pcb material with transparant substrate
pcb material with transparant substrate
(OP)
hi there,
this really isn't a circuit engineering question, but perhaps someone can give me a lead on how to look for a particular kind of copper board (if it exists).
i'm looking for a single-sided copper board that has a transparent substrate. what i need to do is to create a stencil behind which i'll place light sources. the issue is that the stencil has loops in it, so the idea is to use copper etching techniques to remove areas i want light to show through.
any ideas?

If the job were small you could use quartz, but that would be expensive and not more than about 2cm on a side (probably).

silk-screening could possibly work - i'll look into that. i'd still like to pursue the etching idea because i can envision a project which puts the lights behind the transparent side of the pcb (instead of the copper side).

Sounds like something more appropos with a Lightscribe inkjet or similar printer than can take flat substrates. You could use straight acrylic as the substrate

Remember the days when we used to lay out PCBs using film and tape?
