Homebrew PCBs

I've just uploaded a pic of my latest efforts using an HP LaserJet 5P 
to produce photo-etch artwork on tracing paper:

Photos>Leon's>Photo-etch PCB made with HP 5P

PCB material is Fotoboard (fibreglass/paper laminate) and the board 
was etched in hot FeCl3 with continuous agitation. It took about 5 
minutes. Tracks are conservative - 12 mils.

I'll be tryimng that lead-free solder I mentioned on this board when 
I assemble it. It's actually a simple PIC ISP programmer (PARPIC) 
driven from the PC printer port.

Nice...

you might consider making tha pads bigger, it will be hard to drill/solder 
them.
It might also be that just the hole is too big so it looks a bit odd..

anyway, looks like you could still go down with track with with this 
method easily.

please note that only you and the moderator can see the full size picture 
in the photo section.
If you have high resolution pictures please store in files.

Yes, they should be bigger. That's the standard size I use with 
commercial PTH boards (60/31.5 mil). I could have put teardrops on 
them which would help, but I forgot.

I've uploaded the pic to the Files area, in my Leon folder (pcb.jpg) 
so that everyone can see it in its full glory. 8-)

Very nice boards you've made. I hope mine will eventually come out that 
good!

Thanks. You have to get each stage of the process optimised. It's very easy
and repeatable after that.
