Description
Indium Sn995 | Lead Free | Bar Solder | 25lbs Case
Indium Corporation features RoHS compliant Sn995 lead-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. All bar solder complies with the requirements of ASTMB-32, J-Std 006 (formerly QQS-571F) and JIS Z 3282.
Why Use Cobalt?
There are a number of Sn/Cu-doped alloys available in the industry today but, unlike cobalt, they all have shortcomings. The addition of nickel is popular, but nickel has a lower operating limit of 0.035%. Below that percentage, the benefits of nickel are lost. Cobalt has a lower operating limit of 0.003% and a much lower risk of dopant depletion. Bismuth is also commonly used as a dopant; however, numerous studies show that Bismuth content is related to fillet lifting. This is not a risk when using cobalt.
