Organic Acid Flux Residue Cleaning Chemistry – AQUANOX A4382
- Category: PCB Cleaning Agents & Chemistries
- Manufacturer: Kyzen
An advanced cleaning agent targeted at organic acid fluxes. De-Ionized water alone results in insufficient or inconsistent cleaning, however, A4382 completely removes all water-soluble residues and other possible manufacturing contaminates. AQUANOX A4382 effectively cleans underneath low standoff or flush mount components.
About the Organic Acid Flux Residue Cleaning Chemistry – AQUANOX A4382
AQUANOX A4382 is a near neutral range pH chemistry designed with superior cleaning efficacy with great material compatibility on surface mount assemblies. With smaller form factors (miniaturization) and high reflow processing conditions (lead-free soldering), water soluble flux residues may oxidize and char. When this occurs, highly active flux residues may no longer be easily soluble in hot DI water alone. A4382 most effectively cleans organic acid flux residues at lower concentrations. AQUANOX A4382 effectively cleans under highly dense surface mount components without reacting with exposed metals or damaging substrates.
A4382's intermolecular attractive forces for polar organic acid flux residues allow for rapid dissolution of the flux residue. The surfactant technology engineered into the cleaning agent lowers surface tension to allow the cleaning agent to penetrate the components' Z-axis. The low level of free alkalinity in combination with corrosion inhibition technology protects exposed metals from cleaning agent attack.
Oxidized organic acid flux residues generate an insoluble salt that A4382 dissolves. When comparing AQUANOX A4382 to other aqueous cleaning agents, this product performed exceptionally well. This is due to specifically selecting ingredients that match up to the residues left from organic acid fluxes.
AQUANOX A4382 is formulated as a concentrate. This product is designed to work in spray-in-air aqueous cleaning machines. The concentration needed is typically less than 10%. The product is low in odor and contains no hazardous materials. The product has a wide material compatibility window and is specifically designed for use on printed circuit board hardware.
The product is RoHs compliant and Halogen-free in accordance with RoHS Directive (EU) 2015/863 and EN 14582:2016
