The invention belongs to the technical field of PCB production testing equipment, and particularly relates to a program burn test machine. The program burn test machine comprises a working platform. Afeeding area and a discharging area are correspondingly arranged at the two ends of the working platform, the working platform is provided with two operation groups, and each operation group comprises a portal frame, a carrying mechanism, a plurality of PCB board test modules and a central positioning mechanism. The two portal frames are arranged between the feeding area and the discharging areaside by side, and each PCB board test module includes a lifting mechanism, an upper module, a linear motion module and a lower module. The first end of the linear motion module is located below the upper module, and the second end of the linear motion module extends out of the upper module, and the second ends of the linear motion modules of the operation groups and the corresponding central positioning mechanisms are located on the same straight line parallel to transverse beams. The PCB board test modules are densely distributed on the working platform, the test speed of the PCB boards is greatly improved, the working efficiency is improved, the movement track of the carrying mechanism is simplified, and the working efficiency is improved.
