The invention provides a high-density printed circuit board (PCB) test machine comprising a material platform, PCB clamping sampling mechanisms, an automatic material feeding and discharging device, a test clamp and a central controller. Due to the combination of the operation of the automatic material feeding and discharging device and the control of the alignment of the PCB clamping sampling mechanisms and the test clamp, the PCB can be tested automatically, and the PCB test capacity, precision and efficiency of the high-density PCB test machine can be greatly improved. The invention also provides a high-density PCB test method based on the high-density PCB test machine. Due to the unified material loading and the combination of the two PCB clamping sampling mechanisms, the two PCB clamping sampling mechanisms can collect the images of the PCBs thereon at the same time and feed back the collected images of the PCBS to the central controller to test the alignment of the two PCB clamping sampling mechanisms and the test clamp. Due to the timely material unloading and the material reloading after the test of two PCB clamping sampling mechanisms and the test clamp, the standby time of the test clamp is shorted to the maximum extent, the whole test process is standardized, and the test efficiency is ensured.

The present application provides a test method for verifying SSM response rules, the method comprising: the test device sends a synchronous Ethernet signal through the first port; when the device under test receives the synchronous Ethernet signal sent by the test device through the fourth port, press the configured The SSM response rule sends the corresponding synchronous Ethernet signal to the test device through the fourth port and the fifth port, and sends the corresponding framed 2Mb / s external timing signal to the test device through the sixth port; the test device receives the synchronization sent by the device under test When the Ethernet signal and the framing 2Mb / s external timing signal are used, determine whether the received SSM value is the same as the configured SSM value; and record the comparison result; when the test equipment determines that any of the recorded comparison results are different, determine the tested The SSM response rule of the device is incorrect, and the SSM value corresponding to the records with different comparison results is displayed. This method can improve testing efficiency and reduce human errors.
