Subject: RE: [Homebrew_PCBs] Oven bag method

Steve I agree the prices seem high. That's why I shop at auctions to save
money. I was just trying to show that if you shop around you might be able
to pick one up at a low price. These two examples are the first ones I found
doing a search. PNP does not solve the pinhole problem completely it is
designed so you can have a very small hole in the center of Pads for
drilling and very fine lines.
Tips: when printing always use the darkest setting you can before you start
having shadows or spots. When cleaning the blue off the PCB you can use
lacquer thinner the blue falls off when you wash it with this stuff. Be
careful this stuff is Flammable.

I don't like it when people say it is too hard to do. Not that you are. But
when I first started I could not afford a laser printer. So off to Office
depot to use the copier 10c a copy. Please, any one can find this amount of
coin and go make a PCB. As Nike says Just Do It.

Of course I like others am always looking for a better way of doing things.
What I like about Blue is it costs $1.50 a sheet. I can get anywhere from 9
to 50 PCBs on a sheet on average. That's 17c to .03c per PCB the rest of the
cost is the same as other methods, enchants and the PCB themselves plus
coatings. The only thing I don't like is doing 2 sided boards so a better
method would be nice.

Maybe we can have a poll as to what method everyone is using?

Not to nitpick, but "The temperature of the JP12 is preset at 375
degrees and cannot be changed." Their model further down the page
with adjustable temp is $429.

Again, not to nitpick but the price means nothing until the auction
is over. Between when you posted and now, it went up to $127.50 and
it has days left to go.

PNP Blue is supposed to solve the problem of pinholes in the toner.

That is good to know.
