I feel a lot safer cutting any material with a bandsaw rather than
a jigsaw, especially small pieces of PCB. For the reasons you
mention plus a bandsaw is floor- or bench-mounted and doesn't
move, so is steady and stable. The downward travel of the blade
pushes the work firmly against the table (always use a piece of
scrap wood under thin materials). The other advantage is that a
bandsaw has a much longer blade (~ 2000mm) and that takes a
very long time to dull compared to the repetitive cutting with a
small length (~25mm) of a jigsaw or scrollsaw. The blade on my
scrollsaw does not last long with FR4 board, so I hardly ever use
it for that. And jigsaws and scrollsaws are too prone to chattering
and vibration, which gets very tiring on the fingers, that can go
quite numb
