For imaging, you could laminate them with a hot clothes iron and expose them
outside on a sunny day. Probably want to be at the equator on the solar
equinox to prevent undercut and maintain proper line width.
Of course a swimming pool with sodium carbonate would be perfect to develop
them in. They could be towed around in a little row boat to assure even
solution flow across the panel for uniform developing.

Geez, I need a vacation.

Hey Guy,

I can't say I've every seen or heard of an exposure unit that large or a lam
press if it's multilayer that it could fit in.  (You'd need a crane for the
caul plates.)

It must be Friday.

Anybody know where we can get quotes on 4 by 8 boards. Yes, four foot by
eight foot boards. We do not need through hole plating but we do need images
on both sides, oh yeah and thin 1mm or so.
