Homebrew PCBs

I think the proximity of the holiday might have alot to do with the 
lack of corrispondance.

 I am trying to figure out a way to get some light sensitive PCB's 
transfered. I have heard that one can simply print out the layout to 
a plain peice of paper and use that directly 'mated' to the bare PCB 
to effect the transfer process.? I don't want to waste a board trying 
this out so am posting instead! Has anyone had luck with this method 
of transfer? Most others would use some poly film or whatever else 
but I have none suitable and the stuff I do have cannot be run 
through the printer I don't think, else it melts due to the newer 
laser type printer I have to use since my old HP conked out this 
weekend.

 What are others thoughts on this process? The layout itself is 
intended to be fairly complex- most of the parts are small SMT and 
the whole reason why i am trying tghe PCB method rather than just p-p 
like I usually do!!!

 Also, does anyone know for SURE if I can print out 
a 'toner=transfer' layout using a newer styled printer,,ie. HP 
laserjet 1200 series? I'm going to try anyways but just wanted to 
check in advance to see what I can expect....

 Thanks in advance, jd

I normally use vellum in a fancy laser
printer that gives me very good contrast.

If I dont have any vellum or am not near
tha printer I will just use plain paper
in a normal laser printer.

The plain paper works better than vellum
in a normal laser.  However the exposure
time is 10 times longer and I can only do
10thou reliably with plain paper.

use magazine paper, works OK

I use an HP Laserjet 1200 at home for my TT, it works great. Between
that and the 8000 series at work, the 1200 does the best job.  I'm
also using it with a rebuilt cartridge and the results are just as
good, both for TT and regular printing (gotta order some more
cartridges from that place).

Also, never tried the photo process with anything other than Laserjet
transparency film.

Thanks for the info! I actually tried printing off a bunch of layouts
this morning using the printer and have found that it is more
'forgivable' than my previous HP deskjet in that it will accept
various thicknesses better without getting all 'bunged up'- I had to
tape the transfer paper to a regular sheet and feed it through like
that- it worked out just fine! I still need to do the iron on transfer
but will do so later.

 One thing that is giving some problem is that the printer I used is a
work printer, attached to machines which are not able to have software
installed- so no eagle on these machines! My alternative was to
download Primo PDF and print to file at home on my dev box to a disk,
take it to the work machines and use the already installed Acrobat to
interpret and send to printer. While this is effecitive to a degree, I
am finding that there are minute differences in the printed layout as
opposed to other examples I have at home which were printed directly
from Eagle to paper. The variation is very small, but will pose
serious problems in SMT components. Thru hole I could likely work
around- but this is unacceptable in general so I need help with
it--many others have used this software with success so I think I am
just doing something in err, something stupid no doubt! Ideas???

 Thanks in advance, jd

 PS for the UV development process I am just going to have to try
using paper for now as my Deskjet gave up the ghost over the weekend
and I doubt that the work printer would work correctly with the
transparencies I have--melters...jd
