Temat: lead free solder alloy from Qualitek

This unique patented alloy has been developed as a lead free alternative for those now using costly SAC alloys and for those switching from lead containing Sn63/Pb37 alloys to the lead free process.

SN100e is manufactured
from tin, copper, and cobalt to create solder so pure it far exceeds the most common specification requirements. The lead-free solder alloy is RoHS compliant and reduces copper dissolution. This alloy provides brighter, shinier, less grainy solder joints when compared to other lead free alloys such as SAC305 and is much less expensive.

SN100e contains 0% nickel and upto 0.05% cobalt. Other known alloys contain nickel and 0% cobalt. The ratio of nickel commonly used in comparison to cobalt requires more frequent monitoring due to the increased depletion of the nickel in comparison to cobalt during process resulting in an increased cost for those using the nickel containing alternative alloys.
