I am doing some pcb repairs, and wondered what watt soldering iron works best. I have one that is selectable to either 15 watts or 30 watts. 30 watts heats things up real fast, and needs contact only 3-4 seconds to solder. On 15 watts, it is tamer, but requires heating up the componets for 7-8 seconds to solder. Is it better to have 30 watts of heat for a short time or 15 watts for a long time? I am worried the 30 watts of heat for even short times might damages the pcb. Any ideas? Also I use 63/37 solder. Is that really better on pcbs than 60/40?
thanks,
