Re: [Homebrew_PCBs] Cold toner transfer FAILURE

2016-10-06 by alan00463@...

Tried another transfer using ORACAL 651, using a mixture of  half
acetone and half denatured alcohol    Followed Harvey's directions
and burnished the artwork backside with the backside of a fork
following DuWayne.   The artwork did not transfer.

Tried it again with the same mixture.    This time I put the copper
clad board between two steel plates that I marked with a red Sharpie.
I squeezed them together for ten minutes using two medium C clamps.

This time about a third of the toner transfer from the artwork to
the copper clad--in the middle of the board.    PARTIAL SUCCESS...

Next time, try applying pressure with a pipe clamp.   Better yet,
get a 6-inch brayer.    I see the brayers come in either hard rubber
or soft rubber.   Which kind did you get, Harvey?   I've never used one.
