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.

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.





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.



VOC-Free Flux

AIM’s VOC-free liquid flux products are environmentally friendly, water based fluxes with exceptional performance and reliability characteristics. AIM’s VOC-free line offers excellent barrel fill and wetting performance with a wide process window.



Paste Flux

AIM’s paste flux is available in no clean, water soluble, and rosin based chemistries. AIM’s paste flux is for use in rework applications, general touch up, rework of PCBs, BGA rework and ball sphere attachment applications.
