autiful square blocks from the stencil turn into a pool anyway, but
then the solder mask does its job and the pool separates out onto the pads
(except for TQFPs -- gotta use solder-wick afterwards on them) once the
tin melts too. So for SOICs/TQFPs you might as well just lay a bead down
across a whole row of pads. It works just as well as a tiny dab on each.
