Abstract
There are basically two kinds of ESD damage modes for GMR sensors in current GMR head gimbal assembly (HGA) and head stack assembly (HSA) processes: the current damage mode and the voltage damage mode. The current damage mode accounts for most of the ESD damage in actual GMR head production, which indicates that the GMR sensor gets damaged by an unexpected transient current passing through it. This paper discusses the possibility of defining a generic ESD threshold for the current damage mode.
