ROME, NY – A pair of trade groups have revised the standard for ESD testing of electronic components.

ANSI/ESDA/JEDEC JS-001-2011 for Electrostatic Discharge Sensitivity (ESD) Testing - Human Body Model (HBM) - Component Level modifies required pin combinations in order to reduce test times, increase productivity, reduce costs and minimize false failures. These changes include: most non-supply to non-supply (I/O-to-I/O) eliminated – testing is limited to differential pairs; eliminated "cross-domain" testing of non-supply (I/O) pins; pin combinations for two-pin testing clarified, and use of "single polarity" supply-to-supply stressing allowed.

The primary changes are described in a new pin combination table; the older set of combinations are still permitted and summarized in a separate table. An expanded annex provides further guidance to allow the user to minimize the interaction between the HBM tester parasitics and the device under tests.
