Glass Screen Protector As PCB Substrate

[Max Headroom]

I notice that very thin glass sheets are available as screen protectors for smart phones.
These protectors have holes and cutouts to match phone front panels.
I would like to try these protector sheets as pcb substrate material with self adhesive copper tape as conductors.

Anybody have experience with these protectors, and tips on cutting to size and drilling holes ?.

Hard work, no benefit, I would just stick with tried and tested standard PCB material, one of the FR4 based ones....

On the contrary, what I envisage should be much quicker/easier than etching...copper tape and kapton tape for building some fairly simple prototypes.
Perhaps a diamond burr is useful for drilling holes in these very thin glass sheets ?.

I have done that in the past but not on glass, somewhere I have a collection of copper tape in a variety of widths that we used for a project. A very simple one with LEDs, anything more complex is going to be a bit of a pain...
Also will it handle the heat if you solder devices to it....

....Also will it handle the heat if you solder devices to it....

That remains to be discovered....with care it ought to be ok....maybe.
My aim here is electrically ideal substrate for custom copper tape/exacto knife prototype stages.
I have eBayed some such thin glass sheets, I will soonish see how it goes and report back.

One could also just go through OSH Park. 2-layer board, 3 copies: $5 per square inch. https://oshpark.com

Toner transfer is really not that much trouble either.

Plain FR4.... seems good enough for all other electronics up to a few GigHz
