Has anyone some experience with diffusion paper ?
used while exposing ED resist in order to expose
the inside of the non-plated holes.
What types of paper exist, thicknesses, diffusion factors ?
Are some of the japaneses using ED technology willing
to share their experience ? Either avoiding diffusion papers
in using other exposure technics / machines !
Any suggestion welcome.
Regards
