Zestron has introduced the defluxing agent Vigon N 501 at this year’s Productronica trade show. Vigon N 501 is the first pH-neutral defluxing cleaning agent worldwide. Its ability to remove a wide range of flux residues from electronic assemblies under pH-neutral conditions is unprecedented. Due to its neutral pH-value, the cleaning agent demonstrates the highest level of compatibility on sensitive materials of SMT production, such as aluminium, copper, brass, nickel, plastics or labels. The water-based MPC (micro phase cleaner) was specifically developed for spray-in-air processes. Being used at short contact times and with bath concentration levels as low as 10 to 15%, Vigon N 501 shows very good cleaning results, even under low standoff components. Furthermore, the environmentally friendly pH-neutral formulation facilitates achieving the permission to dispose of the rinse water via the public sewage system. The cleaning performance was subject to extensive cleaning trials.
