NC PASTE FLUX FEATURES Halogen/Halide-Free Low Voiding Wide Process Window Tin-Lead and Lead-Free Compatible Suitable for BGA Rework and Ball Sphere Attach Complies with IPC 7711-7721 Standard DESCRIPTION NC Paste Flux is a no clean tacky/rework flux designed for general touch up or rework of printed circuit boards, and for BGA rework HANDLING & STORAGE and sphere attachment. NC Paste Flux can be used for hand Parameter Time Temperature soldering, hot-air rework stations, convection reflow, or vapor Sealed Refrigerated 1 Year 0C-12C (32F- phase soldering. Soldering residues do not require cleaning and are Shelf Life 55F) clear and inert. NC Paste Flux is compatible with all tin-lead and Sealed Unrefrigerated 6 < 25C (< 77F) lead-free alloys. NC Paste Flux can be dispensed, brushed or stencil Shelf Life Months printed. NC Paste Flux complies with the IPC 7711-7721 standard. NC Paste Flux has a sealed shelf life of one (1) year when stored 0C-12C (32F-55F). Do not store near fire or flame. CHARACTERISTICS Keep away from sunlight as it may degrade product. NC Paste Flux is shipped ready-to-use, no mixing necessary. Do not mix used and unused chemicals in the same container. Reseal Wetting any opened containers. After opening, paste flux shelf life is environment and application dependent. APPLICATION Low Residue SIR Reliability NC Paste Flux is ready to use directly from its container, no thinning required. NC Paste flux is typically dispensed, swabbed or brushed onto the workpiece. PROCESS GUIDELINES Corrosion NC paste flux should be processed according to the alloy and Hole Fill Resistance application requirements. For application support, please contact AIM by visiting CLEANING SAFETY NC Paste Flux can be cleaned using commercially available flux Use with adequate ventilation and proper personal protective removers. Contact AIM for additional information. equipment. Refer to the accompanying Safety Data Sheet for any specific emergency information. Do not dispose of any hazardous materials in non-approved containers.
