No Clean Fluxes

Description

Description:

No-Clean Fluxes are a category of soldering chemicals formulated to leave minimal, non-corrosive, and electrically safe residues on the circuit board after the soldering process, eliminating the need for post-solder cleaning. These fluxes are crucial in modern electronics manufacturing as they improve process efficiency and reduce costs associated with cleaning agents, equipment, and wastewater treatment. They achieve their effectiveness through a low-solids formulation, often utilizing weak organic acids and activators in an alcohol or water-based solvent. By decomposing and volatilizing almost completely during soldering, the remaining residue poses no functional risk to the final electronic assembly, making them an environmentally friendly and time-saving choice for high-volume production.

Applications:
  • Wave Soldering: They are extensively used in wave soldering processes for through-hole components to prepare component leads and pads for bonding to the circuit board.
  • Selective Soldering: Their low-residue property is highly beneficial in selective soldering applications where cleaning may be difficult or impossible due to localized component placement.
  • Rework and Repair: They are also applied in rework and repair stations, often in a pen or spray form, to facilitate localized soldering without introducing residues that would necessitate further board cleaning.
