Re: Post-Etch Topside Layout Labeling?

Stefan,

Thanks again. Man, you take a damn good picture! That transfer looks 
about a hundred times better than mine did too. On my double-sided 
boards, I'm supposedly dealing with 1oz of copper per side. The 
transitions look more troublesome than yours. The material is the less 
translucent greenish-brown colored stuff too, if that had any affect.

The Staples unit was supposed to have been the same one Pulsar bundles 
for PCB transfers (you probably already knew). I don't know if it has 
any rubber in it either. I've got a couple long rubber rollers here, 
one of which I've mounted by it's axles to a square aluminum bar via 
standoffs. That one was from a big Xerox machine. I use it with a drum 
finishing thing I made (manual feed between two sets of rollers). I 
know nothing about printer/laminator guts, but depending on where and 
how the heat source factors into that, I wonder if that idea would be 
half as functional as it is fun to think about.

I also wonder if the "wipe the back of the paper down with acetone-
soaked cotton balls" method would work for that. I've always imagined 
that process blurring the prints, but it would have the same "squish" 
you describe with the rubber.
