The other end of the test circuit board is provided with several analog interfaces in one of the embodiments,.
It in one of the embodiments, further include lid, one end of the lid and the base are hinged, the lid
The other end is snapped connection with the base, and the pressing piece is set on the lid.
The height of the probe is lower than the height of the elastic plate in one of the embodiments,.
The above-mentioned detection jig for touch screen chip, using test circuit board simulate touch screen, in test when, only need by
The plug that interface is arranged terminates on any one computer, then can be carried out touch screen chip testing, just without assembled machine table
The test of touch screen may be implemented, to save a large amount of time, improve working efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the detection jig for touch screen chip of one of embodiment.
Specific embodiment
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing to this
The specific embodiment of utility model is described in detail.Many details are explained in the following description in order to abundant
Understand the utility model.But the utility model can be implemented with being much different from other way described herein, this field
Technical staff can do similar improvement without prejudice to the utility model connotation, therefore the utility model is not by following public affairs
The limitation for the specific embodiment opened.
It should be noted that it can be directly another when element is referred to as " being fixed on " or " being set to " another element
On one element or there may also be elements placed in the middle.When an element is considered as " connection " another element, it can be with
It is directly to another element or may be simultaneously present centering elements.Term as used herein " vertically ", " level
", "upper", "lower", "left", "right" and similar statement for illustrative purposes only, be not offered as being uniquely to implement
Mode.
As shown in Figure 1, a kind of detection jig for touch screen chip, including base 1, pressing piece 2, testboard 3 and survey
Circuit board 4 is tried, the base 1 is provided with mounting groove 11.
Testboard 3 includes that elastic plate 31 and several probes 32 for being distributed in elastic plate 31, probe 32 are located in elastic plate 31,
Pressing piece 2 is covered on elastic plate 31, and elastic plate 31 is set in mounting groove 11, and is formed and used between elastic plate 31 and base 1
In the working position for placing IC chip.The height of probe 32 is lower than the height of elastic plate 31.The pressing of pressing piece 2 is placed on working position
IC chip, at this point, elastic plate 31 is compressed, probe exposes elastic plate 31, and probe is electrically connected with IC chip.
Test circuit board 4 is arranged in base 1, and one end of test circuit board 4 is provided with to be connect for the test of connecting test device
Mouth 41, probe 32 are abutted with test circuit board 4.Tester can be the detection device of profession, is also possible to common computer, is used for
Show test data.
The above-mentioned detection jig for touch screen chip when test, is only needed using test 4 simulated touch screen of circuit board
The plug that interface is arranged is terminated on any one computer, then can be carried out touch screen chip testing, is not necessarily to assembled machine table
It can realize the test of touch screen, to save a large amount of time, improve working efficiency.
The other end for testing circuit board 4 in one of the embodiments, is provided with several analog interfaces.Setting simulation connects
Mouthful, by adjusting the connection of analog interface, to simulate the touch screen of more bells number He specification, make the inspection for touch screen chip
