Therefore, the technical scheme of the embodiment effectively solves the problem of poor universality of the burn-in test device caused by that the burn-in test device of the PCB module can only perform burn-in test on the PCB module with a single size.

The tested piece refers to a PCB module. The first supporting beam 30 provides a placement position for the PCB module, and the second supporting beam 50 is fixed on the bearing frame 20, so that the position of the PCB module can be fixed, namely, the second supporting beam 50 can be adjusted according to the size of the PCB module placed on the first supporting beam 30, so that the aging test device can perform aging test on the PCB modules with different sizes, and the universality of the aging test device is improved.

When the first magnetic member 41 is mounted to the first magnetic member 42, the position of the first support beam 30 is fixed. The first magnetic member 41 and the first magnetic attraction member 42 facilitate the process of mounting and dismounting the first support beam 30 to and from the carrier frame 20.

The hollowed-out area 52 also enables the position of the adaptor 70 on the second support plate to be adjustable, namely, the distance between the adjacent adaptors 70 is adjustable, so that the PCB modules with different sizes can be mounted to the adaptors, and the universality of the burn-in test device is improved.

Specifically, the adapter 70 has an interface to connect the PCB module so that the PCB module can be mounted to the adapter 70. The adaptor 70 is mounted on the second support plate 51, and an avoidance area for mounting the adaptor 70 is arranged on one side, close to the PCB module, of the second support plate 51, so that the positions of the adaptor 70 and the second support plate 51 can be relatively fixed, and further the positions of the PCB module mounted on the adaptor 70 and the second support plate 51 can be relatively fixed.

Preferably, the material of the platen 53 may be iron, which allows for lower cost manufacture of the platen. Of course, in the embodiment not shown in the drawings, the material of the pressing plate 53 may be a ferromagnetic substance such as cobalt or nickel.

As shown in fig. 1 and 3, in the present embodiment, the pressing plate 53 is located at both sides of the second support plate 51, and the connection structure 54 includes the third magnetic member 541 and the third magnetic member 542, one of the third magnetic member 541 and the third magnetic member 542 is disposed on the second support plate 51, and the other of the third magnetic member 541 and the third magnetic member 542 is disposed on the pressing plate 53. The third magnetic member 541 and the third magnetic attraction member 542 allow the pressing plate 53 to be attached to the second support plate 51 or detached from the second support plate 51. The pressing plate 53 may be removed from the second support plate 51 when the third magnetic member 542 is removed from the third magnetic member 541, and the pressing plate 53 may be fixed to the second support plate 51 when the third magnetic member 542 is mounted to the third magnetic member 541.
