What is the meaning of ES tester?ES refers to Electrostatic discharge, which is the phenomenon of instantaneous discharge of electric charge between two contacting objects.ES tester is mainly used to detect the electrostatic discharge of various electronic devices. According to national standards, electronic products need to be tested for electrostatic discharge at the manufacturing stage and before entering the sales market to ensure the safety stability and reliability of the products.
What is the working principle of ES detector? It is through the discharge needle and grounding plate and the object under test to form a capacitance, and then through the voltage amplifier, filter, etc. for signal conditioning and stabilization, and then finally by the computer for digital processing and display test results. The tester can not only detect the intensity and waveform characteristics of electrostatic discharge, but also identify different discharge impedance and quantitatively analyze the discharge process.
ES tester is widely used in which fields? With the development of electronic industry and high-tech industry, ES detector has become an important tool for electronic product quality inspection and prevention of static electricity problems. It is widely used in electronic components, analog integrated circuits, computers, communications equipment, medical equipment, automotive and aerospace fields. At the same time, the ES detector is also one of the necessary equipment in some research institutions and university laboratories, and is widely used in scientific research and teaching work.
