Indium 54505-0454 230-RC core, SAC305 alloy0.032 diameter, 1LB spoolMeets the requirement of J-STD-004B Type REL1The low-spatter formation gives you cleaner boards and increased operator safety with less than 1% spatteringLight-colored residue Robotic Solder Wire, 230-RC Flux Core, SAC305 Alloy (0.032 Diameter, 1LB Spool) Indium Corporation's CORE 230-RC is a formula developed to meet the demanding requirements of robotic and laser soldering. It incorporates a highly effective activator package with new “no-spatter” technology in high-reliability flux media. CORE 230-RC is fully REACH-compliant, containing no REACH substance of very high concern (SVHCs). CORE 230-RC is not used solely for robotic and laser soldering since it also performs exceptionally well in hand soldering applications. The no-spatter feature eliminates flux spatters that can burn operators' hands.Process Recommendations: Match the tip size to the part to be solderedApply the solder wire to the joint, not to the soldering iron tipUse the lowest temperature possible610–700°F (320–370°C) for SnPb and Pb-freeSurface mount (SMT) soldering should be completed in 1–2 secondsPlated through-hole (PTH) soldering should be completed in 1–3 secondsThe robotic soldering process set-up is highly customizable and depends on the assembly being solderedA smooth solder joint appearance requires the correct amount of temperature and time; fine-tuning the process parameters may be required to achieve the best possible outcomeDuring robotic soldering, flux build-up and charring may occur; to avoid build-up, increase the iron tip cleaning frequency or reduce the iron tip temperature ? Cored Wire for Robotic and Laser Soldering Indium Corporation specializes in making fine-diameter wire, typically between 0.008' (0.2mm) and 0.015' (0.381mm) diameter for robotic and laser soldering.
