Homebrew PCBs

Hi Geoff,

(You asked if anyone had used Glossy Photo paper for
toner transfer.)

I tried the glossy photo paper after a member of this list
strongly recommened Staples brand, part number 19899.
It was the worst stuff I've ever used.  I tried it several times
using different pressure, heats, etc and it was a "non-performer"
compaired to the much thinner inkjet paper I had been using.  I used
my LaserJet-5000 to image both papers.

Best,
Charlie

Hi folks,

New here. I'm Geoff from New Zealand. Have been doing PCBs on and off for
maybe 35 years, first by resist-pen, then Bishop Graphics and Riston.

After a lull of many years  have now tried Press'n'Peel (blue) with a
distinct lack of success.

Printing on Konica-Minolta C353 laser onto dull side of film. Good solid
toner coating. Ironing onto nice shiny clean board at various
temperatures, for up to 4 minutes. Film comes of leaving incomplete
tracks on PCB, some toner and/or some thin remnants of the blue film
coating remaining on film.

Don't know if a factor, but film was purchased over 3 years ago, so may
be quite old.

Here are some pix of my results ( some of film after pressing, and some
of pcb after press. Last pic is 3 patches done at the iondicated
temperatures.

Grateful any suggestions.

Also, I see on YouTube others have tried a similar process using glossy
photo paper, and soaking off - anybody here had with success with that
method ?

cheers

Have decided that I have been unable to get a reliable consistant heat/time 
over the board area with my domestic iron. Have purchased a heat-press off 
eBay (from oz) for A$150ish. Works out economical for my particular project 
in comparison to getting my boards done commercially. And I'll still have it 
for future pcb projects, printing T-shirts, or can sell it on.

No, but may give it a try. You could send me a few square inches sample if 
you lilke

Makes me feel (inadequately !) hi-tech, given your results versus mine !
