[Elecraft] Source of poor solder joints?

[Darwin, Keith]

Looks like poor soldering joints is the #1 problem with rigs we build.
While building my KSB2 I was wondering about and came up with an idea.
 
I wonder if many poor solder joints occur because of the lead moving as
the soldering tip is removed.  In the case of an IC, while I'm applying
heat, I'm pushing against the chip's lead.  When I remove the soldering
iron, the lead is going to spring back just a bit (i.e. move) as the
solder connection is cooling.  Could this be a major contributor to poor
solder joints?
