AQUANOX A4625B was developed specifically to remove all types of solder pastes and flux residues from printed circuit board assemblies, including the latest lead-free solder paste formulas. Originally designed to address the challenges of batch cleaning systems, A4625B is also very effective when used in in-line washers.

AQUANOX A4625B is a low VOC, environmentally friendly product that has excellent material compatibility due to KYZEN’s revolutionary inhibition technology.  A4625B provides brilliant mirrored solder finishes even after multiple cleaning cycles. AQUANOX A4625B is utilized at low concentrations and temperature, which results in low cost of ownership.
