## Questions & Answers

**Q: How many feet or centimeters are on a spool, please?**
A: No idea I never Measure it.

**Q: Will this bond to aluminum lithium battery tabs?**
A: It is ok to use this lead-free solder wire for your product,

**Q: Is this lead free solder as good as lead solder?**
A: Dear Customer,

Thank you inquiry our Lead Free Solder Wire for electrical soldering,

I think the Lead free solder is better than Lead Solder wire, because it is good for environmental,

The melting temperature for Lead-free solder is a little higher than the Leaded solder, but I think it is not a problem for soldering, 
The flowability of lead solder is a little better, but it is not a case if you are good in soldering, 

All factory were using Lead Free solder for many years, 

I hope my answer helpful for you,

Regards,
