Homebrew PCBs

DuWayne:

Thanks for the detailed account of your heatless toner transfer experiment.

As I suspected, the need or exotic materials is not required.

There are many materials that will dissolve the polymer particles
that make up laser printer toner, and the alcohol mix-in is used primarily
to reduce the effectivity of the solvent so that it softens, but does not completely
distort and weaken the image too much.

Xylene is a good choice because it is relatively inexpensive
and readily available. Same for denatured alcohol, and I think
that ordinary drug store 70% or 90% isopropyl alcohol should
be OK.

The alcohol  is also effective in cleaning the bare PCB material.
I plan to try to duplicate your process sometime this week.

Thanks

Roland F. Harriston, PD
