Homebrew PCBs

I have a friend who wishes to purchase a complete, ready to go, direct 
to double sided PCB inject resist, soldermask, and 
component "silkscreen" system. E.g. a converted Epson printer with a 
reliable feed tray for double sided printing, the MISPRO inks pre-
loaded, the cartridge reseter and everything else required.

He is willing to pay $500. Any interest?

I dont believe that system even works yet, for a SINGLE sided board.  
Paying $500 for a tested, operational do-nothing pcb printing machine 
is also probably a little light.

With all respects to the people that are going in the direction of 
such a system, I think that you are aproaching the PCB making from 
the wrong side. I do not know if all of you that post regarding 
special inks for printers (like a PCB Santa Claus machine) are really 
spending and efforting so much time. If you make a balance between 
the different PCB making techniques, I believe that the winner is 
(consuming less time and effort, with the added-value of the most 
quality finishing) the dry-film methods (ala Thinktink). It is much 
simpler to learn to imaging, developing, etc. properly, that to 
trying to obtain a "really repetable and reliable" procedure with the 
other methods. If I should be waiting for an incredible ink resist, 
or for the most simple method in the world (without any effort of 
mine) surely I did not had maked any PCBs in all these time.

jcarlosmor,
           The direct method started out using floor wax. One guy was
telling people it was a done deal. I milled my circuit boards at that
time. There were people who pointed out that milling could not do fine
traces. While they discounted my efforts I sold hundreds of milled
boards for profit. I could produce a 4" X 6" board with lots of traces
for around $7. The same board done at a place in Texas cost me $16.50
each in lots of 30. Then I went retro producing booklets showing how
to perfboard a project and turn that layout into PCBoard artwork. 
         The direct method now works after years of hard work by a few
people. No matter what method you use you have to stay with it until
you iron out the bugs. All methods give somebody a problem. Just read
the posts.

Around here, affordability is probably the most important factor in 
determining which method is chosen. Ease of use is probably next 
followed by quality. Compared to TT, direct inkjet (when it gets off 
the ground) promises to up the ante in terms of quality and ease of use 
with modest increases in operational costs. Hence its popularity.

Well, since he is your friend, looks like you have youself a job...hehe

Hi folks,

Guess that I've missed the thread about of C84 direct
printing how-to.

Is that used in place of photoresist ?

I could imagine that after visiting: 

www.Rep Rap.org 

understood that there was a possible approach to trace
tracks (URL posted here days ago)

Think it is kinda 'conductive paint', isn't it ?


I don't know if RerRap.org will have a good
cost/benefit ratio for PCBs but think it should be
revolutionary when replicating 3D objects.

Furthermore if the gadget will have a price tag of
$400 next year !


By work experience I'm prone to use film r rather than
other ways  so I can't imagine how the core C84 direct
printing system works 

Hope any reference /link or short explanation about
how direct printing works.

Thanks in advance

Sam

Hi everyone,

Want to share this link with hints about using  the
proven method of film & photoresist :

www.pico-systems.com/PCBs.html

Better yet there can be found a project IMHO for
serious DIYers: a homemade photoplotter !

http://www.pico-systems.com/photoplot.html

Hope the above helps.

Samuel
