Abstract

The major issue that negatively impacts today´s Field Induced CDM (FICDM) tester repeatability and reproducibility is the air discharge´s variable spark resistance. There are many variables that contribute to this measurement uncertainty including humidity, pogo shape, DUT shape, contact alignment, surface cleanliness, approach speed, voltage level and adjacent pin discharges. The air discharge variability is shown and a new CDM test method is proposed that removes the air discharge from the test resulting in superior repeatability and reproducibility while delivering an equivalent CDM stress.
