Subject: photoresist sensibility chart ref UV wavelength - PCB LDI using a PS3 diode

From: "dandumit" <dandumit@...>

Hi,

Does anybody has access to the sensibility chart related to wavelength
of exposing light source ?
I would like to know if a KES-400AAA PS3 laser module
(http://www.fineartradiography.com/hobbies/lasers/blu-ray/) would be
usable to directly expose the photoresist from a pcb.
This laser diode has a wavelength of 405nm (it's not uv is near uv)
but maybe it would impress the resist from pcb at an acceptable
exposure time.

Any comments are greatly appreciated.

Daniel
