I tried this using a pizza stone for higher energy accumulation.
Nada. There is something in the 'massaging' and that something being
a mix of temp and force pers iron's surface. I still believe that TT
is a great method for something simple, wide and small. To have real
quality one following choices:
1. Inkjet w/conductive ink. SOBs already make that ink but I found
out that they are making machines that go with it. This will be the
future of PCB mfr-ing.
2. I won't even mention isolation milling with CNC machines (sorry
Dave...) because of dust and freaking noise.
3. Laser--- I read with interest couple of posts on the subject... if
that works out then it is a great technology.
4. And the winner is: PHOTO. There is no substitute for a UV
exposure. But to have a quality product one needs an extensive
hardware setup.
I saw today a machine that is used to print images on CD/DVDs. Cost
was more than 100k and when asked about my cost to order a volume,
teh answer was: er...60cents per disk. Regretfully they cannot print
larger than disk.
5. I've seen a laser etching in action and have to admit that it is
an awsome technology. But... the laser cost around 100k, all the
safety precautions but quality was stunning.
so many words for today. Back to my project perfecting the photo
imaging.
