Re: Questionable Toner Transfer Results

2005-01-06 by Stephen Bartlett

Many thanks to everyone who responded.

As I cleaned the board, I had no beading of water when done; it sheeted
off like it was oil-free.  The board as I received it seemed to have a
waxy coating, reminiscent of dried cosmolene.  I think I got all that
off.

I will use lacquer thinner or acetone outdoors, with suitable skin and
lung protection.

I will visit a few local copy centers this afternoon and see what I can
find in the way of laser copiers that will apply a more apparently heavy
layer of toner than I got originally.

Re: Gary's question, "Are u waiting till the toner dries again
              and board cools before removing the paper??"

Neither the paper of the toner ever "stuck" to the board, although I did
manage to apply a visible image over about 80% of the traces.

So,

	Try a different copier(s)

	Use lacquer thinner or acetone, not lighter fluid.

Thanks,

Steve Bartlett
