Trying to use the laser for etching a planar magnetic speaker (remove etch resists)

[WrineX]

Hi there

I revisited the laser etching method used by some for PCB's using it for aluminium laminated foil is a bit harder though 🙁

Part1 - Test ! piece

Part2 - Actual size test foil

Part3 - Reason why i am not going to use a foil like this for my current build
