Features of Tin Lead Free Solder Bar:

1. Eutectic alloy.

2. Bridge-free and icicle-free soldering.

3. Smooth, bright, well-formed fillets, free of gross micro-cracks, irrespective of the cooling rate.

4. Good through-hole penetration.

5. Good topside fillet formation.

6. Dross rate equal or lower than tin-lead solder.

7. Does not require a nitrogen atmosphere.

8. Does not erode copper from holes, pads and tracks.

9. Low rate of copper leaching makes it easy to control the copper content of the solder bath.

10. Lower aggressiveness to stainless steel and other solder pot materials as compared to tin-silver-copper alloys.

11. Thermal fatigue resistance and creep strength better than tin-lead.

12. Slow, even growth of the intermetallic layer at the solder/substrate interface.
