TECHNICAL FIELD

[0002] A half-hole module refers to an electronic module with a specific design, which is characterized by a small size and a close pitch of the half-hole structure on the peripheral side of the module. In the production process of the half-hole module, a detection tool is required to detect the module during the processes of downloading programs, burning product identifiers (PID), testing related functions, and burning end ID (CID).
[0003] The conventional detection tool in the related art generally includes a detection box, a mainboard placed in the detection box, a probe connected to the mainboard by a wire, the probe passing through the detection box, a pressing block arranged on the upper part of the detection box for fixing the module to be detected, and a shielding cover. During detection, the module to be detected is placed on the probe connected to the mainboard, the pressing block is used to press the two sides of the module to be detected, and then the shielding cover is placed on the upper part of the module to be detected. After fixing, the detection switch is started to begin detecting the module to be detected. The conventional detection tool needs to contact the pads on the back of the module to be detected by the probe to connect and test the module. The contact between the probe and the pads of the module to be detected requires the size and pitch of the pads. The size of the pads on the back of the module limits the size of the entire module. Moreover, the more pads of the module to be detected, the more connecting wires between the mainboard and the probe, which leads to connection errors during detection. This makes the conventional detection tool unable to detect the half-hole module with small size and small pitch of the half-hole structure on the side, and the conventional detection tool has a long processing time, high cost, and low production efficiency.
