Both Zestron and Kyzen are global suppliers of engineered cleaning fluids for removing flux residues from electronic assemblies. Aqueous cleaning fluids are concentrated fluid compositions that rapidly dissolve, and in some cases saponify the flux residue. PCBA cleaning machines provide dynamic forces that allow the cleaning material to penetrate, dissolve the flux residue and remove from the surface and under low-standoff components.
Aqueous cleaning fluids are built with four driving forces: 1. Dissolution, 2. Saponification, 3. Wetting, 4. Minor ingredients to address foaming and compatibility. Aqueous cleaning has been more challenging as electronic assemblies move toward increasingly dense circuit designs, populated with low-standoff components, and the move toward Pb-free. To address these challenges, both Zestron and Kyzen works closely with customers, solder material companies, and cleaning equipment companies to design cleaning fluids that address customer needs.
