Hi All, I have posted this month's Technical Tidbit titled "Filtering Contact Discharges - Part 2, High Pass Filtering (for troubleshooting or simulation of ESD from small objects)."
The article describes a method to high pass filter contact discharges >from an ESD simulator. This method is useful for troubleshooting ESD problems in equipment or simulating discharges from relatively small metal objects. Abstract: High pass filtering of an ESD contact discharge can be used for troubleshooting ESD problems with equipment or simulating ESD from small metal objects in a repeatable way. A method is described for constructing a simple coaxial capacitor to provide a high pass filter that leaves just the initial peak of the hand-metal ESD waveform while attenuating the low frequency components. The link to my University of California Santa Barbara seminar to benefit the University on November 1 is: http://www.ece.ucsb.edu/Research/HFFA2006/ All proceeds from the seminar go to the University. Most of the troubleshooting methods covered in the course are very effective and not taught by anyone else, a great excuse to spend a day or two in Santa Barbara. Doug -- ___ _ Doug Smith \ / ) P.O.
