[sdiy] blue copper-clad circuit boards?

[Ken Stone]

Serge used to use a blue PCB material too. The photo linked below is the
component side of one such PCB. Blue material seems to be very much a '70s
thing, as were beige colored ones. Fiberglass became popular after that.

Not all copper clad boards are meant to be used for PCB fabrication either.
We had a batch done in chocolate once (that is just what the etcher used -
we didn't ask for it) and that material was designed for etched pictures.
Stick a solering iron near it and the traces fell off.
