Bar Solder, SN63/PB37; 1-2/3 LB
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, 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.
