Qualitek Delta 285-25 Flux is a Rosin Mildly Activated (RMA) fluxes formulated to meet the requirements of high speed soldering processes with activities close to a fully activated rosin flux. The higher solids content retains activity longer and will remain stable throughout the soldering process. 285-25 contains a unique activator and solvent system that prevents the activator from separating during a prolonged period of foam or wave fluxing.
285-25 can be applied by wave, brush, dip, and foam methods. It exhibits superior foaming
characteristics with a uniform stable foam head, and is excellent for tinning stranded wire, component leads, and attaching lead frames to hybrid circuit assemblies.
