Abstract: In one embodiment, a method for determining electrostatic discharge (ESD) includes building a slider delta comparison map using slider electrical and/or row bar quasi testing results, wherein row bar quasi testing is performed on row bars of multiple sliders, and wherein slider electrical testing is performed on individual sliders, determining whether a test device in a parent job passes primary ESD delta criteria, when the test device fails the primary ESD delta criteria: flagging the parent job of the test device as a reroute job and performing automatic actual parts rerouting for any jobs related to the parent job to pull parts from a test bin as opposed to a supply bin, wherein all parts pulled from the test bin are tested prior to assembly as opposed to parts pulled from the supply bin which are not 100% tested.
