In the related art, the integration degree of electronic devices is higher and higher, and electronic devices such as chips and a large number of sensors are integrated on a control main board. In order to achieve the extremely high stacking of devices in the limited space of the control motherboard, as shown in fig. 1, the electrical connection portion 31 for connecting the battery is designed on the rf circuit board 30, and the rf circuit board 30 is soldered on the control motherboard 10 through the interposer 20 to form a circuit board assembly (also called a sandwich board). When the control main board 10 needs to be overhauled, after the radio frequency circuit board 30 is detached, it is impossible to check whether the electronic device on the control main board 10 that needs to be subjected to the power-on test is damaged. In order to complete the electronic device requiring the power-on test, the rf circuit board 30 needs to be repeatedly soldered, resulting in inefficient repair and even damage to the circuit board assembly.

Based on this, this disclosure provides a test equipment, can improve maintenance efficiency.

For a better understanding of the test apparatus of the present application, further description is provided below in conjunction with the accompanying drawings.

The fixing element 200 is disposed in the carrying region 120, and the fixing element 200 includes a fixing element 210 for fixing the control main board 10 to the carrying board 100. The power supply assembly 300 is disposed on the carrier board 100, the power supply assembly 300 includes at least two conductive pins 310 for electrically connecting with the control motherboard 10, and the conductive pins 310 are disposed in the orthographic projection area of the avoiding hole 110 and/or the conductive pins 310 protrude the carrier area 120.

When the radiation maintenance equipment is used for maintaining the circuit board assembly, after the radio frequency circuit board 30 is disassembled, the avoiding hole 110 is used for avoiding other devices integrated on the control mainboard 10, the control mainboard 10 is placed on the bearing plate 100 and is electrically contacted with the at least one conductive pin 310, and the external power supply of the power supply assembly 300 is used for supplying power for the control mainboard 10.
