Hi everybody.
I want use laser to burn the thin film black lacquer that covered on copper foil. maybe someone know what I want to do --- to etch PCB. simply say, make the lacquer gasify, and expose the copper so that the hydrochloric acid can only etching the exposed copper.
maybe the black lacquer is not a good choice..
the color of laser, red or green, even the UV?
but I don't know how much power of laser modules I shuold use. anybody has similar experience or advice(suggest)?
sorry for my bad english.
Thanks any replys..
