Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system configurations, techniques, etc. in order to provide a thorough understanding of the disclosed embodiments. However, it will be apparent to one skilled in the art that the present disclosure may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present disclosure with unnecessary detail.
Referring to fig. 1, a flowchart of a method for automatically recording usage time of an burn-in board according to an embodiment of the disclosure is shown. The method for automatically recording the service time of the burn-in board may be performed by an electronic device mounted on the burn-in board, including but not limited to a microcomputer such as a single chip or an integrated chip.
As shown in fig. 1, the method for automatically recording the service time of the burn-in board includes:
S101, detecting whether an aging board is in a power-on state;
S102, when the aging plate is in a power-on state, acquiring a temperature detection value of the aging plate in real time;
S103, judging whether the temperature detection value is equal to or greater than a preset temperature threshold value;
S104, if yes, starting a timer to start timing, wherein the timer is preset with a timing period;
And S105, when the timing period expires, writing the time corresponding to the timing period into the memory.
The burn-in board is a circuit board for bearing chips to be tested, and the burn-in board and the chips are placed in a high-low temperature box together to realize burn-in test of the chips.
The method for automatically recording the service time of the aging plate is characterized in that whether the aging plate is in a power-on state or not is detected, and when the aging plate is in the power-on state, a temperature detection value of the aging plate is obtained in real time; judging whether the temperature detection value is equal to or greater than a preset temperature threshold value; if yes, starting a timer to start timing, wherein the timer is preset with a timing period; when the timing period expires, the time corresponding to the timing period is written into the memory, so that the service time of the aging plate is automatically recorded, the accuracy of the recorded time is ensured, and meanwhile, the service life of the aging plate is considered to be related to the temperature, and the recorded time is related to the working temperature of the aging plate, so that the service time of the aging plate is recorded more rigorously and scientifically.
In some embodiments, after detecting whether the burn-in board is in the power-up state in the step S101, the method further includes: when the burn-in board is in a non-powered state, the timer is controlled to stop counting, and the recorded time is written into the memory.
The unpowered state includes the burn-in board being in a powered-down state. In this embodiment, the timer is preferably a timer with a memory function, and if the timer is powered down before the timing period is not full, the time recorded before the power down can be written into the memory when the timer resumes to be powered up, so as to prevent the occurrence of the loss of time data of the timing period which is not full due to the power down. Specifically, the current technical means for realizing the memory function of the timer is very many, for example, the memory function is preset in the timer in some single-chip microcomputer, or a super capacitor can be used as a standby power supply, the count value in the timer is written into the register by utilizing the power of the super capacitor at the time of power failure, and the count value in the register is written into the timer when the power of the timer is restored, so that the timer is restored to the timing state before power failure. It will be appreciated that embodiments of the present disclosure are not limited in the implementation of the memory function of the timer.
Wherein, because the service life of the ageing plate is related to the temperature, the service lives of the ageing plates produced by different manufacturers are not completely consistent. Therefore, when the manufacturer leaves the factory, the working temperature range of the ageing board is generally marked, and the service life of the ageing board in different working temperature ranges is generally marked. For example, assuming an burn-in board a, factory parameters given by the manufacturer include: the service life of the aging plate at the temperature T1 is S1; the service life of the aging plate at the temperature T2 is S2; the service life of the burn-in board at the temperature T3 is S3. Here, the temperatures T1, T2, and T3 may be temperature values or temperature intervals, which are not limited in the embodiment of the present disclosure.
In some embodiments, the method for automatically recording the usage time of the burn-in board further includes: the method comprises the steps of reading factory parameters of an aging board, wherein the factory parameters comprise at least one working temperature and service life time corresponding to each working temperature; based on at least one operating temperature, a time record document and a total operating time document are generated in memory in a one-to-one correspondence to each operating temperature.
Specifically, the preset temperature threshold may be a minimum temperature value in at least one working temperature provided by the manufacturer parameter, or may be another temperature value lower than the minimum temperature value, which is not limited by the embodiment of the present disclosure.
The manufacturer parameters may be written to the chip on the burn-in board at the time of shipping the burn-in board, or may be labeled on the burn-in board. For the above example, if the manufacturer parameters include 3 operating temperatures T1, T2 and T3, and the service lives of T1, T2 and T3 are S1, S2 and S3, then the time record document D1 corresponding to the operating temperature T1, the time record document D2 corresponding to the operating temperature T2 and the time record document D3 corresponding to the operating temperature T3 may be generated in the memory, and a total operating time document DZ may be generated. Therefore, the service time of the aging board at different working temperatures can be recorded in the corresponding time record documents, and the association record of the service time and the working temperature of the aging board is realized.
In one embodiment, in the step S105, writing the time corresponding to the timing period into the memory includes: determining an average temperature detection value of the timing cycle device based on the timing cycle start and the temperature detection value at expiration; calculating the difference value of each working temperature in the factory parameters of the average temperature detection value and the aging board, and determining the working temperature corresponding to the minimum difference value as the target working temperature corresponding to the timing period; and writing the time corresponding to the timing period into a time record document and a total working time document corresponding to the target working temperature.
The timing period can be set according to practical situations, for example, the timing period can be 10sec, 20sec, 30sec, 40sec, 50sec or 60sec; and may be 2min, 4min, 6min, 8min, 10min, etc., which is not limited by the embodiments of the present disclosure.
Since the time period is a time period, the number of the obtained temperature detection values is generally a plurality of in this time period, the average temperature detection value in this time period can be calculated by using the two temperature detection values obtained from the beginning and the end in the time period of the time period, or the average temperature detection value in this time period can be calculated by using all the obtained temperature detection values in the whole time period of the time period, and the average temperature detection value is compared with the working temperature in the manufacturer parameters to determine which working temperature the temperature of the aging board is in the time period of the time period.
For example, assuming that the manufacturer parameters provide T1, T2, and T3 at 30 ℃, 60 ℃, and 120 ℃ respectively, and the time period is 10min, if a total of 100 temperature detection values are obtained in a certain time period, the average temperature detection value T agv may be calculated by using the 1 st obtained temperature detection value and the 100 th obtained temperature detection value, or the average temperature detection value T agv may also be calculated by using the 100 th obtained temperature detection values, and assuming that the average temperature detection value T agv is 43 ℃, the absolute values of the differences are obtained by calculating the average temperature detection values T agv and T1, T2, and T3 respectively, and the differences are 13, 17, and 77 respectively, wherein 13 is the minimum difference, and the corresponding operating temperature is T1, that is, 30 ℃, so the time period (10 min) corresponding to the time period is written into the time record document corresponding to 30 ℃, and the total operating time document.
In another embodiment, in step S105, writing the time corresponding to the timing period into the memory further includes: generating a change relation curve of the temperature detection value and time in the time of the timing period based on the temperature detection value in the period of the timing period; and writing a change relation curve of the temperature detection value and time into a time record document corresponding to the target working temperature.
According to the embodiment, the change relation curve of the temperature detection value and time in the time period where the timing period is located is increased, so that the change relation of the working temperature of the aging board along with time can be obtained, the change relation curve corresponding to each timing period can be displayed according to the sequence of the recorded time in the later period, the temperature change relation except the use time of the aging board is obtained, recorded content is enriched, and more reference data are provided for later-period aging board research.
In addition, in still another embodiment, in the method for automatically recording the usage time of the burn-in board, when writing the time corresponding to the timing period into the total working time document, the written time is accumulated to obtain a time accumulated value; judging whether the time accumulated value is equal to or greater than a preset time threshold, wherein the factory parameters comprise the preset time threshold; if yes, the alarm arranged on the aging board is controlled to send out an alarm prompt, or prompt information is sent to an external terminal connected with the aging board.
Although the burn-in board provides a service life of the burn-in board at different working temperatures when shipped, in actual use, the burn-in board often does not always work at a certain working temperature, and therefore, the manufacturer generally provides a preset time threshold as the total service life of the burn-in board. Of course, this preset time threshold may be longer than the service life of some operating temperatures, or may be shorter than the service life of some operating temperatures, which is not limiting in accordance with the disclosed embodiments.
Specifically, for the total working time document, the written time is accumulated, so that the total use time of the aging board under the condition of reaching the temperature threshold value can be obtained, when new time is written into the total working time document, the time is accumulated, the time accumulated value is obtained and then is compared with the time threshold value, whether the use time of the aging board reaches the preset time threshold value is judged, and when the time accumulated value is equal to or greater than the preset time threshold value, an alarm prompt is actively sent out, the aging board is replaced in time, and the unpredictable problems caused by chip test by using the aging board for a long time are avoided.
The alarm can be a buzzer, a flash lamp or a power-off switch, and the like, for example, the alarm is a buzzer, and when the accumulated time value is equal to or greater than the time threshold value, the buzzer is controlled to give out alarm sound, so that the alarm prompt function is realized. It will be appreciated that the disclosed embodiments are not limited in terms of the type of alarm.
In some embodiments, the method for automatically recording the usage time of the burn-in board further includes: in the case that the burn-in board is connected with the external terminal, the burn-in board transmits the time information recorded in the memory to the external terminal; or under the condition that the aging board receives a reading instruction sent by the external terminal, the aging board sends the time information recorded in the memory to the external terminal; wherein the time information includes at least one of the following information: the time recorded by the timer, the temperature detection value during the timing period and the change relation curve of the temperature detection value and time during the timing period.
The external terminal may be hardware or software. When the external terminal is hardware, the external terminal can be electronic equipment such as a smart phone, a desktop computer or a tablet computer; when the external terminal is software, it may be an application installed on the aforementioned electronic device, for example, burn-in board data analysis software installed on a desktop computer.
The connection between the burn-in board and the external terminal comprises wired connection and wireless connection, wherein the wired connection comprises the connection between the burn-in board and the external terminal through a data line, for example, the connection is performed through a USB data line; the wireless connection includes a short-distance wireless communication connection such as WIFI, bluetooth, and infrared, for example, the wired connection includes that the burn-in board and the external terminal are in communication connection through bluetooth.
In the case that the burn-in board receives a read command sent by the external terminal, the external terminal is preferably an application program installed on a smart phone or a computer, and in the case that the burn-in board is connected to the external terminal, the user can send the read command on the application program to request the electronic device on the burn-in board to send recorded time information for implementing the method for automatically recording the usage time of the burn-in board.
Next, in one embodiment, in the above method of automatically recording the usage time of the burn-in board, when the time information recorded in the memory is updated, the updated time information is transmitted to the external terminal. This enables the external terminal to obtain the latest time information on the usage of the burn-in board in time.
Referring to fig. 2, a flowchart of another method for automatically recording usage time of an burn-in board according to an embodiment of the disclosure is shown. As shown in fig. 2, the method for automatically recording the service time of the burn-in board includes:
s210, detecting whether the burn-in board is in a power-on state;
S220, when the aging plate is in a power-on state, acquiring a temperature detection value of the aging plate in real time;
s221, judging whether the temperature detection value is equal to or greater than a preset temperature threshold value;
S222, if not, returning to the step S210;
s223, if yes, starting a timer to start timing, wherein the timer is preset with a timing period;
s224, when the timing period expires, writing the time corresponding to the timing period into a memory;
and S230, when the burn-in board is in a non-power-on state, controlling the timer to stop counting, and writing the recorded time into the memory.
The method for automatically recording the service time of the aging board provided by the embodiment is characterized in that whether the aging board is in a power-on state or not is detected, and when the aging board is in the power-on state, a temperature detection value of the aging board is obtained in real time; judging whether the temperature detection value is equal to or greater than a preset temperature threshold value; if yes, starting a timer to start timing, wherein the timer is preset with a timing period; when the timing period expires, the time corresponding to the timing period is written into the memory, so that the service time of the aging plate is automatically recorded, the accuracy of the recorded time is ensured, and meanwhile, the service life of the aging plate is considered to be related to the temperature, and the recorded time is related to the working temperature of the aging plate, so that the service time of the aging plate is recorded more rigorously and scientifically.
