Overview

The electrostatic discharge immunity test (ESD) is a complex test with high repeatability and comparability. When there are differences in the test, how to determine the source of the differences has become the main issue in ESD testing. NOISEKEN has launched the ESD specific high resistance and high voltage meter 18-00086B for this purpose. According to the basic principle proposed in section 6.3 of GB/T 17626.2-2018, it can measure the discharge voltage of the ESD generator. The operation is simple and convenient, and a spot check can be conducted before each experiment. This can be used to check the ESD test setup.

Product Details

High voltage meter for static discharge testing point inspection

Generally speaking, the deviation of ESD is mainly concentrated in four aspects:

1. The deviation value of the testing equipment itself;

2. Test the rationality of the configuration and the issue of good grounding;

3. Testing techniques of operators;

4. Environmental temperature and humidity, etc.

The above four situations have caused uncertainty in the final test results. In order to ensure the consistency of the experiment, the GB/T 17626.2-2018 version of the standard specifically mentions the verification of ESD layout, as shown in the screenshot below

The verification method mentioned in the above standards is to discharge the coupling plate and observe the size of the discharge spark to determine. However, this judgment method is not accurate, as we cannot use a vernier caliper to measure the distance of the spark. Similarly, adding a set of gun targets, Faraday cages, and oscilloscopes with bandwidths above 2GHz to verify the equipment is expensive and has low utilization. Not the first choice.

4. The holding voltage obtained by this product includes the voltage drop caused by the built-in 1 T Ω resistor.

The voltage drop varies as follows, depending on the charging and discharging capabilities of the installed CR unit

In the discharge gun: 3.3% at 150 pF; 1.5% at 330pf; 4.9% at 100pf
