• 1.6667 lb bar (Qty 1) Sn63/Pb37 bar solder
• Each batch of solder alloy used to manufacture Indium Corporation’s bar solder and chips is analyzed for metallic composition and impurities
• To eliminate the chance of contaminating Pb-free solder with Pb, ingots come in two shapes to designate the alloy
• All bar solder complies with the requirements of ASTM B-32, the most current J-STD-006 (formerly QQS-571F) and JIS-Z-3282

Indium Corporation manufactures bar solder specifically to surpass the strict quality demands of the surface mount industry in order to provide more consistent and reliable performance. Bar solder is available in a full range of SnPb and Pb-free alloys, including industry standard Sn63 and SAC305. To eliminate the chance of contaminating Pb-free solder with Pb, ingots come in two shapes to designate the alloy. All bar solder complies with the requirements of ASTM B-32, the most current J-STD-006 (formerly QQS-571F) and JIS-Z-3282.

Indium Corporation also features RoHS-compliant Sn995 Pb-free bar solder (99.5Sn, 0.5Cu + Co), which is manufactured from electrolytically processed tin, copper, and cobalt to create a solder so pure it far exceeds the most common specification requirements. The addition of cobalt forms shiny, uniform joints, and reduces the amount of dross generated during wave soldering. The melting point is approximately 228°C and recommended operating temperatures are between 260–270°C.

Quality and Process Control

Each batch of solder alloy used to manufacture Indium Corporation’s bar solder and chips is analyzed for metallic composition and impurities. Indium Corporation will certify its bar solder to meet customer specifications with a Certificate of Compliance or provide a Certificate of Analysis upon request.
