My current large-format pet project involves electronics, microcontrolers, sensors and various other gizmos. So i get to make my one pcb (printed circuit board).
Lets look at the requirements:
+ Epoxy + copper layer
+ Light sensitivive emulsion
+ Circuit layout laid over it
+ Expose to UV for some time...
+ Develop in some wierdo chemical
+ Wash, hang out to dry (almost)
Sound familiar ? Yes it does.
So my current pet project got sidetracked while I study how I could contact print a photograph on a copper plate. Anyone tried that before ? what kind of density/tones can I expect ? what sort of exposure time ?
What about protecting against corrosion ? Any laquer/varnish idea ?
Fun !
