Subject: Re: [Homebrew_PCBs] Re: cheap TRF foil experiment is a success

YES very wide.
MACK TRUCK highway lanes wide.
My vision is impaired.
so bigger is better for me....
nothing I do is ever going to be used in anything real world for sale...state of the art being
smaller is better.....SMT... etc... its just hobby stuff.
BUT
the experiment IS the same...laser print....  heat toner.. transfer to copper and  etch.

Noting that sometimes the toner transfered is not perfect...has very tiny pitting....
so
thie idea here is to cover all traces with this next layer...green stuff... pigment....
and then have less pitting damage to copper traces.

My solution to this pitting problem was to trace all toner with a
SHARPIE or EDDING 404 permanent marker
BUT
and this is the real reason for using TRF
WHEN IT GETS REAL SMALL I can't , you can't, expect to trace the real thin lines
and pads without screwing up the artwork too much so
TRY the green stuff
and see if it cures the normal pitting.

 TWO heats doesn't seem to be a problem.
I'm not mashing with rollers though.
So I don't get that extrusion factor.

Your traces are awfully wide.   I would like to see experiments with more narrow traces.

This stuff looks interesting for transfers for things like silk layers and labeling project boxes.

But from my reading it looks like you now have 2 transfers to worry about. One for the toner, one for the foil.    What is the advantage here other than some cool colors?
