Homebrew PCBs

I took a few pictures of laminating the photoresist I have been
experimenting with. The url is

I will additional pictures when I do the exposure.

Thanks Javaguy, a picture is worth a thousand words. I have never used
the soda wash product before but now that I see the box I am sure I
can find it at the store. I am going to start experimenting with the
resist that you sent but I don't have a nice laminator like you (only
a little 4X6" model that I doubt will get hot enough). I do have a HIX
heat press, the kind used to put heat transfers on t-shirts that I
found at a flea market. It has adjustable heat and pressure control as
well as a timer. This might simplify things a bit, eliminating the
need for a carrier as well as the multiple passes through the
laminator. I think I can tack the resist to the board with a tack iron
so it won't slip around while I am positioning the board. I am very
interested in your next series of pictures dealing with exposure and
development.

nice description but I have question on which side of the resist is
against the PCB. The plastic side right or was it

Thanks

Kevin

The laminator cost me about $100, but there are less expensive ones.
Your 4x6 may get hot enough. Never hurts to try.

From what I have read you will have to be careful with the amount of
washing soda you add to the water. To clean up my first mistake I just
dumped some in hot water and soaked. I think if you get it too strong
it could dissolve away exposed parts as well. 

I will be interested in hearing how the t-shirt transfer works.

You want the side you removed the plastic from down on the board. The
mylar side is up.

I may need to make a correction to my descriptions. I said that the
resist was blue because of the plastic, actually you can see blue in
the picture where it is laminated too. Part of that statement was
based on what I had read elsewhere, but when I looked at the pictures
later I realized that does not make sense.

I know the mylar does not appear blue, so at least part of it must be
from the resist.

Hey Javaguy,

Great pic's, very descriptive!  The process for getting this on the 
board looks pretty easy if you have the right laminator.  One 
question, being new to the group, what company makes the photoresist 
and where did you get the material?  I've tried the blue press'n'peel 
with only limited results.  This looks like is could be the best way 
for me to go.

Thanks and Regards,
Phil

I purchased the photoresist from thinktink.com, but the smallest
amount they sell is in 80 foot rolls.

Phil,
If you ask Javaguy nicely he might sell you some of his extra roll.
