ESDC 30 system

Description
Considerable efforts have been made to reduce the weight and the size of the test pistol to an absolute minimum. The shape has proven to offer optimal ergonomics when working with contact discharge as well as with air discharge.

The ESD generator is divided into two parts. A small and lightweight pistol only containing the necessary high voltage electronics and a controller containing all the control and user interface. A thin and highly flexible cable with no voltages exceeding 24V connects the two parts.

The pistol has the following characteristics:

  • Low weight, only 440 grams., with a good 'balance' insuring a pleasant working situation, even for longer periods of time
  • One button for discharge
  • Simple change between different test fingers
  • The standard - ESDP 33 - pistol is equipped with 330 ohms / 150pF discharge network
  • A special pistol - ESDP 15 - conforming to the IEC 801-2 (84), equipped with 150 ohms / 150 pf discharge network is available

The controllers characteristics:

  • Easy and intuitive operation with soft-keys and function keys
  • Readable high contrast display with backlight
  • Programming facilities
  • User memory and library inc. level I - IV according to IEC 801-2 and IEC 1000-4-2
  • Portable with the possibility of battery use
  • Possibility for automatically interruption of test at EUT failure
  • Automatic detecting of test finger present

A new and unique function in the ESD simulator is the so-called fail/stop function. The fail/stop function makes it possible to halt a programmed test or sequence when the EUT fails and this fault is detected by a control circuit. The fail/stop function is controlled by a optical fibre input. There exist thus no galvanic coupling between the EUT and the simulator which can create problems.

The combination of the fail/stop function and the possibility of halting a test sequence is particular useful when examining if is a change made is for the better or worse.

Programmed test sequences can easily be saved in the user memory for later use. It is therefore easy and accurate to repeat a previous test.

Pistols with other discharge networks are available on request.

Abstract continued ...
The ESD generator/simulator is a part of the immunity standards described by the International Electronic Commission (IEC). The IEC 1000-4-2 standard specifies a method of establishing a common and reproducible basis for evaluating the performance of electric and electronic equipment when subjected to ESD pulses. Two methods are described, contact discharge and air discharge.

In contact discharge mode (point tip test finger) galvanic connection with the EUT is made first and thereafter is the discharge made by means of the built-in high voltage relay.

In air discharge mode (ball tip test finger) the pistol is first charged (armed) and thereafter is the test finger lead towards the EUT at high speed until a spark appears between the tip of the test finger and a conducting part of the EUT.

The air discharge method is usually used in those cases where no direct discharge part are visible or accessible, or where the surface is declared insulating by the manufacturer.

Because of the steep edges of the pulses - up to 0.7 ns - they create a high level wide frequency spectra causing equipment to fail.

In real life ESD pulses are generated when e.g. a person gets charged by walks over a synthetic carpet and thereafter touches a large metallic object leading to a spark (ESD pulse).
