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.

Hi all,

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 an n-MOS),
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 substrate.

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.

International Electrotechnical Commission

Unfortunately, you have to buy the spec from IEC (not cheap):

For Military systems, the specification is MIL-STD-883, Method 3015.7 (free, compliments of taxpayers)
