A Brief History of Electrostatic Discharge Testing of Electronic Products | In Compliance Magazine

This article is primarily addressing the interruption effects of ESD to packaged 6081 equipment. Webprint Printed and bound. From the technical 6801 of view, the more precise term for this phenomenon would be static electricity discharge.

Most electronic companies in the s and s were aware of and concerned with ESD. In the Beginning Electrostatic discharge ESD phenomena have been known since the Greek civilization was dominant thousands of years ago. Applies to the susceptibility of industrial-process measurement and control instrumentatiion to electrostatic discharges generated by operators touching 660801 instrumentation and to electrostatic discharges generated between objects in the proximity of this instrumentation and establishes severity levels and the required test procedures.

Note that there is no ground reference plane on the floor, the earth reference plane is on top of the table and it is grounded to a mains terminal earth connection via a cable. A Van de Graaf generator, some high-voltage 6081, and a green nylon carpet were all tried as potential ESD generators. The values of the parameters of the discharge current had to be verified with a 1 GHz oscilloscope.

See Figure 5 of IEC for the illustration of the test set-up for table-top-mounted equipment, laboratory tests Figure 1. Stoerfestigkeit gegen die Entladung statischer Elektrizitaet.

Electromagnetic compatibility for industrial-process measurement and control equipment. The output voltage was up to 8 kVolts for contact discharge and 15 kVolts for air discharge; both positive and negative. Needless to say, the lab made that fact known while in parallel it developed an engineering fix to its product to allow it to pass 18 Kilovolts. Summary Electrostatic discharge testing has evolved from a company-based reliability test in the s and s to a isc test on electronic products in the timeframe.

One of the major changes in the standard was that the contact discharge was the 608001 test method not the air discharge method. The development of the HCP started with a well-known cash-register company in the s. In most cases, the companies started at a recommended 5 kilovolts amplitude; when the companies products could all pass that level, the ifc would recommend volts amplitude and 60081 on!

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. The parameter of the ESD Generator stayed constant from the — standard; that is, the energy storage capacitor was pF, the discharge resistance was ohms, and the output voltage of 8 kV for contact discharge and 15 kV for air discharge.

IEC 60801-2:1991

The rise-time at 4 kilovolts had decreased to 0. The amplitudes were quoted in both the negative and positive polarities. A common discharge 608001 for early standards was volts.

As electronic components changed from electronic tubes to solid state electronics in the s, companies became concerned with damage to electronic components and interruption of normal operation of electronic equipment.

The EMC Engineers went back to work; they placed a metal ground plane under the all-plastic 608001 register and discharged to the metal ground plane now known as the HCP to simulate the real-life experience.


The standard carefully pointed out in a NOTE that: Electrostatic discharge requirements Status: While they were developing the HCP, they realized the HCP could be turned on its side to represent a vertical metal file cabinet and they proceeded to design the cash register to pass that test also that HCP on its side is the present-day Vertical Coupling Plane VCP test.

The companies tended to have proprietary standards and test methods on ESD and were not interested in exchanging information with their competitors on ESD. There were some companies that were using a contact discharge approach to ESD where the ESD tester was in physical metal to metal contact with the electronic equipment.

The engineers took the Australian engineer into the controlled environment and asked him to shuffle his feet while connected to the electrostatic voltmeter.
