When the copper is coated on the surface, then it can be cut by
laser. The heat of the vapourized coating material helps cut the
copper if thin enough.
In the spec area it mentions something about "no outer layer copper".
I may mean that it is either coated copper or simpley the panels do
not have copper on them. The copper gets plated on at the same time
as the throuh-holes.
Honestly, I am just guessing as to the mahine's abilities at this
point. They are too vague in the specs, unless you are familiar with
the system. It could be anything.
