Mechanism of oxide film removal by KF-AlF3 and CsF-AlF3 mixed fluxes on Cu and Al base metals and their effect on wettability

open access: yesJournal of Advanced Joining Processes, 2022
CsF-AlF3 was added in different mass percentages to KF-AlF3 flux, and CsF-AlF3/KF-AlF3 mixed fluxes with different components were prepared by ball milling. The melting curves of four kinds of fluxes were measured using differential scanning calorimetry (
