Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Some embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
According to the research and development requirements, in the process of debugging a chip by using a board inspection machine, an electric signal on an aging board is often required to be inspected by using tools such as a universal meter, an oscilloscope and the like, wherein the circuit board after aging treatment is called the aging board. The electrical signals to be measured on the burn-in board may be distributed on the front and back sides of the burn-in board, but with current burn-in machines, the burn-in board can only be inserted into the burn-in machine in the front side, and it is difficult for engineers to measure the electrical signals on the back side of the burn-in board. In view of the above, the present invention provides an aging machine for alleviating the above-mentioned problems.
Example 1
Fig. 1 is a functional block diagram of an aging machine according to an embodiment of the present invention, as shown in fig. 1, the aging machine includes: test host 100, drive board 200 and interface board 300; the interface board 300 includes: a first physical interface 301, a signal switching component 302, and a second physical interface 303.
The test host 100 is connected with the driving board 200 and the interface board 300, respectively; the driving board 200 is also connected with the interface board 300; the signal switching component 302 is connected with the first physical interface 301 and the second physical interface 303 respectively; the second physical interface 303 is provided with an burn-in board front insertion detection end and a burn-in board back insertion detection end.
The first physical interface 301 is for connection with the drive board 200.
The second physical interface 303 is for connection with the burn-in board 400.
The signal switching component 302 is configured to support a forward mapping relationship or a backward mapping relationship between the connection terminal of the first physical interface 301 and the connection terminal of the second physical interface 303.
The driving board 200 is configured to output a predetermined test signal to the first physical interface 301 under the configuration of the test host 100.
When the burn-in board 400 is inserted into the second physical interface 303 and the test host 100 determines that the current mapping relationship of the signal switching component 302 does not match the insertion direction of the burn-in board 400 based on feedback from the front insertion detection end of the burn-in board and the rear insertion detection end of the burn-in board, the test host 100 sends a mapping relationship switching instruction to the signal switching component 302 to conduct a signal transmission line between the first physical interface 301 and the burn-in board 400, and then drives the burn-in board 400 to enter a preset test mode by using a preset test signal.
In the embodiment of the present invention, the test host 100 may be used to store various preset test parameters of the burn-in machine and control the driving board 200 and the burn-in board 400. Based on the above description of the structure of the burn-in device and the functions of the modules, in order to facilitate the measurement of the electrical signals on the back of the burn-in board 400 by the engineer, the structural design of the interface board 300 of the burn-in device according to the embodiment of the present invention is improved, first, the interface board 300 includes a signal switching component 302 and two physical interfaces, a first physical interface 301 is used to establish a physical connection with the driving board 200, a second physical interface 303 is used to establish a physical connection with the burn-in board 400, and the second physical interface 303 supports the front-up insertion (front insertion) and the back-up insertion (back insertion) of the burn-in board 400, so that, in order to enable the burn-in device to support the front-back insertion function of the burn-in board 400, not only the structure of the second physical interface 303 needs to be improved, but also the correspondence of the connection terminals needs to be considered.
Fig. 2 is a schematic diagram of an embodiment of an aging board 400 inserted into an interface board 300, where when the aging board 400 is inserted and inserted in the opposite direction, the connection relationship between the connection terminals on the aging board 400 and the connection terminals on the second physical interface 303 is completely opposite, so in order to establish a correct signal path with the driving board 200 when the aging board 400 is inserted in the opposite direction, a signal switching component 302 is further required to be disposed on the interface board 300, and the signal switching component 302 is capable of supporting a forward-inserting mapping relationship or a backward-inserting mapping relationship between the connection terminals of the first physical interface 301 and the connection terminals of the second physical interface 303. The embodiment of the present invention does not specifically limit the model of the signal switching component 302, and may use an integrated chip or a separate component, so long as the above two mapping relationships can be supported.
Alternatively, the default mapping relationship of the signal switching component 302 may be selected to be a forward mapping relationship, that is, in a default state, the signal switching component 302 establishes a corresponding connection relationship between the connection terminal on the second physical interface 303 and the connection terminal on the first physical interface 301 according to the situation that the burn-in board 400 is being inserted. If the burn-in board 400 is plugged in reversely, the connection relationship between the burn-in board 400 and the second physical interface 303 is completely opposite to the forward plugging condition, and at this time, only the control signal switching component 302 needs to establish a corresponding connection relationship (back-plugging mapping relationship) between the connection terminal on the second physical interface 303 and the connection terminal on the first physical interface 301 according to the reverse plugging condition of the burn-in board 400, so that the connection terminal of the burn-in board 400 and the connection terminal of the first physical interface 301 can be correspondingly connected to ensure the accuracy of the signal transmission path.
In the embodiment of the present invention, in order to enable the burn-in apparatus to identify the insertion direction of the burn-in board 400, an burn-in board front insertion detection end and a burn-in board back insertion detection end are disposed on the second physical interface 303 of the interface board 300, after the burn-in board 400 is inserted into the second physical interface 303, the test host 100 detects the signal states of the burn-in board front insertion detection end and the burn-in board back insertion detection end to determine the insertion direction of the burn-in board 400, and further determines whether the current mapping relationship of the signal switching component 302 matches the insertion direction of the burn-in board 400, and if not, the test host 100 sends a mapping relationship switching instruction to the signal switching component 302 to switch the mapping relationship between the connection terminals of the first physical interface 301 and the second physical interface 303, thereby correctly establishing the signal transmission path between the burn-in board 400 and the first physical interface 301. At this time, the test host 100 configures the working state of the driving board 200 to control the driving board 200 to output a preset test signal to the first physical interface 301, and then transmits the preset test signal to the burn-in board 400 through the interface board 300, so as to drive the burn-in board 400 to enter a preset test mode.
Based on the above description of the burn-in apparatus, the burn-in apparatus according to the present invention can support the front-up insertion or the back-up insertion of the burn-in board 400 through the circuit structure of the interface board 300, which greatly facilitates the measurement of the back electrical signals on the burn-in board 400 by engineers.
In an alternative implementation, the signal switching component 302 in the embodiment of the present invention includes: a switch array including a plurality of electronic selection switches.
In the case where the signal switching component 302 employs a switch array, the switch array and the first physical interface 301 and the second physical interface 303 may select any one of the following two wiring manners:
mode one: each connecting terminal in the second physical interface 303 is connected with the first contact of each electronic selection switch in a one-to-one correspondence manner; the order of connection of the second contacts of the plurality of electronic selection switches with the terminals in the first physical interface 301 is reversed and the order of connection of the third contacts of the plurality of electronic selection switches with the terminals in the first physical interface 301 is reversed.
Mode two: each connecting terminal in the first physical interface 301 is connected with the first contact of each electronic selection switch in a one-to-one correspondence manner; the order of connection of the second contact of the plurality of electronic selection switches with the connection terminal in the second physical interface 303 is reversed from the order of connection of the third contact of the plurality of electronic selection switches with the connection terminal in the second physical interface 303.
For the sake of understanding, in the following, an example of the above manner is illustrated, fig. 3 is a schematic diagram of a connection relationship between a connection terminal of the first physical interface 301 and a connection terminal of the second physical interface 303 and an electronic selection switch, where it is assumed that the first physical interface 301 and the second physical interface 303 each have 5 connection terminals: terminal 1 to terminal 5, then 5 electronic selection switches are also required in the switch array: switch 1-switch 5, and it is possible to provide that the first contact of switch 1 (the contact located in the middle) is connected to the connection terminal 1 of the second physical interface 303, the first contact of switch 2 is connected to the connection terminal 2 of the second physical interface 303, and so on, the first contact of switch 5 is connected to the connection terminal 5 of the second physical interface 303; meanwhile, a second contact of the switch 1 is connected with the wiring terminal 1 of the first physical interface 301, a second contact of the switch 2 is connected with the wiring terminal 2 of the first physical interface 301, and the like, and a second contact of the switch 5 is connected with the wiring terminal 5 of the first physical interface 301; in order to support the reverse plug-in situation of the burn-in board 400, it is also necessary to provide that the third contact of the switch 1 is connected to the connection terminal 5 of the first physical interface 301, that the third contact of the switch 2 is connected to the connection terminal 4 of the first physical interface 301, and so on, that the third contact of the switch 5 is connected to the connection terminal 1 of the first physical interface 301. That is, the order of connection of the second contacts of the plurality of electronic selection switches with the terminals in the first physical interface 301 is reversed from the order of connection of the third contacts of the plurality of electronic selection switches with the terminals in the first physical interface 301. The above description of the number of terminals in each port and the order of connection of the stationary contacts to the terminals is provided for ease of understanding.
When the switch array is used to switch the mapping relationship between the terminals in the first physical interface 301 and the second physical interface 303, the test host 100 only needs to uniformly adjust the action direction of the first contact of the electronic selection switch.
In an alternative embodiment, in the case where the number of connection terminals in the second physical interface 303 is greater than the number of connection terminals of the burn-in board 400, the burn-in board front insertion detection end or the burn-in board back insertion detection end is a free terminal on the second physical interface 303.
Specifically, when the front insertion detection end of the burn-in board and the rear insertion detection end of the burn-in board are selected, the setting may be performed according to the actual conditions of the burn-in board 400 and the second physical interface 303, and if the number of the connection terminals in the second physical interface 303 is greater than the number of the connection terminals of the burn-in board 400, the front insertion detection end of the burn-in board or the rear insertion detection end of the burn-in board may be set as the free terminal on the second physical interface 303. The idle terminals may be terminals on the second physical interface 303 that do not establish a connection with the connection terminals of the burn-in board 400 when the burn-in board 400 is inserted in the forward direction or inserted in the reverse direction. For example, if the second physical interface 303 has 10 terminals 1-10 and the burn-in board 400 has only 6 terminals, any of the remaining 4 terminals in the second physical interface 303 may be used as a front insertion detection terminal or a back insertion detection terminal of the burn-in board. In general, the idle terminal in the forward state is a signal terminal in the reverse state, and therefore, if one of the front insertion detection terminal and the burn-in board rear insertion detection terminal is configured as the idle terminal in the forward state, the other insertion detection terminal should be set as the signal terminal.
Therefore, when the burn-in board 400 is inserted, the test host 100 may determine the insertion direction of the burn-in board 400 according to the impedance change conditions of the front insertion detection end and the back insertion detection end of the burn-in board, for example, if the impedance of the idle terminal in the forward insertion state is not changed after the burn-in board 400 is inserted into the second physical interface 303, and the signal terminal that should occupy in the forward insertion state is connected with the connection terminal of the burn-in board 400, so that the impedance will be changed, then the test host 100 determines that the burn-in board 400 is forward inserted at this time; otherwise, if the impedance of the idle terminal in the reverse-plug state is unchanged, and the impedance of the signal terminal to be occupied in the reverse-plug state is changed, the test host 100 determines that the burn-in board 400 is in the reverse-plug state.
In an alternative embodiment, whether or not the number of the connection terminals in the second physical interface 303 is greater than the number of the connection terminals of the burn-in board 400, the burn-in board front insertion detection terminal and the burn-in board back insertion detection terminal may be set with reference to the following modes: the front insertion detection end of the burn-in board is a first wiring terminal correspondingly connected with the grounding end on the burn-in board 400 when the front of the burn-in board 400 is inserted into the second physical interface 303; the burn-in board rear insertion detection terminal is a second connection terminal that is connected to the ground terminal on the burn-in board 400 when the second physical interface 303 is inserted into the burn-in board 400.
Fig. 4 is a schematic diagram of positions of an front insertion detection end of an burn-in board and a rear insertion detection end of the burn-in board according to an embodiment of the present invention, as shown in fig. 4, a grounding end is disposed on the burn-in board 400, so that a first connection terminal A1 on the right side of the second physical interface 303 in fig. 4 may be set as the front insertion detection end of the burn-in board, and a second connection terminal A2 on the left side may be set as the rear insertion detection end of the burn-in board. When the burn-in board 400 is inserted into the interface board 300, if the test host 100 detects that the level of the burn-in board front insertion detection terminal is pulled down, it is determined that the burn-in board 400 is being inserted; if the test host 100 detects that the level of the burn-in board backside insert detection terminal is pulled low, it is determined that the burn-in board 400 is back-inserted.
In an alternative embodiment, the number of second physical interfaces 303 is a plurality; each second physical interface 303 is rotatably connected to the interface board 300 in the horizontal direction.
In order to support engineers to measure the performance of a plurality of burn-in boards 400 at the same time, a plurality of second physical interfaces 303 may be provided on the interface board 300, and if a plurality of second physical interfaces 303 are provided to be arranged laterally in the horizontal direction, the size of the interface board 300 must be increased, so that in order to effectively control the size of the interface board 300 while satisfying the increase in the number of measurement requirements, the embodiment of the present invention provides that each second physical interface 303 is connected with the interface board 300 in a rotation manner in the horizontal direction. Fig. 5 shows a schematic view of a plurality of burn-in boards 400 inserted into the interface board 300 at the same time, in order to avoid that the lower burn-in board 400 is blocked by the upper burn-in board 400, the second physical interfaces 303 may be rotated in a horizontal direction, so that the burn-in boards 400 may be staggered, and thus an engineer may measure the electrical signals on the plurality of burn-in boards 400 at the same time.
In order to enhance the use experience of the burn-in board 400, so that the user is not limited to determining the insertion state and the insertion direction of the burn-in board 400 by the test host 100 of the burn-in machine, in the embodiment of the present invention, the burn-in machine further includes: inserting an indicator lamp; the insertion indicator light is connected with the test host 100; in the case where the burn-in board 400 is inserted into the second physical interface 303, the test host 100 controls the insertion of the indicator lamp to perform a preset color change or a preset shade change. Alternatively, the insertion indicator lamps are arranged in one-to-one correspondence with the second physical interfaces 303, and the insertion indicator lamps are not turned on when the burn-in board 400 is inserted; when the burn-in board 400 is inserted, the insertion indicator lights are turned on. Alternatively, when the burn-in board 400 is inserted, the insertion indicator light is red; when the burn-in board 400 is inserted, the insertion indicator light is green.
Further, the aging machine further includes: inserting a direction indicator lamp; the insertion direction indicator lamp is connected with the test host 100; in the case where the burn-in board 400 is inserted into the second physical interface 303, the test host 100 controls the insertion direction indicator to perform a preset color change or a preset shade change based on feedback of the burn-in board front insertion detection end and the burn-in board back insertion detection end.
In summary, according to the burn-in apparatus provided by the embodiment of the present invention, through the unique circuit structure of the interface board and the control of the mapping relationship of the test host to the signal switching component, the burn-in apparatus can support the front face up insertion of the burn-in board and the back face up insertion of the burn-in board, thereby greatly facilitating the measurement of the back electrical signal on the burn-in board by the engineer.
The embodiment of the invention also provides an interface board of the aging machine, which comprises: a first physical interface, a signal switching component, and a second physical interface.
