DIY PCB toner transfer

[[email protected]]

I don't make my own PCBs, but something I've not seen mentionned in the
laser toner transfer technique is that the paper backing for adhesive
labels is perfectly calandered (ie smooth) and will gladly release the
toner with just a bit of heat. The bonus is that this type of paper is
free. Just look out for the lines where the die-cutting blades cut.
Basically you just print on the smooth side and there you go.

I've used Corporate Express EXP00716 labels and made a test etching for
a mixer board. I think it went fairly well, but I never soldered to it.
(I just plop the parts right on the mixer, it works)

I believe the idea is that this paper won't grab to the toner
preferentially to the rougher copper surface.

Anyways I just thought I'd toss that out there. Do with it what you
will.

Neat...Might try someday..
On that topic..
If you're experimenting with spray coatings on laser transparency
film, please post the results.
It's related to my post entitled "pirated press n peel"..

This works great! I always used the photo methode but this is so easy with
very good results. 0.3mm tracks are no problem. Look here how to do it:

transfer'.
I use 170 gr. photo paper with a laserprinter. You can also make a silk
screen the same way (only black) which make it even more professional.

I've used label backing for other iron-on projects and found it works well.

IIRC Avery make one with a full-page sized label (so no cutting lines)

And it's reusable.

You can run the paper through multiple times for extra darkness if you're
careful with registration.
