Introduction to Electrostatic Discharge (ESD) and Its Impact on Electronic Systems<\/h2>\n

Electrostatic discharge (ESD) is a transient transfer of electric charge between objects at different electrostatic potentials, capable of causing catastrophic or latent damage to electronic components. Industries such as automotive, aerospace, medical devices, and telecommunications rely on rigorous ESD testing to ensure product reliability. ESD generators simulate these discharges in controlled environments, enabling compliance with international standards like IEC 61000-4-2 and ANSI\/ESD S20.20. <\/p>\n

Core Principles of ESD Generator<\/a> Operation<\/h2>\n

ESD generators replicate human-body model (HBM) and charged-device model (CDM) discharges through high-voltage circuits and discharge networks. The LISUN<\/a> ESD61000-2C<\/strong> generator, for instance, delivers precise waveforms (4 kV contact, 8 kV air discharge) with a rise time of 0.7\u20131 ns, adhering to IEC 61000-4-2 requirements. Key operational stages include: <\/p>\n

    \n
  1. Charge Accumulation<\/strong>: A high-voltage power supply charges a storage capacitor (150 pF for HBM). <\/li>\n
  2. Discharge Triggering<\/strong>: A relay or semiconductor switch releases the charge through a 330 \u03a9 resistor (HBM) or direct contact (CDM). <\/li>\n
  3. Weryfikacja kszta\u0142tu fali<\/strong>: Oscilloscopes verify compliance with standard current waveforms (e.g., 30 A peak at 4 kV). <\/li>\n<\/ol>\n
