I have never tried using this method, although I have quite a bit of
experience with lasers. Just off the top of my head, I see a problem. The
copper is not "even" on top of the clad. If you look at it with a magnifier,
you will see low spots and high spots. Even with varying feedrates you will
get burn marks in the substrate wherever there is a low spot in the copper.
I could be wrong about this as it is theory and not actual practice, but if
I am, could you please post a URL showing the project? I would also like to
see more on this.
