Thanks guys.  Yeah, I’m kind of suspicious
about my toner here.  I’ve noticed before that, say,
original HP toner tends to have a more ‘shiny’
appearance than the ‘compatible’ stuff does.  I assumed
there was something different there.  I’m getting probably 75%
transferred after 10 minutes.. and it’s got great adhesion
once it does and is nice and crisp – but I just can’t
seem to get all of it.  I’m wondering if my magazine
(Macleans) pages aren’t up to snuff.  Or my
iron.  Brad  From: Homebrew_PCBs@yahoogroups.com

attempt at toner transfer    The acetone or alcohol should
not add any oil or other unwanted organic material to the
board. As long as all of the cleaner is removed from the
board I'm not sure there is any benefit of using acetone
other than helping remove traces of water quicker.

You should clean the board
shortly before you use it. If it sits around or a day or
maybe less depending on the environment it will pick up a
film of organic material and will also tend to oxidize.

As to toner, you may need to
experiment. Most people say that Brother brand printers do
not work because toner has a higher melting point. The
general consensus is that toner from the original
manufacturer tends to work well. Replacement cartridges from
other sources may or may not work well. The claim is some
suppliers use less plastic in their toner mix (the plastic
is what gets melted and binds and fuses the toner to the
paper). If true, it is probably not the cost of the plastic
as a raw material which is so expensive but the cost of
producing it in the small particle size required. What makes
up the rest of the volume when less plastic is used I have
no idea, possibly more pigment or some other filler with a
small particle size.

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.

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.

So I took a run at it.  I printed my artwork to magazine pages, then placed on my copper and ironed away.  The first attempt failed pretty hard
… 5 minutes with the iron and maybe 40% of it was missing.  I cleaned the board with acetone, printed again and this time went to 10 minutes.  Better.. but still missing bits. 
 
Wondering where to look for problems here?  Paper?  Iron not hot enough?  How do you know?
 
Also.. is there a limit to how many times you can attempt ironing on a PCB?

Brad,

The Denatured Alcohol they sell in the hardware or home improvement stores for thinning shellac should do the job.  It is a mixture of ethyl and methyl alcohols, and some other stuff that makes you very sick if you drink it.

I had little success with the mixture of alcohol and acetone. I tried several ratios, with poor results.  I tried pure acetone, and got a very good transfer. The only problem was poor control.  It was hard to tell when to stop the acetone soak before it toner ran all over the place. When I get a chance, I will try some ratios with high acetone.

I would like to try the cold method but have not had any luck, anywhere, finding ethyl alcohol.  Only isopropyl. 

 

I suspect toner is definitely a problem here.  I’m using ‘compatible’ cartridges, so that only seems logical.

Almost all the problems I had with using the toner transfer method with a laminator was because of the toner.
With the original toner from two different printer brands worked well, but replacement toner cartridges did not work very well or not at all.  One thing I found that helped was to run the blank board through several times to get it heated before I applied the  paper with the image to be transferred.  Once I switched to the cold method, I have  not had a problem using any type of toner.

I didn't even think you could buy it.

Been lurking for a while.

Anyway, I attended a informal discussion of a new fandangled method of, technically I guess, toner transfer. Utilizing Knox brand gelatine. Like Jello, but no flava. Let me see if I can remember the procedure.

Whatever the recipe is for plain gelative, use 3x as much water. IIRC one packet requires dissolving in 1/4 cup of cold water, with 1 3/4 cups of boiling subsequently added. So therefore to 1 packet add 3/4 cup cold water, dissolve, then 5 1/4 cups of water, for a total of 6 cups. Now that's a lot of gelatine, so you may want to "cut" the packet into portions w/a razor like a coca cola dealer :). Use your discretion. Just don't snort the stuff.

 Um while still a liquid (presumably it'll stay a liquid, too thin to gel but what do I know), paint with a cheap paint brush on to sheet/s of printer paper. Maybe let it cool a bit before painting? Let dry. When dry, print your artwork onto these sheets (on the Knox side obviously) using a copy machine (I don't remember inkjet printers being acceptable). Then you would iron those sheets onto copper board (using a cloth between iron and sheet), with steam IIRC. I think you could also bake it in the oven for a while to harden it, can't remember the details, maybe 100 degrees for an hour? Most ovens don't go down that low, so improvise I guess.

 I haven't tried it yet, but was told it's basically fool proof. Unlike the standard commercial toner transfer sheets which is so error prone to make it unacceptable. Give it a shot, let the group know. Any questions, feel free to ask, I'll do what I can to answer them.

>My problem isn't getting the toner to transfer well, it's etching. Lots of pinholes. The toner is too porous. I've tried the lighter fluid method of fixing the toner but no workie. The foil method will probably work if I can get the stuff hot enough to transfer. I am using original HP toner. Any thoughts ?

>Anyway, for sport, I went back to the process I had tried before. My PCB patterns are bigger than what’s out there on youtube, and I had been printing them on separate pieces of paper.

My problem isn't getting the toner to transfer well, it's etching. Lots of pinholes. The toner is too porous. I've tried the lighter fluid method of fixing the toner but no workie. The foil method will probably work if I can get the stuff hot enough to transfer. I am using original HP toner. Any thoughts ?

Well, I tried the cold transfer method and… yeah.. no dice at all.  Probably my mixture wasnâ’t working right.

 

Anyway, for sport, I went back to the process I had tried before.  My PCB patterns are bigger than what’s out there on youtube, and I had been printing them on separate pieces of paper.  This time, I printed them together on one piece of magazine paper from Hotrod Magazine (love that magazine).  Then I cleaned the board, let the iron get hotter than the blue blazes of h—ll.. and then went for it.  Spent a good 10 minutes really working the iron – first back and forth nice andd slow like a laminator, then faster, on the theory it would keep the paper hot all the way around.  I looked really closely and could kind of see where the toner was coming off the paper a little bit, and really worked the front end of the iron down on spots I thought were suspect.  Then I dunked the whole thing in a tub of cold water and let it sit for 2 minutes.  Anyway, voila!  The result:

Here’s a weird one.  You guys saw my successful
transfer image – with two of the four boards required to
build a TV Typewriter shown.  Those print perfectly onto
magazine paper via my Laserjet 4250.  But for some reason,
the motherboard won’t.  The motherboard is twice the size
of the other boards and it has relatively large black traces
that span long distances.  For reasons I can’t figure
out, when I print it to the magazine paper, it comes out
with some traces faded.. ie. not enough toner.  Usually
around the same spot.  Yet if I print it with regular
paper.. it’s fine.  Not sure what the remedy would be
here but I’m open to suggestions.  Not being able to
print the mainboard is a bit of a problem.  Brad

No.. they print dark.  I’m not
sure if it’s some kind of weird illusion with the magazine
paper.  I’m going to try an ironing with one later and
see what actually transpires.  I have another question – I did
another transfer of some of the smaller boards I needed –
and it looks great except just a couple of tiny spots. 
Looking at pictures of the original boards from SWTPC, it
looked like they solved these issues by simply bridging
solder.  But I’m wondering if there’s another way.. is
there anything equivalent to ‘touch up paint’ I could
apply to spots where the traces are or risk being broken to
stop the etchant there?  From: Homebrew_PCBs@yahoogroups.com

attempt at toner transfer    Do the same traces print
lighter on regular paper? Sometimes the toner inside the
cartridge is used up unevenly after some usage. Try removing
the cartridge and gently rocking it to help the toner powder
distribute more evenly. Print a couple of pages after that
to make sure there's no clumps on the drum, then try
your PCB pattern again.
