Oops, I retract my statement: the above would work for just the solder
dispenser. You're right, you'll probably need some sort of vacuum pump for
the pick-and-place machine. It can't be that difficult, though: the vacuum
needed to pick up one of those parts must be incredibly small. You could
probably even have the Z-axis stepper pull the plunger on a syringe to
create the vacuum to lift the part.
