True, But those who dont have much exp can easy burn the board an or get solder every where. So unless you have alittle bit of exp under our belt you can get by with "cold joint" I can tell you..first time I tried...I got a dap of solder an by the time I tried to get it off an this an that...i caused a good bit of damage.

Play with scrap..something you dont care if you kill it or keep it simple.
