Hi
did anybody face problems while printing layouts on transparent
paper using HP Deskjets ?
mine isn't doing a good job. the printing is very poor

You can't use a DeskJet that is a inkjet printer. You have to use a laser or
copier that has toner in it. Inkjet is liquid and toner is a powder which
uses a heat process to bond.

I don't think he's doing toner transfer, I think he's trying to
make a BW photomask.

I have never been impressed with HP's inkjet printers.

I have heard people say they print on two transparencies and stack
them to get a darker black for photoetch masks. I've also heard of
people using fairly transparent parchment paper instead of
transparencies, print mirror image and place image side down on the
sensitized copper board.

The best inkjets are epson stylus colour (in black mode)
because they have the best transparencies.

Well, quality of an inkjet photomask can vary a lot depending on the ink
and how is reacts with the receptive coating. As russell pointed out
Epson ink and epson transparencies work brilliantly. All of the HP
inkjets with HP transparencies I've seen give poor results (lots of
micro holes and even some banding !!). Epson transparency with HP ink is
equally poor. HP transparencies with Epson printer give barely
acceptable photomasks but only on print settings 1440dpi more/photo
paper, where maxium amount of ink is printed. A friend just bought one
of the new cannon inkjet printers which I think uses dye based black
inks just like the Epson. I've only seen the results on glossy
photopaper, but the artwork is extremely dense and solid. I'm going to
try it with various brands of transparencies and see what I get. The
Cannon is cheaper to run (bigger ink storage) than the Epson.

Just wondering if anyone has run across something on building a small
dip soldering setup.

Someone (I thought it was on this list) mentioned they had seen a small
setup that was more or less a set of rails running through a solder pot.
The board to be was put on the rails or angle and simply pushed through
the solder by hand.

Anyway just wondering if anyone has run across info on how to do this or
what to watch out for when doing this.

Tnx

Dave
