Lead vs. Lead-free Solder

Heath
I started off using regular lead solder because that's what I had.  Later I switched to Lead-free solder on the suggestion of a musician friend of mine who got me into pedal building.  It took a bit of getting used to with regards to melting point, flow, and the tendency for good lead-free solder joints to appear dull, which is not a great sign when using lead solder.  It also smells pretty foul when melted and the vapors are toxic, if I recall.

On the other hand, lead is nasty stuff, poison-wise, and seems to really foul up my solder tips, whereas the lead-free stuff just take a quick wipe on a wet sponge and it's all nice and clean.  

Well, I finally used up my spool of lead-free solder and was going to order more.  I figured I'd get some opinions since I've been really impressed with the level of knowledge here.

Do most of you use lead or lead-free solder and what are you experiences in favor or against?

Leaded 60/40.  I really don't like every lead free solder I've used and my soldering style and timing seems to have been tuned entirely for 60/40 so it's difficult to take to something that affects the melting point.

Leaded 60/40 here too, find it easier to work with.

I use leaded 63/37, which cools faster than 60/40. I find that invaluable when soldering wires.

60%st/40%lead 1mm when working with veros and 60%st/38lead/2%copper 0'5mm when using pcb's.

Never have seen a lead free solder by the way.

I use lead free because i don't get a hedeck from it which I thought I got from soledering wire containing lead.

You only get flux fumes from leaded solder, the same as unleaded.  Lead doesn't vaporise until a much higher temperature than you get from a soldering iron.

Haha, yeah I think i just got some paranoia. Anyway as soon as i got just to the lead free i didn't want to change back.

I'm pretty much in the same boat as you Heath, I started off with a big spool of lead free which I was getting near to the end of, so I ordered a small amount of 60/40 roisin core solder.  I just finished my first build using it and I have to say I'm pretty happy, over all I used less solder per joint than I would with the lead free, they seem a bit neater and it took less time to solder the board, all in all a massive win.

The only thing that will be lead free in my workshop/man cave will be me by the summer!  Two kids is enough, haha!

Is it true that the aviation & transport industry had a 10 year dispensation from when the rohs directive came into force, due to lead free solder causing spike shorts?  Doesn't it crystallise is someway?  Or have I been fed a load of bovine faecal matter?
It's better to have it & not need it, than to need it & not have it!

with all the health issues brought up with the lead thing, I was thinking that "spike shorts" might have had something to do with a urinary tract problem. Turns out, I'm just a gross person.

All the lead free stuff I've tried seems to be pasty... couldn't get on with it at all.

Lead doesn't vaporize until past 800 degrees, so no lead worries from just soldering. I use 60/40 in a very small diametor for boards and .050 for offboard stuff. I also used 63/37 sometimes because I have some in an in between diameter, but I prefer 60/40 for the most part. I have used lead free and still have some but I really don't like it at all.
