I'm looking for laser cutting / engraving machine for cutting flexible aluminium foil laminate. Laminate would have 10um aluminium foil on top of 50um PET film. I would need to make flexible PCB.
I wonder if laser can do the job. I believe 20W fiber laser can cut aluminium, but I'm not sure, if it would cut through the PET film as well.
CO2 laser probably do nothing for the aluminium.
I wonder if someone has tested aluminium foil with 15W mini laser engraver?

450-455nm laser should burn aluminium?
