I stand corrected. When I said 61000-4-2 can be used for testing IC's I considered only the waveform applied. As pointed out by Doug this standard does not define failure for IC's. And speaking of the waveform, I don't think much of it. I measured many human ESD discharges with a metal tool in the hand and the current rise time was much faster than the standards call for. As some ESD protection circuits are triggered by dv/dt, the slower rise time can adversely affect the measurement. Anyone else out there working with TLP's for ESD testing?

In any pin and out any other pin. So 61000-4-2 can certainly be used to test an IC. 4 kV is a common design goal for HBM.

This has inspired me to write an article about it. This month's Technical Tidbit (link is the picture of a chip and ESD simulator at the bottom of the page at http://emcesd.com ) deals with system level test standards being applied to internal devices or modules. If you design or test IC chips or modules that are included in a larger system design, this is a must read article for you. Abstract: A trend in component testing has been developing in recent years. Vendors of system components are being required by their customers, equipment manufacturers, to apply inappropriate system level tests to system components such as chips or modules. One such case of misapplication of a system test to IC chips is explored and implications discussed. Doug -- ___ _ Doug Smith \ / ) P.O.
