## Questions & Answers

**Q: Is this ok for pcbs? normally i don't care about cosmetics, but if i make a board for someone else how can i clean it? ipa?**
A: I use it for cellphone PCB soldering..I have also used it on a prototype board..it has a low melting point 
It gives a good finish..& cleans easily..
You can use Mg chemicals 99.9% alcohol to clean..or ABRO contact cleaner..or WD40 contact cleaner..FLUX is also easily cleaned by warming the board up a little and then use the alcohol with a brush to clean..

**Q: I see different 63/37 kester types of solder.  what is diff. between rosin core (i know what this is), organic core, no-flux core?**
A: Just so you know "Water Soluble" flux is highly corrosive...  You might think it's safe as it's called organic/water soluble, but it will strip you tin within hours if you don't completely clean it.  This solder is an "RMA" solder or "Rosin Mildly Activated" it is a very safe flux that doesn't require post clean, though your surface to be solder must also be very clean as it doesn't have much in the way of cleaning action.

**Q: what is the melting temperature of this solder?**
A: * Melting Range: 361º F, 183º C

**Q: Is this solder multicore ?**
A: Multicore Solder is a different manufacture, this is Kester Solder, all the same
