Robotic Solder Wire; 230-RC Flux Core, SN63 Alloy (0.020 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 soldered
Apply the solder wire to the joint, not to the soldering iron tip
Use the lowest temperature possible
610–700°F (320–370°C) for SnPb and Pb-free
Surface mount (SMT) soldering should be completed in 1–2 seconds
Plated through-hole (PTH) soldering should be completed in 1–3 seconds
The robotic soldering process set-up is highly customizable and depends on the assembly being soldered
A 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 outcome
During 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
