out of chip package or down at the board contact?tnx

Where the main thermal mass is, point of soldering iron at the junction of
pin and trace. If, like me, you rarely do SMD soldering and cannot justify
obtaining solder paste or sub-millimetre solder. If you have some way of
rolling , roll down 1mm solder to thin strip and slice down with a razor for
short lengths of sub-mm.

For SMD de-soldering , on the cheap, on my tips files below
