Clif,

I guess you're meaning that people might be apt to pull the toothpick
and break the solder.  I just read it as a way to prevent the "flea
speck" surfaced mount device from flying into who knows where!

I use a pair of non-conductive carbon fiber tweezers and a surface
mount solder station/vacuum unsoldering unit.  I look at the flea
specks with a Bausch & Lomb 7x eyeglass loupe.

Other tricks that I've used is taking some butcher paper and making a
mask so that if the part flies off (or I loose it with the tweezers)
it falls into the paper and I can "pour" it out by making a spout
shape with the butcher paper.  Smaller size white paper works for
small circuit boards too.
