[sdiy] unleaded solder

[Phillip Harbison]

Last night I was soldering for the first time in many years. I
am trying to use lead-free solder. I believe it is 99% tin and
1% copper. In the lead solder days I never had a problem with
getting good joints. Last night I had lots of problems. Perhaps
it is more a matter of declining vision and unsteady hands, but
I'm inclined to believe the solder is part of the problem. When
using lead solder it was quick work so my eyes and hands did
not have as much time to become fatigued. It seemed to take
forever to get the solder flowing. I had my iron set at 430•C.
I'm not sure if that is sufficient temperature, but it is near
the iron's maximum temperature. I struggled to assemble a kit
with a ZIF socket, a dozen discrete components, and a handful
of connectors on a 1.25" x 4" board. I did not time myself but
I'm guessing at least 90 minutes. Any suggestions on what I
might be doing wrong? Should I give up on lead-free solder? I
would appreciate any advice anyone can offer.
