S-250/FRO is universally suitable for wave soldering. It is used successfully for a wide range of systems and wave types in both leaded and lead-free processes. Its high temperature stability and very good activity over a wide temperature range ensures a wide processing window with best soldering results. The surfaces are very clean after soldering, the SIR is above the standards.
S-250/FRO is unsuitable for foam and spray fluxing and not recommended for selective and manual soldering (see also product matrix).
Practice has shown, that no washing is needed for PCBA properly soldered with S-250/FRO. The IC test with needle adapters is generally not affected.
