Homebrew PCBs

Hi Patrick,

The technique for using laser transparencies is different than 
inkjet and I never got the same results.  Sopry I didn't catch that 
you were using "laserjet" and not "inkjet" transparencies.  Could 
have saved you some time.

With inkjet transparencies, the best results are when the toner and 
board have cooled to the touch.

With laser transparencies, I had the best results when I removed the 
transparency while the board and toner were hot.  You verified what 
I found.  If you let the board and toner cool, the transparency has 
a greater affinity for toner than the board.

If you can find someone to give you a scrap or sell you a sheet or 
two , give inkjet transparencies a try.  The smallest pack I've seen 
is 20 sheets with 30-50 being more typical.  At almost a dollar a 
sheet, that can be expensive if all inkjet transparencies aren't 
equal...

I've only tried HP injket transparencies (not their Premium version 
that seems to be the only one available now).  I'll be trying some 
generic Compusa sheets in a week or two.  The price difference isn't 
that great, but it'll give me another data point to see if it's only 
HP's that work well...

Did you have to do much scrubbing to get the paper residue off?  The 
nice thing about using inkjet transparencies is that the toner isn't 
fuzzy.  Maybe I didn't scrub enough when I tried various papers...

Regards,
Dennis
