Can anyone tell me what PCB design parameters would drive the use of Hysol
SR1000 or SR1001 for use as solder mask on a PCB? Why would it be specified
for a specific design over other solder masks? Is there some special reason
for specifying it? Does it have some special property that would make it
preferable to LPI?  I can't seem to locate a data sheet on it to evaluate
its properties.

Sounds like somebody has been watching to much Star Trek.  Next we will have
'Bio-Gell Packs".  I heard copper cable can transmit power pretty well.  The
application may not be to far-fetched if you wanted to get power to an
under-sea amplifier and the IR loss from copper was to high.  But I wonder
if you are violating the Second Law of Thermodynamics here?

        Subject:        [TN] Power over Fiber Optic cable




Is anyone out there doing this...

Has anyone worked with or heard of a process for transmitting power over a
fiber-optic cable?
I believe the theory behind this is to transmit light over a cable and then
convert it to power via a photovoltaic cell or something similar.
I need to respond to a question on a proposal on this subject today.

If you have any information on this topic, please let me know.

Thanks,

Rob
