I am also trying for the first time, how do you do the transfer to the
slight etched copper board?

I use a different approach, I clean the copper with something like Dutch
cleaner then I put the board in the acid etchant and the copper will turn
darker, just a few seconds to maybe 15 seconds. I remove the board rinse it
off and then do the transfer. The toner sticks so good that if I use shinny
photo paper all I need to do is just peel off the paper and the toner will
stay on the board. Since I started to do this I have never had a failure. So
a short pre etch makes all the difference in the world for me.

I tried it a different way - I took pages from a Hot Rod magazine I have
(slightly glossier than the pages I was using from my other mag).  I then
printed off the two boards I'm trying to transfer onto regular paper, then
put those in my Minolta copier (which has original Minolta toner) and then
copied to the magazine paper.


 


I did about 5 minutes of solid ironing on each.  I did not however try
freezing the paper (my method was to just scrub it with a plastic scrub
brush under water - seems to work fine.  And again, it's always the same.. I
get about 80% including really, really fine details but there's always just
a bit missing in one area or another.


 


Does that toner transfer paper make any difference?  I mean, I've seen this
method work with magazine pages pretty quickly in youtube videos, however
the PCBs people do tend to be quite small.  Mine are bigger than the iron
surface.


 


I'll scrub the board down again and try one more time with freezing..  I
just hate that I can't see or tell if the toner has adhered properly before
I start peeling away.

My own take on that is remanufactured toner is probably different. It may
melt at higher or low temperatures than the real deal.


The only way you can know is to try it, and if it works, hope that the next
cartridge works just the same. There is probably more consistency with the
manufacturers toner.


 


As I suggested in my previous. Forget using the acetone.

Thanks muchly and one other question if I may.. does it make any difference
using original vs reman/compatible toner?  I have compatible right now.  The
only thing I have with original toner is my big Minolta copier.


Also just a clarification.. if I use Comet and then acetone won't that leave
me in the same place with respect to oils?
