheres fall to the bottom of the cleaning tank. The solder spheres may be removed using filtration or decant catch pans.


When processed in an ultrasonic powered stencil cleaning machine, Aquanox® A8830 also removes uncured SMT adhesives. In this scenario, Aquanox A8830 breaks up, lifts and disperses the SMT adhesive from the stencil aperture. When cleaning uncured SMT adhesives, a slightly longer wash time of 6-12 minutes is needed. When cleaning polypropylene pump stencils, the ultrasonic energy tends to be dampened by the plastic stencil. As such, a longer wash time may be necessary.

The active ingredients in Aquanox A8830 are not consumed during the solder paste cleaning process and very little chemistry is lost when running at ambient process temperatures. After the initial charge, no additional make-up chemistry is required until the wash bath is changed. For preventative maintenance purposes, a wash bath change out schedule of 1-2 months is recommended or in the case of heavy use, a one month change out is suggested.

Aquanox A8830 may also be used to clean pallets, oven radiators and other tooling. When using Aquanox A8830 for maintenance cleaning, heavy soils may require a wash temperature of 40-60°C at a concentration of 10-15%.
