Available models

No Clean Flux

AIM’s no clean flux is designed to leave minimal, electrochemically safe post-process residues. AIM’s no clean flux provides fast wetting and increased PTH barrel fill while reducing common soldering defects including bridging and solder balls. AIM’s no clean flux activation system has a wide process window that can withstand high process temperatures.


Available Flux Products

  • FX16 No Clean Liquid Flux
  • NC275B No Clean Liquid Flux
  • NC280 Liquid Rework Flux
  • NC217 Lead-Free & Tin-Lead Gel Flux
  • NC Paste Flux
Water Soluble Flux

AIM’s water soluble flux products offer a wide process widow with superior wetting characteristics and easy to clean post process residues.


Key Features of WS715M Liquid Flux

  • Neutral PH Flux
  • Lead-Free and Tin-Lead Compatible
  • Excellent Wetting

Key Features of WS716 Liquid Flux

  • Halide-Free
  • Rosin-Free
  • Phosphate-Free

AIM’s rosin based liquid flux is designed for use in avionic and military type applications with non-corrosive residues that can easily be cleaned using a solvent or saponifier. AIM’s rosin based flux provides improved soldering performance, excellent thermal transfer and can be foamed, sprayed or dipped.
