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.
In wave solder operations, less solder is consumed in comparison to tin lead solder because the weight per cubic inch of the solder is lower. The lower viscosity improves the fluidity, which in turn improves the solder’s wetting capability and reduces necessary re-work including bridging, icicling, cobwebbing and flagging. This alloy is environmentally friendly, and generates less dross compared to all other “virgin grade” LF solders. Less dross generation results in more soldered joints per pound of solder and greater cost-effectiveness through less waste. This alloy exceeds specification J-STD-006.
SN100e contains cobalt. Competitor alloys contain nickel. 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.
Available In The Following Forms:
Qualitek has developed LF GREEN® to avoid cross contamination.
LF GREEN® is a patent pending lead free solder paste that is green in color and remains green during the entire soldering process until reflowed. Once reflowed, clear residues remain with normal metallic joint appearance. Under black light LF GREEN® boards will fluoresce once again easily identifying the lead free boards. LF GREEN® is available in the most common lead free alloy compositions of Sn/Ag/Cu and Sn/Ag and costs are the same as typical lead free solders because costs are based on the metals and not the green color of the paste. Formulations are available in No-Clean, Water-Soluble and RMA flux types. Available in type 3, 4 and 5 meshes. Packaged in DEK Proflow Cassettes, Jars and Cartridges.
