Standardized Direct Charge Device ESD test for magnetoresistive recording heads II

The well-known Human Body Model is not the most relevant ESD mechanisms along today´s production lines. Damage will most likely occur from metal contact rather than from bare fingers. Discharge waveforms from metal-to-metal contact are of the order of 1 ns, while HBM is 150ns. As there is no standard for Direct-Charged Device Model in the literature yet, the purpose of this work is to propose and define the first standard for D-CDM testing. This standard is based on manual discharge data. We further investigate if existing D-CDM tools meet this standard: ISI D-CDM and T.E.T ESD/CDM tools are reviewed.
