Is possible.

FIG. 15 is a perspective view showing an example of the storage medium 200. The storage medium 200 that performs an evaluation test by the evaluation test apparatus 1 according to the present embodiment is a so-called SSD (solid state drive), and is a storage apparatus that uses a semiconductor element memory. As the storage medium 200, for example, a card-type SSD as shown in FIG. 16 is used. The storage medium 200 includes a plate-like connection portion 201 that is inserted into the connection portion 61 included in the connection substrate 60 of the evaluation test apparatus 1. The storage medium 200 can perform input / output with the connection board 60 by PCI Express.

The storage medium 200 is formed such that the length in the direction orthogonal to both the insertion / removal direction and the thickness direction of the connection portion 201 is longer than the width in the insertion / removal direction. That is, the storage medium 200 is formed such that the length of the storage medium 200 in the longitudinal direction of the connection portion 61 of the connection substrate 60 is longer than the width in the insertion / extraction direction. For this reason, when the storage medium 200 is connected to the connection portion 61 of the connection substrate 60 and disposed in the circulation path 33, the air flowing through the storage medium 200 in the circulation path 33 extends in the longitudinal direction of the storage medium 200. Flowing. Further, a bracket 202 is provided on one end side in the longitudinal direction of the storage medium 200 to be fixed to the devices when the storage medium 200 is mounted on the devices such as a personal computer.

The evaluation test apparatus 1 according to the present embodiment has the above-described configuration, and the operation thereof will be described below. When performing the evaluation test of the storage medium 200 using the evaluation test apparatus 1, the main opening / closing door 3 is opened, and the connection portion 61 of the storage medium 200 is connected to the connection portion 61 of the connection substrate 60 disposed in the test chamber 31. Plug in 201 and connect. At that time, the bracket 202 of the storage medium 200 is held by the storage medium holding stay 120 and the stay lock member 121, thereby holding the storage medium 200 in a stable state and preventing the storage medium 200 from being accidentally removed. . Specifically, when the connection portion 201 of the storage medium 200 is inserted into the connection portion 61 of the connection substrate 60, the storage medium 200 is inserted in a direction in which the bracket 202 is positioned on the lower side. When the storage medium 200 is inserted into the connection part 61, the storage medium holding stay 120 is rotated to a state where the movement of the storage medium 200 in the direction of coming out of the connection part 61 can be restricted. The rotation of the storage medium holding stay 120 is restricted. This prevents the storage medium 200 from being disconnected. Note that when the storage medium 200 is pulled out from the connecting portion 61, the stay lock member 121 is operated to release the restriction on the rotation of the storage medium holding stay 120 and then pulled out. Since ten connection boards 60 are provided, the required number of storage media 200 is inserted in the connection portion 61 of the connection board 60 within the range of 1 to 10 in the test chamber 31. Can be arranged.

When the storage medium 200 is placed in the test chamber 31, the main door 3 is closed and the evaluation test is started. When performing an evaluation test, the user of the evaluation test apparatus 1 performs an appropriate test by performing an input operation on the operation panel 21 while visually recognizing the touch panel 22 of the operation panel 21. In the evaluation test, a test signal is transmitted from the test control board 70 to the storage medium 200.

When transmitting a signal from the test control board 70 to the storage medium 200, the signal is transmitted from the test board side connection board 65 inserted into the board connection portion 71 of the test control board 70 to the cable 66, and from the cable 66 to the connection board 60. Is transmitted. The connection board 60 transmits the signal transmitted from the cable 66 to the storage medium 200 from the connection unit 61. Thereby, the signal output from the test control board 70 is transmitted to the storage medium 200.

Further, at the time of the evaluation test of the storage medium 200, power for operating the storage medium 200 is supplied from the power control board 80 connected to the connection board 60. The power control board 80 supplies power for operating the storage medium 200 to the storage medium 200 via the connection board 60 and supplies power to the storage medium 200 based on a signal from the test control board 70. Change. As a result, a test relating to power during operation of the storage medium 200 is also performed.

An example of the evaluation test will be described. In the evaluation test, the storage medium 200 is subjected to a voltage margin test, which is a test for an allowable amount with respect to a change in the voltage during operation of the storage medium 200, and a predetermined load is applied to the storage medium 200. The long run test, which is a test of whether or not the storage medium 200 can continue to operate stably even if the storage medium 200 is continuously operated for a certain period of time, in the same manner as the actual usage environment and usage method before shipping the storage medium 200 An aging test, which is a test for confirming whether the performance and functions are exhibited as specified by operating the system, and appropriately performing recovery when error communication is intentionally performed to the storage medium 200 An error injection test, which is a test of whether or not the storage medium 200 can transmit / receive data per second A performance measurement or the like is performed.

These evaluation tests can be performed by connecting a personal computer to the test control board 70 through a LAN (Local Area Network) cable. In addition, the personal computer connected to the touch panel 22 and the test control board 70 of the operation panel 21 can appropriately switch and display information on the state of the evaluation test apparatus 1 and the storage medium 200 being tested. For this reason, during the evaluation test, the test can be performed while confirming necessary information of the evaluation test apparatus 1 and the storage medium 200. For example, the touch panel 22 can display the temperature of the evaluation test apparatus 1 and the ON / OFF state of the voltage output to the storage medium 200. Further, the personal computer can display the voltage and current consumption during operation of the storage medium 200 and the temperature of each storage medium 200. Various data at the time of the evaluation test can be stored in a personal computer and can be taken out later.

Further, since heat is generated when the storage medium 200 is in operation, the air in the circulation path 33 is heated by the heater 50 while the air in the circulation path 33 is circulated by the intake fan 41 and the exhaust fan 42 during the evaluation test. The operation is performed while opening and closing the exhaust opening / closing door 45 and the intake opening / closing door 46. Heating by the heater 50 and opening / closing control of the exhaust opening / closing door 45 and the intake opening / closing door 46 are performed by the thermostatic chamber control board 100.

Specifically, the thermostatic chamber control board 100 acquires the temperature in the circulation path 33 by acquiring the detection result of the temperature sensor 51 disposed in the circulation path 33, and the acquired temperature and the target temperature. By comparing the above, the heater 50 is heated and the exhaust port motor 47 and the intake port motor 48 are operated.

For example, when the temperature in the circulation path 33 detected by the temperature sensor 51 is lower than the target temperature, the exhaust opening / closing door 45 and the intake opening / closing door 46 are closed by the exhaust opening motor 47 and the intake opening motor 48. Meanwhile, the heater 50 is heated. Thereby, the air in the circulation path 33 is heated with the circulation path 33 sealed. Since the air in the circulation path 33 is circulated by the intake fan 41 and the exhaust fan 42, the entire air flowing in the circulation path 33 is heated by heating the heater 50 and heating the air around the heater 50. Heated, the temperature of the air in the entire circulation path 33 rises.

Conversely, when the temperature in the circulation path 33 detected by the temperature sensor 51 is higher than the target temperature, the degree of heating of the heater 50 is reduced or the heating of the heater 50 is stopped. Thereby, the temperature in the circulation path 33 is lowered. Even if the heating of the heater 50 is stopped, if the temperature in the circulation path 33 is higher than the target temperature, the temperature is increased by operating the exhaust port motor 47 and opening the exhaust port opening / closing door 45. The air in the circulation path 33 is discharged from the exhaust port 43, or the intake port motor 48 is operated to open the intake port opening / closing door 46, so that the temperature is lower than that in the circulation path 33. Air is taken into the circulation path 33 from the intake port 44. Thereby, the temperature of the air in the circulation path 33 falls, and it can approach the target temperature.

When the temperature in the circulation path 33 detected by the temperature sensor 51 is higher than the target temperature, when the intake port opening / closing door 46 is opened, air outside the circulation path 33 flows from the intake port 44. Although the temperature of the air in the circulation path 33 decreases by entering the circulation path 33, the intake port 44 is disposed on the upstream side of the heater 50 in the flow direction of the air flowing through the circulation path 33. For this reason, the air that has entered through the air inlet 44 does not flow directly into the temperature sensor 51 but flows after the air that has entered through the air inlet 44 is mixed with the air in the circulation path 33. The sensor 51 can appropriately detect the air in the circulation path 33 even when the intake opening / closing door 46 is opened.

Further, when the temperature detected by the temperature sensor 51 becomes higher than a predetermined threshold value, the thermostatic chamber control board 100 operates the solenoid 18 of the lock mechanism 15 to cause the protrusion 17 to enter the recess 16. As a result, the main door 3 is locked, and the main door 3 cannot be opened when the test chamber 31 is at a high temperature. The lock mechanism 15 that locks the main door 3 can be manually unlocked when the temperature detected by the temperature sensor 51 becomes low.

A plurality of blowing ports 55 corresponding to the plurality of connection boards 60 are provided on the upstream side of the connection board 60 in the flow direction of the air flowing through the circulation path 33. Air is blown to the connection substrate 60 from the blowing port 55 corresponding to 60. For this reason, since air is blown from the corresponding blowing port 55 to the storage medium 200 connected to the connection portion 61 of each connection board 60, the air flowing through the test chamber 31 of the circulation path 33 flows. Flows evenly with respect to the plurality of storage media 200 arranged in the test chamber 31. Thereby, when changing the temperature in the circulation path 33 to arbitrary temperature, the temperature around the several storage medium 200 arrange | positioned in the test chamber 31 can be changed equally.

Furthermore, since the connection board 60 is disposed in the longitudinal direction of the connection portion 61 in the direction in which air flows, the flow direction of the air flowing through the test chamber 31 is relative to the storage medium 200 connected to the connection portion 61. Also flows along the longitudinal direction of the storage medium 200. Here, in a device such as a personal computer in which the storage medium 200 is used, a cooling fan is provided. However, the flow direction of air by the fan of these devices is normally set to the storage medium 200. It often flows in the longitudinal direction of the storage medium 200. For this reason, when the flow direction of the air flowing through the test chamber 31 flows in a direction along the longitudinal direction of the storage medium 200, the storage medium 200 flows in a state close to a state in which the storage medium 200 is actually used. In other words, the evaluation test of the storage medium 200 in the evaluation test apparatus 1 is performed by reproducing an environment close to the environment when the storage medium 200 is actually used.

While the temperature in the circulation path 33 is close to the target temperature while the temperature sensor 51 detects the temperature in the circulation path 33 as described above, the heater 50, the exhaust motor 47, and the intake motor 48 are in contact with each other. Feedback control. Since the evaluation test apparatus 1 can perform the feedback control in this way, the temperature in the circulation path 33 can be set to an arbitrary target temperature. Therefore, in the evaluation test of the storage medium 200, a high temperature test is also performed. Can do. That is, an arbitrary temperature for performing a high temperature test on the storage medium 200 is set as a target temperature at the time of the evaluation test, and the storage medium 200 is operated with the temperature in the circulation path 33 set to the target temperature. Thereby, the storage medium 200 can be evaluated during operation at a high temperature.

Furthermore, a temperature margin test in a high-load access state or a high-load access state can be performed by increasing the temperature or changing the voltage while reading from or writing to the storage medium 200 at a high speed. Perform a voltage margin test.

Here, the test control board 70 that transmits the signal for the evaluation test to the storage medium 200 at the time of the evaluation test of the storage medium 200 is disposed at a position different from the thermostat 30, that is, the test control board 70. Is disposed outside the circulation path 33. If the temperature of the test control board 70 becomes too high, thermal runaway occurs, and it may not be possible to appropriately perform operations such as arithmetic processing, and an evaluation test may not be performed. Is arranged outside the circulation path 33, so that even when the temperature of the circulation path 33 is increased, the test control board 70 is not affected by the heat of the circulation path 33. For this reason, even when a high temperature test is performed, the test control board 70 can operate stably, and an appropriate evaluation test can be performed.

In the evaluation test by the evaluation test apparatus 1, the air circulating through the circulation path 33 flows evenly to the plurality of storage media 200 through the blowing ports 55, and in the direction along the longitudinal direction of the storage media 200. Since the air flows, an environment close to the actual use environment of the storage medium 200 is reproduced, but the evaluation test apparatus 1 according to the present embodiment further stores the wind speed of the air flowing through the circulation path 33. It is possible to approach the wind speed when the medium 200 is actually used.

Specifically, the operating speed of the intake fan 41 and the exhaust fan 42 is adjusted by performing an input operation on the operation panel 21. With respect to the intake fan 41 and the exhaust fan 42, values input to the operation panel 21 are transmitted to the fan control board 101 through the thermostatic bath control board 100 and controlled by the fan control board 101. The fan control board 101 changes the operating speed of the intake fan 41 and the exhaust fan 42 by, for example, duty control, and the wind speed at the position of the storage medium 200 is substantially equal to the wind speed in the device in which the storage medium 200 is actually used. Use the same wind speed. Thereby, the environment at the time of the evaluation test of the storage medium 200 can be brought closer to the environment at the time of actual use of the storage medium 200. Further, by adjusting the operating speeds of the intake fan 41 and the exhaust fan 42, it is possible to make the wind speed uniform while suppressing variations in the wind flowing in the vicinity of the storage medium 200, and the evaluation test is performed in a stable environment. be able to.

Also, as the evaluation test, an evaluation test can be performed when the power supplied to the storage medium 200 is suddenly cut off. In the evaluation test when the power is cut off, the power supplied from the power control board 80 to the storage medium 200 via the connection board 60 is cut off. At this time, since the power control board 80 includes the discharge circuit 81, the power supplied from the storage medium 200 can be cut off, and the power stored in the storage medium 200 can be discharged by the discharge circuit 81. If the power supplied to the storage medium 200 is simply cut off, the power stored in the storage medium 200 is slowly discharged, so that the evaluation test of the storage medium 200 at the time of power cut takes time. Then, since the discharge is performed in a short time by the discharge circuit 81, the evaluation test of the storage medium 200 when the power is cut off can be performed in a short time.

Further, the evaluation test apparatus 1 according to the present embodiment can perform an evaluation test by arbitrarily generating a pattern for writing to and reading from the storage medium 200 by connecting a personal computer to the test control board 70 via a LAN cable. it can.

Further, the auxiliary cable terminal 111 of the auxiliary cable 110 arranged in the test chamber 31 can be connected to the storage medium 200 arranged in the test chamber 31 as necessary. Since the other end side of the auxiliary cable 110 is connected to the auxiliary cable connection terminal 26 of the operation panel 21, when the auxiliary cable terminal 111 is connected to the storage medium 200, the auxiliary door 110 is closed with the main opening / closing door 3 closed. Direct communication can be performed with the storage medium 200 from the outside via the cable connection terminal 26.

In the evaluation test apparatus 1 for the storage medium 200 according to the above embodiment, the connection board 60 having the connection part 61 to which the storage medium 200 is connected is arranged in the circulation path 33 in the direction in which air flows in the longitudinal direction of the connection part 61. It is installed. Thereby, when the air in the circulation path 33 is circulated by the intake fan 41 and the exhaust fan 42, the air flowing through the circulation path 33 does not flow in the direction in which the storage media 200 are arranged, but instead of the connection portion 61. Can flow around the individual storage media 200 along the longitudinal direction of the storage media 200 connected to the. For this reason, for example, when the temperature of the air flowing through the circulation path 33 is increased by the heater 50, the ambient temperature of each storage medium 200 can be uniformly set to an arbitrary temperature. As a result, each of the plurality of storage media 200 can be tested in a state along the actual temperature environment.

Further, by arranging the intake fan 41 above the test chamber 31 and the exhaust fan 42 below the test chamber 31, the thermostat 30 can be downsized in the horizontal direction, and the evaluation test apparatus 1 as a whole. Can be slimmed. As a result, the installation area when installing the evaluation test apparatus 1 can be reduced.

In addition, since the connection substrate 60 is arranged in such a direction that the insertion / extraction direction of the storage medium 200 inserted / removed into / from the connection portion 61 is in the range of 10 ° to 30 ° upward from the horizontal direction, On the other hand, when inserting / removing the storage medium 200, it can carry out more reliably. That is, when inserting / removing the storage medium 200 in the vertical direction, since the visibility is poor, there is a possibility that the insertion / extraction may fail, but visibility can be ensured by inserting / removing at an angle close to the horizontal direction, Errors during insertion and removal can be avoided. As a result, workability during the evaluation test can be improved, and the evaluation test of the storage medium 200 can be performed more reliably and at high speed.

Further, in order to adjust the operating speed of the intake fan 41 and the exhaust fan 42 to adjust the wind speed of the air flowing through the circulation path 33, the environment during the evaluation test of the storage medium 200 is the same as when the storage medium 200 is actually used. It can be closer to the environment. As a result, it is possible to reduce an error in the evaluation result due to an erroneous calculation between the environment during actual use of the storage medium 200 and the environment during the evaluation test, and a more accurate evaluation test can be performed.

Further, since air is blown from the blowing ports 55 corresponding to the connection substrates 60 to the plurality of storage media 200 connected to the plurality of connection substrates 60, it is possible to suppress the deviation of the air flow, Variations in the temperature environment for each storage medium 200 can be suppressed. As a result, it is possible to reduce the error of the evaluation result due to the temperature variation for each position of the storage medium 200 in the test chamber 31, and to perform a more accurate evaluation test.

Further, the connection board 60 is attached to the wall portion 38 that separates the inside of the circulation path 33 and the non-constant temperature part 37, and the cable 66 connected to the connection board 60 is drawn out from the non-constant temperature part 37. Even when the internal temperature is raised, heat transfer to the cable 66 can be suppressed. Thereby, it can suppress that the cable 66 becomes high temperature, and can suppress that the heat of the cable 66 is transmitted to the test control board 70 and the temperature of the test control board 70 becomes too high. As a result, thermal runaway of the test control board 70 can be suppressed.

The circulation path 33 is provided with an exhaust port 43 having an exhaust port opening / closing door 45 and an intake port 44 having an intake port opening / closing door 46, so that the exhaust port opening / closing door 45 and the intake port opening / closing door 46 are opened and closed. Thus, the temperature in the circulation path 33 can be more reliably set to a desired temperature. As a result, the temperature accuracy during the evaluation test of the storage medium 200 can be increased, and a more accurate evaluation test can be performed.

In addition, since the intake port 44 is disposed on the upstream side of the heater 50 in the flow direction of the air flowing through the circulation path 33, when the intake port opening / closing door 46 is opened, the air that has entered from the intake port 44 is circulated. Air in a state of being mixed with the air in the path 33 can be passed through the temperature sensor 51. As a result, when the air inlet opening / closing door 46 is opened, the temperature of the air entering through the air inlet 44 is directly detected by the temperature sensor 51, and the temperature of the circulation path 33 cannot be appropriately controlled. Can be prevented. As a result, the temperature accuracy during the evaluation test of the storage medium 200 can be increased, and a more accurate evaluation test can be performed.

In addition, since the power control board 80 that controls the power supplied to the storage medium 200 is provided with a discharge circuit 81 that discharges the storage medium 200, the power supplied to the storage medium 200 is cut off. In doing so, the storage medium 200 can be shut off stably and in a short time without imposing a burden. As a result, the power on / off test can be performed more reliably at high speed. As a result, a highly accurate evaluation test can be performed at a higher speed.

Further, since the test control board 70 is disposed outside the circulation path 33 and is connected to the connection board 60 via the test board side connection board 65 and the cable 66, the heat of the circulation path 33 is transferred to the test control board. The signal can be transmitted from the test control board 70 to the storage medium 200 with a waveform having an appropriate size while suppressing the transmission to the network 70. Thereby, it is possible to appropriately transmit a signal to the storage medium 200 and perform the evaluation test while suppressing thermal runaway of the test control board 70 during the evaluation test. As a result, a highly accurate evaluation test can be performed more reliably.

Further, although a plurality of connection boards 60 are provided, the plurality of cables 66 that connect the plurality of connection boards 60 and the test control board 70 have the same length. It can suppress that the quality of the signal transmitted differs between connection boards 60. As a result, it is possible to suppress variations in signals when performing an evaluation test of a plurality of storage media 200, and it is possible to more reliably perform the evaluation test with high accuracy.

In addition, when the temperature detected by the temperature sensor 51 becomes higher than a predetermined threshold, the lock mechanism 15 locks the opening / closing of the main door 3, so that the main door 3 can be opened while the test chamber 31 is at a high temperature. Can be suppressed. As a result, safety can be improved during the evaluation test.
