Abstract
A production failure analysis system including a factory quality control unit configured to transmit a trigger signal when a production failure is detected, and an analytics unit. The analytics unit is configured to determine a root cause of the production failure by at least receiving the trigger signal from a factory quality control unit, extracting production data from a database when the trigger signal is received, wherein the production data includes process input variables, and identifying one or more potential root causes of the production failure based in part on an analysis of the process input variables.
Claims36
A storage device production failure analysis system comprising:
- a factory quality control unit configured to transmit a trigger signal when a storage device production failure is detected;
- and
- an analytics unit configured to determine a root cause of the storage device production failure by at least:
- receiving the trigger signal from a factory quality control unit;
- extracting storage device production data from a database when the trigger signal is received, wherein the storage device production data comprises process input variables;
- and
- identifying one or more potential root causes of the storage device production failure based in part on an analysis of the process input variables.
A method for determining a root cause of a storage device production failure for a storage device production failure analysis system, the method comprising at least:
- receiving a trigger signal from a factory quality control unit, the trigger signal generated when a storage device production failure is detected;
- extracting storage device production data from a database when the trigger signal is received, wherein the storage device production data comprises process input variables;
- and
- identifying one or more potential root causes of the storage device production failure based in part on an analysis of the process input variables.
A non-transitory machine readable medium comprising instructions which, when executed, direct a computing system to perform operations comprising:
- receiving a trigger signal from a factory quality control unit, the trigger signal generated when a storage device production failure is detected;
- extracting storage device production data from a database when the trigger signal is received, wherein the storage device production data comprises process input variables;
- and
- identifying one or more potential root causes of the storage device production failure based in part on an analysis of the process input variables.
