From the technical point of view, the more precise term for this phenomenon would be static electricity discharge. In the Beginning Electrostatic discharge ESD phenomena have been known since the Greek civilization was dominant thousands of years ago.
Further information on the IEC is available from www. This article is primarily addressing the interruption effects of ESD to packaged electronic equipment. Summary Electrostatic discharge testing has evolved from a company-based reliability test in the s and s to a performance test on electronic products in the timeframe.

The EMC Engineers went back to work; they placed a metal ie plane under the all-plastic cash register and discharged to the metal ground plane now known as the HCP to simulate the real-life experience. People in cold climates were very familiar with the ESD effect in a low-relative humidity environment as was frequently experienced in indoor environments in the winter time. Menu Skip to content. Kangaroo Leather One computer company in the s began experimenting with ESD relative to its computers and computer peripherals.
In most cases, the companies started at a recommended 5 kilovolts amplitude; when the companies products could all pass that level, the consultants would recommend volts amplitude and so on! Monitoring Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work.
The edition did have a requirement for discharging to the earth reference plane to simulate discharges to objects jec the vicinity of the Equipment Under Test EUT. Includes electrostatic discharges which may occur between electrostatically charged objects brought together near to the vital instrumentation.
The requirement is for electronic products to operate successfully when subjected to ESD phenomena representing the real-world environment as simulated in an EMC laboratory. The test was an air-discharge test. Elektromagnetische Vertraeglichkeit von Mess- Steuer- und Regeleinrichtungen in der industriellen Prozesstechnik. Iecc more about subscriptions. Worldwide Standards We can source any standard from anywhere in the world.
The key parameters of the ESD Generator remained constant at pF for the energy storage capacitor and the discharge resistance is ohms.
This ensures 68001 you are always up-to-date and saves you both time and money. The s and s saw individual companies developing their own test values and test techniques. For further information, contact Dan at danhoolihanemc aol. The grounding cable from the VCP and the HCP to the ground reference plane had kohm resistors located at each end of the cable. The polarity of the output voltages was both positive and negative. The output voltage was up to 8 kVolts for contact discharge and 15 kVolts for air discharge; isc positive and negative.

The international standards organizations irc involved in the s with the release of IEC on ESD limits and test methods. The output voltage for contact discharge remained constant at a highest value of 8 kilovolts and the air discharge at 15 kilovolts. A common discharge value for early standards was volts. Therefore, it has been decided to retain the term ESD in the title.
