Problems solved by technology

At this time, testers often cannot immediately know the reason why the host computer crashes, let alone directly find out that it is because of a problem with that electronic component on the motherboard of the host computer.
[0004] Therefore, at present, when conducting electrostatic discharge tests, it is often necessary to rely on the experience of testers to speculate where the electrostatic problem occurs, and then repeatedly test related components that may cause product malfunctions
In this way, it will be very labor-intensive and testing man-hours

[0015] Please refer to FIG. 1 , which is a schematic diagram of an electrostatic discharge testing device according to a first embodiment of the present invention. The electrostatic discharge testing device 100 includes a testing platform 110 , a static electricity generating unit 120 , a switch element 130 , and a grounding interface 140 , wherein the testing platform 110 is provided with a plurality of wires.

[0016] The above-mentioned test platform 110 is coupled with the ground interface 140 so that the test platform 100 is grounded, that is, the test platform 110 can introduce its accumulated electrostatic charge into the ground terminal through the ground interface 140, so as to avoid the test platform 110 from being repeatedly input by static electricity. Pulse P and accumulate too much static electricity, resulting in the user may be endangered.

[0017] The switch element 130 is respectively coupled to the wires of the test platform 110 and the static electricity ge...

[0028] Please refer to FIG. 2 , which is a schematic diagram of an electrostatic discharge testing device and a static electricity generating unit according to a second embodiment of the present invention. This embodiment is similar to the above-mentioned first embodiment, but the ESD testing device 100' in this embodiment does not use a switching element. In this embodiment, the electrostatic generating unit 120' uses an electrostatic gun as an electrostatic discharge device. In this way, when the tester intends to perform an electrostatic discharge test, he can selectively contact the static electricity generating unit 120' with one of the wires L1-Ln and L1'-Lm', and provide an electrostatic pulse P to the wire (such as The first wire L1 of FIG. 2).

[0029]The difference between this embodiment and the above-mentioned first embodiment is that the static electricity generating unit 120 in the first embodiment can automatically and respectively provide static electricity pu...

[0031] Please refer to FIGS. 3A and 3B . FIG. 3A is a schematic diagram of an electrostatic discharge testing device according to a third embodiment of the present invention, and FIG. 3B is a schematic diagram of another placement angle of the object D in FIG. 3A . The difference between the third embodiment and the first embodiment is that the test platform 210 of the electrostatic discharge testing device 200 only lays out the first horizontal wires l1˜ln.

[0032] At this time, the test of the first embodiment is performed with the placement angle of the object D shown in FIG. 3A . After testing the first conductive wires l1-ln with the electrostatic pulse P, for example, it is obtained that the area a1 corresponding to the first conductive wire l1 in the object under test D contains the test failure object. At this time, the user can rotate the object D to be tested by a preset angle, such as 90 degrees clockwise, so that the relative positions of the first wires l1-ln and...

Abstract

An electrostatic discharge testing device and method is used for searching the failed objects in testing among the substances to be tested. Firstly, the substance to be tested is placed on a testing platform provided with a plurality of wires. Secondly, one of these wires is provided with the static pulse. Finally, if the substance to be tested makes a false move, the region of the corresponding wire among the substances is featured by a failed test object.

Description

technical field [0001] The present invention relates to an electrostatic discharge testing technology, and in particular to an electrostatic discharge testing device and method thereof. Background technique [0002] Electrostatic Discharge (ESD) is the main factor causing most electronic components or electronic systems to be damaged by electrical overstress (Electrical Overstress, EOS). Such damage will cause semiconductor components and computer systems to malfunction or form a permanent damage, thereby affecting the circuit function of integrated circuits (Integrated Circuits, ICs), and making electronic products not work properly. Therefore, all electronic products currently on the market must pass the electrostatic discharge test in the electromagnetic compatibility test before they can be sold. At present, when performing electrostatic discharge tests, an electrostatic discharge generator (ESD generator) (also known as an electrostatic gun) that complies with regulati...
