'[EE] DIY Board Toner Removal?'
2005\03\31@220800 by Gordon Williams

Hi All,

Any ideas what solvent can be used to remove the toner on a board once it
has been etched?  I've tried acetone and white gas (naphtha camp fuel) and
those don't work well.

My first Brother printer had toner that could be easily removed with
acetone.  One wipe and it was gone.  With my new printer (another Brother)
the toner formula seems to have changed and acetone doesn't remove much.

I guess I could scrub it off, but then I would loose some copper as well.

Any ideas?

Regards,

Gordon Williams

Try some Lacquer Thinner...it is a concoction of some really nasty
solvents that disolve pretty much anything. It has worked in
situations where acetone, MEK and xylene failed to the job at hand.

Cheers,

I use 320 grit wet sandpaper. You loose very little copper, and the
benefit is you end up with a very clean and nicely rough surface that
solder seems to like. Takes me about 2 minutes to do a 4"x6" board.

Indeed, works well on samsung toner. Ten dollars will get you a gallon
'round here.

Its known as "Cellulose Thinners" here in the UK, if that helps the OP.

I now use rs-components' 216-2706.

Steel wool?

I once had a PCB that had been cleaned with steel wool before being
assembled and found that small steel "whiskers" had worked their way into
strange places, including underneath a connector. It was not fun to find all
the resulting short circuits. Ever since, I've been cautious about steel
wool and PCBs.

I use a household abrasive cleaner, such as Comet, with a sponge or a
Scotch-brite pad, to remove the unwanted toner. It is milder than sandpaper
and also yields a good surface finish.

I use something called "Citrusolv", only because it's what we have around.
I gather it's a common-ish solvent in biomedical labs, but past that I
can't say.

If I had to guess, I'd say it's pretty similar to most grocery-store available
citrus-based cleaners.  The toner runs off quite readily, and I have yet to
identify any undesirable side effects.  Plus, the room smells orangey-fresh!

aerosol brake part cleaner.  recycle with used oil or paint, or just
let it evaporate.  works like a charm on laser printer toner.

I went out and bought some lacquer thinner as someone suggested.  It worked
well.  The litre will last me the next 100 years.

On the other hand.. it would be great if there was some chemicals able
to "eat" paper while leaving the toner on the copper clad.

Anyone has some idea on some substance able to do this to paper, while
being inert on the toner and copper?

As a first thought, I had that too, but the toner won't survive I'm sure..

How about water and agitation.

Maybe a dilute chlorine solution.

you don't have the right paper.  try clay based paper, magazines use
it,  try some different magazines until you get the one that doesn't
leave any lint.  My success happened to be a Carvin guitar catalog.

But you then reuse it, or throw it off?

In the latter case, buying a magazine for each PCB may not be really
too convenient.
