Charged Device Model (CDM) ESD Test System for Integrated Circuit Evaluation
Leave a Message
The Charged Device Model (CDM) ESD Test System for Integrated Circuit Evaluation is a precision electrostatic discharge immunity testing instrument engineered for semiconductor component reliability validation during manufacturing, handling, and assembly operations. This system simulates the instantaneous discharge phenomena that occur when charged semiconductor devices—typically through triboelectric or inductive charging mechanisms—establish contact with grounded surfaces such as test fixtures, printed circuit boards, or automated assembly equipment.
By implementing precise control over discharge voltage parameters and current waveform characteristics, this instrument evaluates component tolerance thresholds to CDM-type electrostatic events. The system proactively identifies potential failure mechanisms—including internal circuit degradation, gate oxide breakdown, or functional impairment—associated with charged device discharge scenarios. This provides essential validation data for semiconductor reliability engineering, production quality assurance, and international compliance certification processes.
The CDM ESD Test System incorporates an integrated charge injection and contact discharge architecture, addressing limitations of conventional CDM testing equipment regarding operational complexity and waveform stability. The system features a high-precision charge measurement module that monitors device charge accumulation in real-time, maintaining discharge voltage accuracy within ±3% tolerance. Customizable semiconductor device fixtures support industry-standard package formats including DIP, SOP, QFP, and BGA configurations.
An integrated Android-based touchscreen interface with multilingual support (Chinese/English) enables single-touch test parameter configuration, automated discharge sequence control, and real-time data acquisition of voltage and current waveforms. This comprehensive functionality enhances testing efficiency and measurement repeatability for semiconductor ESD evaluation, meeting industry requirements for precision testing methodologies in accordance with JEDEC JS-002 and AEC-Q100-011 standards.
