Hi All,

I have some kraft paper for my poly caps but still have some questions.
Should the paper only go between the foil and the poly? My caps will have
three layers of 8mil poly and paper between the foil and the poly, but would
it be wrong to put the paper between each poly layer too. That is
foil-paper-poly-paper-poly-paper-poly-paper-foil. The paper is 2.5mil thick
and should wick the oil nicely. I plan to bake the paper in the oven at
250deg to remove any moisture and vacuum the air out of the capacitor
assembly.
As always any thoughts are appreciated.
Dave
