The ESD-CDM system mainly consists of three parts: DC high voltage source, Main instrument and electrostatic test probe (including attenuator). It can realize the electrostatic induction charging, electrostatic discharge and discharge signal acquisition test functions of the charged device model (CDM). Note: ESD-CDM can share a host with the ESD-883D HBM\/MM ESD Simulators<\/a> to test HBM, MM and CDM at the same time (LISUN model: ESD-883D\/ESD-CDM)<\/p>\n

Test Operation Process:<\/strong>
\n1. Place the DUT on the insulation board, fix the fixture, and face the pin upward;
\n2. Manually adjust the three-dimensional knob of the base to make the pin of the DUT in the center;
\n3. Manually control the test probe to the maximum displacement, confirm that it is in contact with the pin, and then restore its position;
\n4. Set the probe movement speed to an appropriate value;
\n4. Start the high voltage source to XX volts to put the DUT in an electrostatically induced charged state;
\n5. Make the probe automatically move down quickly and contact the pin to complete the CDM discharge process. At the same time, the discharge waveform data is transmitted to the oscilloscope via a coaxial cable for display and storage.<\/p>\n
