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.
13. Also performs well in selective and dip soldering.
Applications of Lead Free Solder Bar
1. Dip soldering or Wave soldering of electronic components such as PCBA, THT
2. Soldering of metals, such as copper roofing joinery
3. Assembly of stained glass, silver jewelry etc
4. Other generally tinning purpose.
