Field induced cdm
WebThe current industry standard testing method is the Field Induced CDM (CDM) method governed by the ANSI/ESDA/JEDEC JS-002 standard [1]. Current CDM testers are plagued with repeatability issues due to the variable spark resistance of the air discharge making the practice difficult to standardize [1, 2]. Web“In order to mitigate field-induced CDM (Charged Device Model) damage, the ESD program shall include a plan . for the handling of process-required insulators. If the field exceeds 2,000 volts/inch, steps shall be taken to either: A. Separate the insulator from the ESD-sensitive device by a distance of 30 cm (12 inches); or
