When it comes to BC, I have to agree with Simon.....

Since you mentioned it is not a speculation, I presume you can give us some
real example of systems with proper stackup failing ESD test and when BC is
added it magically passed ? Care to share the information ?
************
Your reference to Simon, who states "This topic is absolutely....DREADFUL,"
as well as your "real example" and "magically passed" comments have clearly
negative (and offensive) connotations.
As any professional consultant knows, it would be folly (as well as illegal)
to disclose details on any particular design of a client. However, not by
magic, but through well thought out design techniques, I have successfully
integrated solutions for SI, radiated emissions, and ESD problems to rectify
multiple
hardware designs (on the order of 50-60 different designs out of hundreds of
designs) for Nokia, Boeing, Aerojet Electronics, NASA (Tayco Engineering),
Hewlett-Packard (Systems Div.), Intel (Communications Div.), an international
set-top box manufacturer, a major DNA analysis firm (SF Bay area), United
Technologies, and multiple other major firms, not to mention salvaging two
separate
>$100-million programs by modeling, analysis, and demonstrating corrective
actions using BC concepts. Designs within these companies were aided in the
correction of susceptibilities by the use of BC (both licensed versions and
near-equivalent versions prior to their availability).
As far as knowledge of the benefits and detriments (basicly cost) of designs
incorporating BC, I am confident I have a distinct experience advantage over
you (Chris). I used BC concepts in many edge-cutting military and aerospace
designs before Zycon developed and patented the superior process technology
needed to reliably mass produce same. I contacted them in 1989 to explore their
capabilities, verify through my own tests (in my own lab), and critique their
fabrication and test results. I ended up including their product (ZBC-2000) in
my
seminars and tutorials that covered the US, Europe, and parts of Asia.
Because of my background in advanced military, aerospace, and satellite
systems, I
was aware more than 35 years ago of many beneficial attributes of the BC
concept that still haven't been widely disseminated. I gather, perhaps
incorrectly,
that your experience (Chris) is only commercial and does not penetrate the
glass ceiling of much more difficult design problems shared by many aerospace
companies.
FYI, I only comment to the SI List infrequently as I have many other things
to occupy my time. I never make statements on the SI List that I have not
already proven to myself through both analysis and test to be valid (unless I
clearly state it as a concept for exploration). Nor do I deem it necessary (for
me
or anyone else) to take the time to provide a bibliography of references for
verification of the offered comments. Any such requirement (or request)
discourages the rapid exchange of ideas, comments, and general discussion that
the SI
forum offers, and makes one NOT want to comment. I have in the past and still
do urge all designers with an interest in a given topic/thread to read,
absorb, and digest the comments, and then to THINK IT OUT FOR THEMSELVES as to
the
appropriateness for their particular designs. Most will find that some of the
offered information is not applicable to their current needs, but might
someday be.
There. I think my steam is now released. Time to go trout fishing as the ice
has broken up almost to the dam. My fishing buddy just called and says they
are catching 18-22 inchers on dry flies and midges. This thread is DONE for me.
Good Engineering to all.
