Interesting update ..
I have this thin board .. 0.031 thick
and have had a difficult time getting the toner to
stick good to it. The thicker stuff seems to be better.
How does this relate to toner curing?
Well .. I have my new Apache 13P 4 roller laminator ..
and did one board .. and some of the transfers came off..
It was that thin laminate again .. so I cleaned it up and
tried it again .. but this time .. I thought .. being the rogue
that I am .. that perhaps I could quench it then cure / bake it
WITH the paper on .. Well that was interesting ..
The paper dried out .. and getting that first layer off was a little
tricky .. but as much as it seemed to be more stuck to the board
I expected it to pull the trace toner patterns right off the board.
But, if did not . So I threw the board back into the water and
went to work .. Just got home .. and worked a fair bit harder getting that paper off the board .. and was rubbing it remarkably harder
then the first board... The toner stayed on the board. Nothing came off .. Sooo I believe at this point in the adventure that baking / curing ... or whatever its doing to the toner .. is definitely making it adhere better to the board ..
Thats about it ..
Hope it might help someone out there ...
