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 .
