The invention belongs to the field of electro-static discharge (ESD) resistant capacity testing technology of electronic components and particularly relates to a testing device and a method with ESD resistant capacity. The testing device with the ESD resistant capacity comprises an ESD testing platform, a locating device, a to-be-tested component and an electro-static gun. The locating device is located above the ESD testing platform. The to-be-tested component is placed in the locating device. The testing distance of a discharge end of the electro-static gun and a surface of the to-be-tested component is fixed in a certain standard value through the locating device. According to the testing device and the method with the ESD resistant capacity, according to different requirements of air discharge and contact type discharge, the height of a lift support is finely adjusted through a height control device, so that in a air discharge test, the condition that the testing distance of the discharge end of the electro-static gun and the surface of the to-be-tested component is fixed in the certain standard value is satisfied, different design and manufacture can be conducted according to the size of the to-be-tested component so that the requirement for locating in the test is satisfied.
Description
technical field [0001] The invention belongs to the technical field of testing the anti-ESD ability of electronic components, and in particular relates to a testing device and method for the anti-ESD ability. Background technique [0002] ESD (Electro-Static discharge, electrostatic discharge) is a subject formed since the middle of the 20th century to study the generation, hazards and electrostatic protection of static electricity. Therefore, it is customary in the world to refer to the equipment used for electrostatic protection as ESD, and the Chinese name is Static resistors. [0003] Static electricity is an objective natural phenomenon that can be generated in many ways, including contact, friction, and induction between electrical appliances. Static electricity is characterized by long-term accumulation, high voltage, low power, small current and short action time. It can be said to be ubiquitous in our daily life. For example, the static electricity of a chemical fi...
