- Eutectic alloy.
- Bridge-free and icicle-free soldering.
- Smooth, bright, well-formed fillets, free of gross micro-cracks, irrespective of the cooling rate.
- Good through-hole penetration.
- Good topside fillet formation.
- Dross rate equal or lower than tin-lead solder.
- Does not require a nitrogen atmosphere.
- Does not erode copper from holes, pads and tracks.
- Low rate of copper leaching makes it easy to control the copper content of the solder bath.
- Lower aggressiveness to stainless steel and other solder pot materials as compared to tin-silver-copper alloys.
- Thermal fatigue resistance and creep strength better than tin-lead.
- Slow, even growth of the intermetallic layer at the solder/substrate interface.
- Also performs well in selective and dip soldering.
