Most ESD experts consider CDM testing to be the most critical ESD qualification test for modern integrated circuits. ESD control engineers need to know the charged device ESD robustness of all components passing through their manufacturing line. CDM measurements provide that knowledge.
Electrostatic Discharge (ESD) protection of Integrated Circuits (ICs) requires seamless discharge paths and voltage clamping along the course of the discharge, between any pins combinations on the IC.
Absolute Maximum Ratings (AMR) are typically listed on semiconductor product datasheets, warning that overstress results in physical damage, jeopardizing reliability.
TLP ideas are helpful in understanding CDE, but it is an imperfect analogy
This article defines ionization qualification and periodic verification test procedures for ionizers which are not addressed in STM3.1 or SP3.3, including air-assist bar ionizers, soft x-ray ionizers, an alternative method of room ionization, and non-airflow alpha ionizers.
