This show 3 components on a 3D model. The one to left is a 0603 package, and if you have any idea of how small that is then you also see the size of INA210 in the middle. INA194 is SO-23/5 which is “easy”. I consider 0603 easy as well, but 6 pins on that INA210 was a bit on the edge.
I have never tried a 0402 component and based on my experience with 0603 I don’t think I want to either – not with manual assembly.
