RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

ESD HBM model Test Bench - RF Cafe Forums
RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media
platforms dominating public commenting venues. RF Cafe Forums began sometime around
August of 2003 and was quite well-attended for many years. By 2010, Facebook and
Twitter were overwhelmingly dominating online personal interaction, and RF Cafe
Forums activity dropped off precipitously. If the folks at
phpBB would release a version with integrated
sign-in from the major social media platforms, I would resurrect the RF Cafe Forums,
but until then it is probably not worth the effort. Regardless, there are still
lots of great posts in the archive that ware worth looking at.
Below are the old forum threads, including responses to the original posts.

I am building a HBM ESD test bench
and I came up to the following question:
When I connect the ESD
protection circuit and the theoretical input to the main circuit (ie
what I put as Vcc and Vee voltage of the ESD?
My original idea is to leave it floating. But then, floating means arbitrary
voltage in the power lines.
My second thought is to put both
VCC and VEE inputs to the same node which eventually is connected to
The second approach shows a well operating ESD
protection scheme. But is it the correct one, meaning, is it the one
corresponding in the real situation?

IEC 61000-4-2 lays out all
of the "official" tests for ESD testing.
Unfortunately, you have to buy the spec from IEC (not
For Military systems, the specification is MIL-STD-883, Method 3015.7
