For soldering we need to have the following handy
1) Soldering Iron
2) Soldering Wire
3) Soldering Paste
4) Soldering Stand
5) Tray
6) Desoldering Pump
7) the two points we want to solder
Heres a step-by-step walk through -
1) first of all, collect all the materials and place them orderly on the tray
2) now we power the solder iron and allow it to warm for 3-5 minutes
3) then, we dip the tip of the solder iron into the soldering paste and then we hold it tightly over the place or points we want to solder (not vertically but at an angle)
4) after sometimes we place the soldering wire slightly in contact with the soldering iron and wait for a few seconds for the wire to melt a bit
5) then the soldering wire is removed, and the soldering iron is also removed
6) if, for some reason the amount of soldering wire applied at the points is too much, we again use the soldering iron to melt the soldering wire at the points and use the desoldering pump to remove the extra soldering wire
7) after removing the soldering wire, we need to redo the htings from the beginning once again

none as of now..but if anyone requires one, i will be more than heppy to help :)
