Matching perspective

I have photographed an assembled electronic circuit board in a more-or -less isomtric perspective. Now I am being asked to "remove" a component, which would require adding features that are blocked by that component.

To add those featues I can photograph a bare circuit board (no components assembled) and try to copy the affected section onto the original picture (is this what is called compositing?).

Since I do not have fixed positions for the camera and circuit board when photographing, my biggest challenge will be matching the perspective of the two pictures. Are there any Photoshop tricks that can help me with that, or do I just need to play with perspective/skew until it looks ok??

Thanks.
