What (metric) size have you managed to hand-solder ?

When it comes to electronics solder/repair, there's a very good reason why we have pick and place machines, and ovens to effectively bake our hardware. However if you're in a pinch and don't have this kit available, you're often forced to do it yourself by hand, frankly the sizes of some of this kit require a microscope!

 

Still, what is the smallest size (in metric) that you've managed to solder yourself by hand?

  • Size comparison left-to-right of Imperial 0805, 0603 and 0402 resistors respectively, compared to stripboard.

    0805 and 0603 can be straddled between tracks if prototyping on stripboard.

    0402 however falls through the holes : )

    (Edit: 0603 falls through the holes too but nevertheless is substantially larger than 0402 and so it's easier to handle).

    My fave tweezer for SMD is the middle one, it has squared off ends, and it's rare for a component to go pinging in the air. The pointy ones on the left carry that risk. The tweezer on the right is sometimes useful too, can get great positioning of parts with it, although when prototyping it's not necessary for it to look absolutely spot-on : )

    I think the middle tweezer is not manufactured any more, but I can measure the dimensions if anyone wants the info. (EDIT: I think Wiha 32325Wiha 32325 looks very similar. The one in the photo is 'VOMM PSF SA ESD').
