Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.
[0041] To solve the technical problem that the existing test device cannot be universal and has low reusability when testing a module under test, the present application provides a test device and a test method, which can separate the high-speed signal test circuit and the low-speed signal test circuit from the functional test fixture. The low-speed signal test circuit is integrated into the automated equipment test box, and the high-speed signal test circuit is integrated into the companion test board. After the functional test fixture fixes the module under test, it connects the pins of the module under test to the automated equipment test box and the companion test board, so that the upper computer can control the automated equipment test box and the companion test board to perform functional tests on the module under test, improving the universality of the test device when testing the module under test and the reusability of the test circuit.
[0042] The first embodiment of the present application provides a test device, which can be applied to a system architecture as Figure 1 shown. The system architecture at least includes a functional test fixture, an automated equipment test box, a companion test board, and an upper computer.
[0043] Among them, the functional test fixture is used to fix the module under test and connect the pins of the module under test to the automated equipment test box (abbreviated as ATE-BOX) and / or the companion test board (abbreviated as CPB); among them, the automated equipment test box includes a low-speed signal test circuit, and the companion test board includes a high-speed signal test circuit.
[0044] The upper computer is used to control the automated equipment test box and / or the companion test board to perform functional tests on the module under test.
[0045] This test device separates the high-speed signal test circuit and the low-speed signal test circuit from the functional test fixture. The low-speed signal test circuit is integrated into the automated equipment test box, and the high-speed signal test circuit is integrated into the companion test board. After the functional test fixture fixes the module under test, it connects the pins of the module under test to the automated equipment test box and the companion test board, so that the upper computer can control the automated equipment test box and the companion test board to perform functional tests on the module under test, improving the universality of the test device when testing the module under test and the reusability of the test circuit.
[0046] In a specific embodiment, the schematic structural diagram of the test device is as shown in Figure 2 , and next, the test device will be described in detail based on the schematic structural diagram of the test device.
[0047] In one embodiment, the test device further includes a programmable power supply, which is used to supply power to the module to be tested, the automated equipment test box, the accompanying test board, and the host computer.
[0048] In one embodiment, the functional test fixture includes a fixture board, and the fixture board includes a socket structure unit, a first connector, and a second connector.
[0049] The socket structure unit can also be referred to as the SOCKET structure. The SOCKET structure is used to connect the first pin group of the module to be tested to the first connector, and the second pin group of the module to be tested to the second connector; wherein, the first connector is used to connect the automated equipment test box, and the second connector is used to connect the accompanying test board.
[0050] In this embodiment, the module to be tested can be fixed to the functional test fixture through the SOCKET structure, and the fixing method is not limited. For example, it can be fixed by clamping or fixing parts. At the same time, the SOCKET structure can connect a part of the pins (the first pin group) in the module to be tested to the first connector, and a part of the pins (the second pin group) to the second connector. Since the first connector is connected to the ATE - BOX and the second connector is connected to the accompanying test board, the host computer can control the ATE - BOX and the accompanying test board to perform functional tests on the module to be tested.
[0051] In one embodiment, the socket structure unit includes a plurality of thimbles. When the module to be tested is fixed to the socket structure unit, the pins of the module to be tested are connected to the thimbles one by one.
[0052] In this embodiment, the SOCKET structure can include a plurality of thimbles. The thimbles are designed elastically. When the module to be tested is fixed to the SOCKET structure, the thimbles contact and are compressed by the pins of the module to be tested, forming a good conduction path. The other end of the thimble is connected to the first connector or the second connector, so as to conveniently and quickly lead out the pins of the module to be tested to the first connector or the second connector through the thimbles.
[0053] In one embodiment, the automated equipment test box includes a micro - control unit function board (abbreviated as MCU function board) and a peripheral circuit board (which can be abbreviated as T1), as shown in Figure 3 , and the MCU function board is connected to the peripheral circuit board T1 through a third connector.
[0054] The peripheral circuit board T1 is used to perform functional tests on the low-speed signals of the module under test under the control of the MCU function board, and the co-test board is used to perform functional tests on the high-speed signals of the module under test under the control of the microcontroller unit function board.
[0055] In this embodiment, the MCU function board and the peripheral circuit board T1 are separately designed and connected through the third connector, which can modularize the automated equipment test box. For example, both the peripheral circuit board and the MCU function board can be detachably connected to the third connector. When other test devices need them, the MCU function board or the peripheral circuit board T1 can be separately disassembled and used, improving the reusability of the components.
[0056] In one embodiment, the automated equipment test box is detachably connected to the first connector, and the co-test board is detachably connected to the second connector.
[0057] In this embodiment, the connection between the ATE-BOX and the first connector can also be a detachable connection, and the connection between the co-test board and the second connector can also be a detachable connection, making the components modular. If the peripheral circuit is designed on the fixture board, due to the limited area of the fixture board, the structural design requirements for the fixture board are very high. In this embodiment, the high-speed signal test circuit and the low-speed signal test circuit are no longer designed on the fixture board, but separated from the functional test fixture. The low-speed signal test circuit is integrated into the automated equipment test box, and the high-speed signal test circuit is integrated into the co-test board. Moreover, both the ATE-BOX and the co-test board are detachably connected to the corresponding connectors. For example, when the co-test board is not needed, it is not connected. On the premise of being convenient to connect, the expandability of the functional test is improved, and the reusability of the test circuit is also improved.
[0058] In one embodiment, the low-speed signal test circuit, such as Figure 4 can include any combination of one or more of an audio (AUDIO) test circuit, a general-purpose input / output test circuit (General Purpose Input / Output, abbreviated as GPIO), a subscriber identity module (Subscriber Identity Module, abbreviated as SIM) test circuit, a secure digital card (Secure Digital Card, abbreviated as SD) test circuit, a digital-to-analog conversion (DAC) test circuit, an analog-to-digital conversion (ADC) test circuit, a USB2.0 interface test circuit, a serial port debugging (DEBUG_UART) test circuit, and a light-emitting diode (LED) test circuit.
[0059] The high-speed signal test circuit, such as Figure 5, may include any combination of one or more of a Mobile Industry Processor Interface LOOP (abbreviated as MIPI-LOOP) test circuit, a peripheral component interconnect express (abbreviated as PCIE) test circuit, a Serial Gigabit Media Independent Interface (abbreviated as SGMII) test circuit, a TYPE-C interface test circuit, a USB3.0 interface test circuit, and an Extended Circuit test circuit.
[0060] In this embodiment, the low-speed signal test circuit integrated into the ATE-BOX can be configured as needed, and the high-speed signal test circuit integrated into the companion board can also be configured as needed. It should be understood that the low-speed signal test circuit integrated into the ATE-BOX may also include other low-speed signal test circuits such as a JIG-CON test circuit, and the high-speed signal test circuit integrated into the companion board may also include other high-speed signal test circuits such as a CPB-CON test circuit, so that the functional test of the test device is more comprehensive and universal.
[0061] In one embodiment, the automated equipment test box further includes a Power Protect Board (abbreviated as PPB), which is used to provide overvoltage and overcurrent protection for the microcontroller unit function board and the peripheral circuit board.
[0062] In this embodiment, the ATE-BOX further includes a power protection board, so as to provide overvoltage protection and overcurrent protection for the MCU function board and the peripheral circuit board. Of course, functions such as under-voltage detection and adjustable protection threshold can also be performed, without limitation, so as to improve the safety during the functional test.
[0063] In the above embodiments of the present application, the host computer can be an industrial control computer or a personal computer PC. A tool software is installed in the host computer. Next, examples of low-speed signal test and high-speed signal test will be given respectively.
[0064] When testing low-speed signals, the tool software sends AT commands to control the PIN of the module under test to output high / low levels; the voltage signal is collected by the MCU function board after passing through the fixture board and the ATE-BOX, and the voltage value is sent back to the tool software through the serial port; the tool software compares the collected voltage with the threshold. If it is within the threshold, the low-speed signal test of this PIN passes (PASS), and it is judged that its path is normal. It should be noted that the test schemes for each low-speed signal (such as SIM, SD, AUDIO) all rely on the peripheral circuit board T1 in the ATE-BOX for auxiliary testing, which will not be listed one by one here.
[0065] When testing high-speed signals, such as testing MIPI_LOOP, the tool software controls the PIN under test of the module under test to output MIPI signals, such as Display Serial Interface (DSI) signals; the DSI signals are input to the MIPI signal conversion circuit on the CPB after passing through the fixture board, and are converted into Camera Serial Interface (CSI) signals; the CSI signals are sent back to the module after passing through the fixture board, received by the CAMERA of the module, and sent to the tool software. The tool software judges whether the DSI signals output by the module are consistent with the CSI signals received; if they are consistent, the MIPI_LOOP test passes. The test principles for other high-speed signals are similar (the module sends high-speed signals, which are converted by the peripheral circuit on the CPB and then sent back to the module, and the module judges whether the signals it sends and receives are consistent, or sends them to the tool software for judgment), and all use the loopback scheme for testing, which will not be listed one by one here.
[0066] In each embodiment of the present application, the high-speed signal test circuit, the low-speed signal test circuit are separated from the fixture board. The low-speed signal test circuit is integrated into the ATE-BOX, and the high-speed signal test circuit is integrated into the CPB. Both adopt a normalized design, which improves their reusability and expandability, and reduces the manufacturing difficulty and cost of the fixture board.
[0067] Based on the same technical concept, the second embodiment of the present application provides a test method, as Figure 6 applied to the test device described in any one of the first embodiments, the test method includes:
[0068] Step 601, when the module under test is fixed to the functional test fixture, the host computer controls the target pin of the module under test to output a functional test signal;
[0069] Step 602, the automated equipment test box or the accompanying test board tests the functional test signal to obtain a test feedback signal;
[0070] Step 603: The host computer generates the functional test result of the module to be tested based on the functional test signal and the test feedback signal.
[0071] In this test method, with the module to be tested fixed on the functional test fixture, the host computer controls the target pins of the module to be tested to output the functional test signal; the automated equipment test box or the accompanying test board tests the functional test signal to obtain the test feedback signal; the host computer generates the functional test result of the module to be tested based on the functional test signal and the test feedback signal. Since the used test device separates the high-speed signal test circuit and the low-speed signal test circuit from the functional test fixture, integrates the low-speed signal test circuit into the automated equipment test box, and integrates the high-speed signal test circuit into the accompanying test board, after the functional test fixture fixes the module to be tested, it connects the pins of the module to be tested to the automated equipment test box and the accompanying test board, so that the host computer can control the automated equipment test box and the accompanying test board to perform functional tests on the module to be tested, making this test method simply and efficiently complete the functional test of the module to be tested.
