[Blindtlk] soldering electronic parts

David,

I didn't have time to get into all that in my explanation involving placing the iron on the connection until the solder melts.  
However, what you describe is going to be true for blind or sighted persons doing the soldering.  Using a small clamp or 
clip works, and one can also buy special clips that are very narrow that are made specifically for this purpose.  Also, and 
this may be obvious, but it is the connection that I said should be heated and not the electronic part itself.  The heat 
sink is still required, though.  If one is soldering a 1/4-inch jack, it may not be necessary, but I always feel some kind of 
heat sink is a good precaution.
