Real time electrostatic discharge (esd) detection

A method for determining electrostatic discharge (ESD), the method comprising:

• 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.

A computer program product for determining electrostatic discharge (ESD), the computer program product comprising a computer readable storage medium having program code embodied therewith, the program code readable/executable by a processor to:

• receive, using the processor, results from slider electrical and/or row bar quasi testing, wherein row bar quasi testing is performed on row bars of multiple sliders, and wherein slider electrical testing is performed on individual sliders and comprises slider-level dynamic electrical testing (SDET);
• build, using the processor, a slider delta comparison map using results of the slider electrical and/or row bar quasi testing, wherein the slider delta comparison map comprises a visual representation of the slider electrical and/or row bar quasi testing results for a parent job to allow for pattern recognition of ESD problems;
• determine, using the processor, whether a test device in the parent job passes primary ESD delta criteria;
• when the test device fails the primary ESD delta criteria:
• flag, using the processor, the parent job of the test device as a reroute job;
• perform, using the processor, 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;
• create an automated report that includes any relevant information regarding the failed test device;
• send the automated report to an ESD team disposed to handle such reports;
• and
• store the automated report and any relevant information regarding the test device;
• when the test device passes the primary ESD delta criteria:
• determine whether the test device passes secondary ESD delta criteria that is different than the primary ESD delta criteria;
• and
• when the device fails the secondary ESD delta criteria:
• flag the parent job of the device as an alert job;
• create the automated report that includes any relevant information regarding the failed test device;
• send the automated report to an ESD team disposed to handle such reports;
• and
• store the automated report and any relevant information regarding the test device.
