Could you elaborate on the folded cardboard? I'm having a problem
visualizing exactly what you are doing. I'm assuming you tape the
copperviews to maintian alignment, and then slip them into the folded
over cardboard to hold them and the pcb laminate static during the 2
passes through the laminator.

Also, did you have to mod the laminator to deal with the thicker
stack? Then again, I tend to think of cardboard as 3-4mm thick,
perhaps what you are using is thinner.

Currently, I use a Kepro exposure system, and it works extremely well,
but the time savings for TT are making me think of revisiting the process.
