1 lb (454g) Sn63Pb37 .40mm / .015" solder w/no clean flux , melting point : 183° C / 361.4° F
Kester 245 No-clean Cored Wire was developed to complement low residue liquid fluxes being used by the electronics industry. The chemistry is based on some of the same principles that have been safely used for years in mildly activated rosin fluxes. The use of 245 No-clean Cored Wire results in visually acceptable assemblies without cleaning, yet soldering quality and efficiency is comparable to that obtained with mildly activated rosin flux. Kester 245 was formerly classified as
Type LR per MIL-F-14256. Kester 245 is Bellcore GR-78 compliant

Performance Characteristics:
• Highly reliable post-soldering residue
• Minimal residue
• Compatible with leaded and lead-free alloys
• Classified as ROL0 per J-STD-004
• Compliant to Bellcore GR-78
