Removing paper after toner transfer?
2004-07-20 by Thomas P. Gootee
-----------------------------------
Hi all.
The latest type of paper that I've been using for toner transfer (the
"Staples Picture Paper") is a little more difficult to remove from the
board than I'd like it to be. It seems especially difficult to remove from
the 0.02" square drill-hole marks that I make on my patterns.
I am wondering if anyone ever found a relatively easy way to remove the
paper residue from small drill-hole marks.
I realize that some papers are much easier to remove than others. But I
like the Staples Picture Paper's other qualities so much that I would
probably rather deal with the hole-residue-removal problem than switch to a
paper that is easier to remove but isn't as good in other ways. Of course,
if there is a paper that is much easier to remove that is at least as good
as the Staples paper in the other ways, then I'm all ears!
The Staples paper is the only one that I've found that prints with
perfectly-even blacks, even in very large black areas, i.e. with absolutely
*NO* pinholes whatsoever, ever (using my HP LJ 4 and HP-brand toner). I
also get superb strength in the toner's adhesion to the copper, although I
don't know how much that's affected by the use of this paper.
So far, I've just usually used a stiff toothbrush, moving in tight circular
motions, to get the paper residue out of the drill-hole areas.
I could try a stiffer, larger brush. But I'm afraid that it might tend to
damage the tracks. (I will try it, though, and report back.)
I've also tried running the boards through the dishwasher, with and without
the soap, when all of the paper had already been removed, except for the
holes' residue. Not much luck, there, even though I positioned the boards
so the pattern would take the full force of the water from several of the
water nozzles at close range. (However, it WAS on the TOP rack... Maybe I
should try the bottom rack.)
Or, perhap someone knows of a solvent that will dissolve paper/clay/etc but
not the plastic toner (and not the FR4). That seems like it might help, if
there is such a thing. If no one here knows of anything like that, I'll
post the question to some of the sci.chemistry types of newsgroups and
report back.
