Asian toner transfer paper

Asian toner transfer paper

2016-08-26 by Brad

Bought a whack of this on ebay.. I’m just wanting to check.. is it intended that you print on the dull side or glossy?  Thinking it was like press n peel, I tried first on the dull side, but adhesion was minimal.  Then I tried dull side.. much better.  But still missing some fine traces.

 

Thanks!

Brad- It should be the glossy one.

I had awesome results with mine when I first got it (using an Apache laminator), but I broke the stuff out again recently to do a board and it was a mess. Can't think of anything that changed, but I'm going to have to work it out before I fight with it again.

Also, the arrival of the yellow paper was when I first started using the green TRF. From what I remember, the transferred image all stuck perfectly, but was sort of "faint" in many areas (especially solid pours), which is weird, because it didn't seem to leave any toner on the paper. The green stuff on top of it gave me a perfectly clean image. Not sure I would recommend running without it.

Thanks!  That’s what I was kind of thinking.  My printer is not too wild about this stuff… even on heavy gloss setting it’s not putting quite enough toner down.

I just did a power supply brd with white glossy on one side of paper and dull other side bought from orient over a year ago. Use glossy side only. I use a HP LaserJet P2015dn printer with a freeware program to get to 1200dpi. Print came out beautiful.
A Scotch laminator followed by a household Iron completed that part of job. Next the board went thru the laminator then household iron with the pulsar pro green TRF.
Everything checked out A/OK so I etched the board with Muratic Acid and hydrogen 
Peroxide and board looks great. Go out and buy Green TRF it really works at protecting traces and pads. Have not tried small 10mil traces thou.

Brad (sorry, hadn't checked in here for a couple days),

Yeah, the yellow paper is weird like that. I have a feeling you have to use that TRF with it. Like I mentioned, it doesn't seem to leave anything on the paper though. Usually when there are breaks,etc. with the normal paper, there will be little bits of toner still on it. I have no idea where it all goes with this stuff, but like you, I'm running at a pretty dense (black) setting, so there should be plenty.

On the plus side, that successful first board with the yellow paper and TRF was beautiful. It looked like a silkscreen, so it's well worth using, even if you have to get foil to go with it.

Still need to figure out why my last board was such a hassle though. Not only did the toner not take for a couple tries, but the TRF didn't work well either, so I'm guessing it was a laminator issue.

The laminator rollers need cleaning due to the surface degradation
(powdering/stickiness) from high heat cycling. This causes the roller to
tug on and flex the transfer paper backing as it passes thru the rollers
while still hot, making for breaks or poor toner bonding or foiling
before it has cooled enough.

IPA can work, but, the best solution I have found is to clean once and
wrap completely in Kapton tape. Kapton does not heat degrade and
maintains an easy to clean surface.

I like the Apache AL13P because you can also swap the two cold rollers
for the hot ones when doing the kapton wrap and disassembly is easy.

What is the width of that Kapton and how can that be affordable as I looked into prices? What is your source of Kapton?

I used this:
Ebay # 291843905734.

Had lots left over , can do quite a few rollers.

To wrap properly you need someone to hold the roller and slowly rotate
it while you maintain tension on the Kapton tape reel for a firm bond
with slightly overlapping continuous feed to accomplish the wrap. Much
like winding an electromagnet.
