Pads in place

After a round of testing with the base plate open, I wanted to close up the camera with the finger in place.

See how there are two pads visible now.  There's one that is flat against the base with a large area of blue skin visible.  This pad does two functions: it helps protect from shorting on the copper finger and it is another source of cooling near the critical area.  Not sure what the assembly does here, but it can't hurt to have this area cooled.

Deeper inside the camera I've slipped a thin ribbon of pad.  This ribbon goes along the left side of the CCD.  It is not attached to the CCD assembly, rather it is on the main board.  This might help the temperature in this space.  Not sure if it has made much of a difference in testing.

I may remove it or even add more on other areas.  The fit is very tight so it's unlikely that I can get more inside this area.  I also don't want to have the pad touch the CCD assembly that floats because the shake reduction system is still functional.  I don't normally have it turned on, but I want to be able to use the camera as a normal IR camera in the studio or on travel.  Thus everything I do must be somewhat reversible.
