I just started learning how to solder, and I figured that it'd be easier to start using lead-free from the beginning, than to get spoiled by using the 60/40 and having to switch. I am willing to use leaded solder, but only as a very last resort.
I have a 30W pencil which I'm using. Everything I've read about soldering tells me it shouldn't take more than a few seconds. However, when doing practice joints (resistor onto solder strip, for example), I have to heat it for quite a long time before the solder melts. It often takes a minute or more, and if that trend continues it seems like it'd be murder once I get to solid-state components!
I bought some bare alligator clips to use as heatsinks, and tried them out soldering a 1N4001 diode (since I have plenty). They seemed to work well, since the diode itself wasn't hot when I finished, but it still took a long time.
My thinking is that the pencil might not have enough power to heat the joint quickly, since lead-free has a higher melting temperature. Should I try with a higher-wattage pencil? Radio Shack has a 40W for 8 bucks -- would that be sufficient?
By the way, the joints I have made are mechanically strong and electrically good, as far as I've been able to test them.
I'd appreciate anyone who has experience with lead-free soldering for hobbyists giving me some pointers. Thanks in advance!
