DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-spark generator, and more particularly to a multi-spark generator for generating a controllable, reproducible and practical electrostatic discharge and detecting sensitivity in electronic equipment based on computers and microchips. Related to the device.

2. Description of the Related Art One of the main causes of failure in electronic equipment based on computers and microchips is due to electrostatic discharge. In everyday work and daily life, various materials use static electricity due to friction. Easy to do,
Synthetic materials are one of the typical ones.

When two materials of different materials come into contact with each other, electrons are attracted from one to the other due to friction, instantaneous separation or the like, and as a result, different charge voltage levels are generated in the individual materials. This is static electricity. Depending on the combination of certain materials, static electricity of several thousand volts is generated due to friction or instantaneous separation.

When walking on a carpet made of synthetic material in a cold and dry climate, static electricity of several thousand volts is generated, and when touching a conductor, pain is felt or sparks are seen. Also, in a cold and dry climate, sitting on a chair made of synthetic material and moving left and right can generate thousands of volts of static electricity. You can see sparks. This is the so-called electrostatic discharge (ESD: Effec
t of Static Discharge).

[0005] ESD frequently occurs in daily life, especially in cold and dry climates, where it occurs frequently in offices and homes due to low indoor humidity. Electronic products based on computers and microchips are closely related to people's work and life. Therefore, in order to improve the quality and reliability of products, electrostatic discharge (ESD) and ESD are required for computers and microchip-based electronic equipment.
It is necessary to perform a magnetic field interference test caused by the above.

At present, the International Electrotechnical Commission has established a 1000-4-2 ESD simulator (IEC1000-4-2 ESD Simulato).
r) The electrostatic discharge (ESD) test is performed using two patterns of contact discharge and air discharge.
According to the -2 document, contact testing is the preferred method. In the contact test, equipment (EUT: Equipme) where the user should test an electrostatic simulator (ESD Simulator)
nt under test), and the discharge current of the capacitor flows into the equipment under test via the contact point directly by the relay contact. If the test point is a metal, the manufacturer is required to perform a contact discharge test. If the contact discharge test cannot be performed, an air discharge test is used.

Although the contact discharge test can be reproduced, a practical ESD current cannot be generated. In the air discharge test, an electrostatic discharge simulator according to IEC1000-4-2 is first charged and then discharged to the equipment under test adjacent to the equipment to be tested (EUT). However, due to various environmental influences, the air discharge test is out of control and cannot be reproduced.

Furthermore, the contact discharge test and the air discharge test both require a ground wire connecting the equipment under test and the generator, and the test results are not clear.

[0009]
