If you have a diffuse light source, let's say 8dp, directly above the component and the component is also 8dp above the background, then it'll look right for one component.

To account for the lack of parallex effect in the shadow when there are multiple components, you will then need a telephoto lens zoomed through the light source from a huge distance. I think we'll need a ring light.

Not with a "flat piece of paper of zero height"
