The AIM Solder 15035 SAC305 FastCore Rosin Flux Solder Wire is a resin-based flux-cored solder wire that is designed to offer excellent wetting characteristics, bright and shiny solder joints, and lead-free compatibility. This product is very active and is recommended for fast cycle time soldering. The FastCore flux promotes good thermal transfer, offering excellent solder penetration into plated through holes or surface-mount interconnections. FastCore produces low-to-medium, clear post-process residues.
AIM SAC305 is a lead-free alloy that contains 96.5% tin, 3% silver, and 0.5% copper. This alloy falls under the JEIDA recommendation for lead-free soldering. It may be used with most existing equipment, processes, coatings, and flux chemistries.
