Hi All,
I have been writing and recording again, this time on applying system
level ESD tests to devices. If you are involved with either devices
that can be handled by people (for instance a USB thumb drive for
flash memory card) or the equipment they plug into you will find my
latest article and podcast of interest. Any standards people out there?
This month's Technical Tidbit describes a method to simulate air
discharges at voltages above 4 kV in a repeatable way using a modified
contact discharge. This method is especially useful in ESD testing of
solid state circuits using IEC 61000-4-2.
Abstract: Contact discharge is used in ESD testing to improve test
repeatability, yet air discharge has significantly different
characteristics at higher voltages. A test method is described that
uses a modified contact discharge to simulate the characteristics of
an air discharge but with improved repeatability.
The link to the article is the picture of the experimental test setup
at the bottom of the home page at http://emcesd.com . Or just click on

There is also an audio discussion of this article on my podcast site:
http://emcesd-podcast.com where the direct link to the audio file is:

Can't download mp3 files? Download the following instead:
http://emcesd-podcast.com/2006/september/2006-0904.dcs
After download, change the extension from .dcs to .mp3 and the file
will then be able to play on most computers.
