Indium BAROT-06466 - 63/37 Leaded Bar Solder Sn63Pb37 Wave Soldering 25lb Box
Indium BAROT-06466 - 63/37 Leaded Bar Solder Sn63Pb37 Wave Soldering 25lb Box
The Indium Corporation BAROT-06466 is a eutectic Sn63Pb37 (63% tin, 37% lead) bar solder for wave, fountain, and dip soldering in electronics manufacturing. As a true eutectic alloy, it melts and solidifies at a single temperature (183°C) with no plastic phase — delivering consistent, bright solder joints, fast solidification, and reliable through-hole fill. Manufactured with conflict-free Grade A tin and very low oxide content, meeting ASTM B32, IPC J-STD-006, and JIS Z 3282.
Sold in 25 lb boxes only (15 trapezoidal bars per box).

Frequently Asked Questions
Why is 63/37 the preferred alloy for wave soldering?
Sn63Pb37 is a true eutectic alloy — it transitions directly from solid to liquid at 183°C with no plastic (mushy) phase. This means faster solidification, brighter joints, reduced tombstoning risk, and more consistent results at production speeds compared to near-eutectic alloys like 60/40.
Can this be used in fountain or selective soldering systems?
Yes — BAROT-06466 is suitable for wave, fountain, and dip soldering applications. The trapezoidal bar shape is optimized for easy loading into solder pots and efficient melting.
Is leaded solder still permitted under RoHS?
Yes, for certain applications. Leaded solder remains RoHS-exempt for high-reliability electronics (military, aerospace, medical), repair and maintenance of existing leaded assemblies, and other applications where lead-free alternatives are not suitable.
Why does oxide content matter in bar solder?
Low oxide content means less dross formation in the solder pot, cleaner joints, and less waste. Indium Corporation’s manufacturing process maintains very low oxide levels, reducing pot maintenance frequency and improving joint quality consistency.
