025-NP Water-Soluble Rework Flux (10CC Syringe)
TACFlux 025-NP is the rework flux for Sn63/Pb37, Pb-free, and high lead-bearing alloys in an air or inert gas reflow atmosphere. TACFlux 025-NP provides excellent wetting in air or nitrogen atmospheres. The flux and flux residue is halogen-free per IEC61249-2-21.
Due to the discontinuance of the supply of a single raw material, TACFlux 025-NP was reformulated as a substitute for the previous TACFlux 025 by mixing new chemicals together, to give an equivalent chemistry and the same performance.

Cleaning
TACFlux 025-NP is designed for water-wash applications.
Reflow
Peak reflow temperature should be 370°C in an air or nitrogen atmosphere.
Storage
TACFlux 025-NP syringes and cartridges should be stored tip down at 0-30°C. If refrigerated, TACFlux 025-NP should be thawed for 4 hours at room temperature before use.
