Homebrew PCBs

DJ,

Have you tried different brand transparencies?

Before going back to photo etching >10 years ago
I used to do toner transfer from transparencies.

I started doing it in the early 90's after
reading about PARC doing TT in an EA magazine.

Anyway, I found that the transparency had a huge
effect on the transfer.

I got fantastic results with Faber-Castell
OH-LUX.  However these stopped being available
in oz, so I switched to the next best ones I
tried.  This was 3M Brand CG3300.

With the OH-LUX transfers, I would run cold water
over the top as it was still hot.  The totally
clear film would just crack off.  I never needed
to apply so much pressure to squish the traces.

The 3M was not as good and the extra heat/time
they needed would sometimes squish traces.

All the other brands I tried that where
available here either didn't take the toner
well from the printer, or never let go well to
the copper.
