AQUANOX A4638 is an engineered cleaning solution designed to remove flux residue from flip-chip and low clearance components on electronic assemblies and advanced packages. Due to low surface tension, AQUANOX A4638 removes water-soluble polar flux residues from highly dense assemblies at low concentrations.

AQUANOX A4638 was designed with specifically selected ingredients that match up to the residues left from organic acid fluxes providing excellent results in short process time. A4638 is compatible with all materials commonly used in electronic assembly manufacturing and cleaning processes.
