At the moment only diodes , but what about more sophisticated stuff?
Required a way of holding 2 of the tiniest (2mm long dimension) SMD
devices in registration , to solder together . Used a 6 pole rare earth
magnet from a VCR motor. Also broke a chip off to epoxy to the end of a
matchstick as a manipulator, for transfering to pcb and holding in place
while first solder dab.
Any devices a definite no-no for high local magnetism? , presumably some
SMD termination metal is not ferrous for one thing.

While at it, any problems with fine chip geometries in cameras, fancy
phones and computers, passing through airport X-ray scanners?
