AIM's VOC-Free Flux Passes New SIR Requirements
Flux is available in many formats.
Cranston, RI — AIM's NC275LR VOC-free flux has passed the new SIR requirements. The company describes the flux as leading-edge technology for VOC-free fluxes. The flux eliminates volatile organic compounds and meets the newest SIR and corrosion testing requirements. Assemblers now can reportedly have a high degree of confidence in an environmentally-friendly product that yields the highest electrical resistance.

NC275LR is a water-based, halide-free, no-clean liquid flux formulated to offer low residue and excellent wetting for lead-free and tin-lead wave soldering applications. The new liquid flux passes the new SIR requirements under the IPC J-STD-004B test method at process temperature and when air dried.

The flux offers extremely low post-process residues resulting in better esthetics as well as improved first pass in-circuit testing and a reduced need to clean pallets and conveyors. NC275LR also has proven to reduce preventive maintenance requirements for spray fluxing applications.

Offering a broad activation range, NC275LR has proven to be an excellent flux for a variety of process parameters and applications, including lead-free wave soldering with tin-silver-copper, tin-silver, tin-copper and other alloys. The flux provides excellent performance even in extended dwell times. In addition, it offers low-fuming and fast solvent evaporation. The flux is compatible with a broad range of tin-lead and lead-free alloys and is available in a variety of packaging.
