Thanks for pointing that little shop out.
Did you notice this in their whitepaper:
From 1960s to 1980s, Electronic Concepts used Peter Schweitzer
(a Division of Kimberly Clark) manufactured film, the only
United States supplier of material, by license agreement
with Bayer. In 1984, Electronic Concepts acquired the Peter
Schweitzer film division, terminating the license, allowing
Bayer to market the film in the United States. For economic
considerations, Electronic Concepts started manufacturing
capacitors using a balance of Bayer and Electronic Concepts
film.
Does that sound like a run-of-the-mill business decisions made by
a small company which produces capacitors ?
No ?
Then how about this:
In 1990, the conclusion of a polycarbonate film capacitor
paper[1] stated, "both the orientation and crystal structure
of PC (polycarbonate) film affects its mechanical properties
and electrical dissipation factor". The paper was a cooperative
investigation by the Jet Propulsion Laboratory and Electronic
Concepts' film manufacturing division,
Why would JPL study obscure production details of polycarbonate
film capacitors in 1990, if they fell of the market six years earlier ?
Sounds fishy ?
Anybody know what this means ?
Electronic Concepts accumulated almost five hundred million
hours of testing military grade Polycarbonate capacitors;
and, currently meet established reliability failure rate
level "R."
Have you connected the dots yet ?
A fair number of the in-stockpile nuclear weapon designs are qualified
using polycarbonate capacitors and can't be retested, redesigned
or requalified...
