1. Technical Field
The present disclosure relates to a method for monitoring a burn-in procedure of an electronic device.
2. Description of Related Art
“Burn-in” is a process to detect particular components of electronic devices that would fail as a result of the initial, high-failure rate portion of the bathtub curve of component reliability. The particular components may include CPU, memory, and motherboard, for example. If the burn-in period is made sufficiently long, the electronic devices can then be trusted to be mostly free of further early failures once the burn-in process is complete. However, to monitor the “burn-in” for mass production of electronic devices may be time consuming.
The external storage device 4 stores computerized code including a monitor procedure 40 and a burn-in procedure (not shown). The burn-in procedure is a method that details a process to burn-in for the electronic device 2. The monitor procedure 40 is a method used to monitor the burn-in procedure. The monitor procedure 40 is initially stored in the external storage device 4 and may not be installed in the electronic device 2. After the electronic device 2 is turned off, the monitor procedure 40 stored in the memory 20 may be automatically erased because the memory 20 is a RAM. As a result, an operating system (OS) of the electronic device 2 is not changed during the burn-in procedure.
The host computer 3 copies the monitor procedure 40 from the external storage device 4 to the memory 20 of the electronic device 2. The host computer 3 then activates the monitor procedure 40 stored in the memory 20 and activates the burn-in procedure for the electronic device 2. The monitor procedure 40 stored in the memory 20 determines a state of the burn-in procedure and outputs a monitor result corresponding to the state of the burn-in procedure into the display device 1. The display device 1 displays the monitor result.
The display device 1 displays a first state when the burn-in procedure is normally operative. The display device 1 displays a second state when the burn-in procedure is successfully complete. The display device 1 displays a third state when the burn-in procedure is failed or if the burn-in procedure is not activated. The display device 1 may include a lightning module (not shown) to display the monitor result. In the exemplary embodiment, the lightning module flashes to indicate the first state, lights continuously to indicate the second state, and stays off to indicate the third state.
In block S10, the host computer 3 copies the monitor procedure 40 to the memory 20 and activates the monitor procedure 40.
In block S20, the monitor procedure 40 stored in the memory 20 activates the burn-in procedure for the electronic device 2 and determines the state of the burn-in procedure.
In block S30, the monitor procedure 40 stored in the memory 20 outputs the monitor result corresponding to the state of the burn-in procedure into the display device 1.
In block S200, the monitor procedure 40 stored in the memory 20 tests at least one process of internal operation of the electronic device 2 during a burn-in procedure.
In block S210, the monitor procedure 40 stored in the memory 20 determines whether the at least one process is abnormal. If the at least one process is normal, the block S230 is then implemented.
If the at least one process is abnormal, in block S220, the monitor procedure 40 stored in the memory 20 determines whether the burn-in procedure is finished. If the burn-in procedure is not finished, block S210 is repeated.
In block S230, the monitor procedure 40 stored in the memory 20 generates the monitor result corresponding to the state of the burn-in procedure. If the at least one process is normal, the monitor procedure 40 stored in the memory 20 determines that the burn-in procedure is successfully complete. If the at least one process is abnormal, the monitor procedure 40 stored in the memory 20 determines that the burn-in procedure is failed.
The present disclosure provides a method for automatically monitor a burn-in procedure of an electronic device. The hours of operators for monitoring the burn-in procedure may be saved.
Although certain inventive embodiments of the present disclosure have been specifically described, the present disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the present disclosure without departing from the scope and spirit of the present disclosure.
