The invention relates to the technical field of testing equipment, and provides a POL test load line and a preparation method thereof. The POL test load line comprises a load line body and a connection line; the connection line is composed of jumper lines, copper wires at two ends of each jumper line are exposed, and two ends of the jump lines are correspondingly welded; the load line body is exposed at both ends, one exposed end is plated with tin to form a copper wire interface, the other exposed end is used for connecting the electronic load; and one end of the connection line is connected with the copper wire interface of the load wire body and the other end is welded and fixed with a capacitance welding pad of a testing circuit so as to realize the current load test on a main board. In addition, the problem that the overlarge load line size damages the output capacitance welding pad and causes the physical damage to the main board is effectively reduced, the damage to the electronic devices around the welding pad is avoided, and convenience is brought to the load test.
Description
technical field [0001] The invention belongs to the technical field of test equipment, and in particular relates to a POL test pull wire and a preparation method thereof. Background technique [0002] With the vigorous development of big data, the server, as the basic hardware for big data storage, has become more and more important. Therefore, as the core of the server - the motherboard must also meet increasingly stringent quality standards during its testing process. In the motherboard test, the POL circuit test that provides various voltage outputs for it is undoubtedly one of the most important parts. At present, the current pulling wire (copper wire) is generally welded to both ends of the output capacitor by a soldering iron, and then an electronic load is used to perform a current pulling test. [0003] At present, the size of the copper wire at the interface of the current pulling wire is much larger than the size of the pad of the output capacitor at the motherbo...
