Homebrew PCBs

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.
