NC265 LIQUID FLUX FEATURES Broad Process Window Fast Wetting for Lead-Free Alloys Halide-Free Low Post Process Residues REACH Compliant DESCRIPTION NC265 is an alcohol-based no-clean liquid flux formulated to offer a very wide process window for lead-free and tin-lead wave soldering operations. NC265 promotes faster wetting than previously formulated fluxes for all lead-free alloys including SN100C. NC265 is compatible with a broad range of lead-free and tin-lead solder alloys. NC265 leaves low post-process residues and reduces preventative maintenance and cleaning on pallets fixtures and spray equipment. NC265 is designed to be a no-clean flux which can be cleaned if critical to the product application. CHARACTERISTICS HANDLING & STORAGE Parameter Time Temperature Wetting Sealed Shelf Life 1 year Room Temperature NC265 has a sealed shelf life of one (1) year when stored at room temperature. Do not store near fire or flame. Keep Low SIR away from sunlight as it may degrade product. NC265 is Residue Reliability shipped ready-to-use, no mixing necessary. Do not mix used and unused chemical in the same container. Reseal any opened containers. Storage conditions range from 4- 40 C (40 - 100F). APPLICATION Corrosion NC265 is formulated for application via spray, foam, brush, Hole Fill Resistance mist, or dip. NC265 is ready to use directly from its container, no thinning required. When spray fluxing, proper flux coverage and uniformity are imperative. A dry flux coating of 500-1500 micrograms per square inch is recommended as a starting point. Spread When nitrogen sealed wave solder equipment is used, it is generally necessary to apply additional flux. NC265 NC266-3 Document Rev NF3 Page 1 of 3 PROCESS GUIDELINES Using thermocouples attached to the top of the PCB, the topside CLEANING assembly temperature should be between 85-110C (185- NC265 can be cleaned using a saponifier or chemical cleaners. 230F). It is important that the flux be dry prior to entering the Deionized water is recommended for the final rinse. Contact wave regardless of temperature or spattering will occur. AIM for additional information. Smoking may occur and is considered normal if it is not excessive. Recommended contact time with the wave is SAFETY dependent on wave configuration, pot temperature, alloy type Use with adequate ventilation and proper personal protective and thermal mass of the assembly with 4-7 seconds being equipment.
