Description: Superior OSP-2D is a dual-purpose coating/flux formulated to protect PTH and SMT PCBs from oxidation at the time of fabrication and as a spray-on flux for PTH/Wave Soldering applications. The flux, sprayed onto PCBs post fabrication, can be cured at temperatures up to 40ÂșC to leave a white coating on the PCB surface that provides oxide protection for bare copper and other PCB surfaces. PCBs can then be populated for single-pass protection in PTH or SMT applications. The coating acts to provide extra fluxing action during the soldering processes and yields a clear residue that does not need to be removed. The sprayed on OSP-2D is good for a single pass in PTH and SMT applications. Superior OSP-2D is also a No-Clean flux formulated for wave soldering applications. Superior OSP-2D meets all the requirements of Bellcore TR-NWT-000078, Issue 3, December, 1991; and all the requirements of IPC, ANSI, J-STD-004-Type REL0.Applications: Superior OSP-2D flux is formulated for all applications as supplied, and may be applied to parts in waterfall, dipping, or spraying processes. With extended use, the flux solids level increases causing the acid number to increase. Flux activity levels should be monitored and maintained using a titration kit. Add Superior No. 95T thinner to maintain proper acid number. Information provided by Superior Flux |
