The resistance of conductive adhesive itself is very small, which is accurate to the actual side plate; 2. Very long opening time; 3. Soft conductive glue leaves no mark on the plate surface; 4. Resistivity is as low as 4.0 μΩ; 5. Method of use: spread the conductive adhesive on the test surface of the fixture for direct use to play the role of conduction; 6.

The fixture is light and thin, convenient to save and save space. The product is recommended to be applied to the test equipment by using the conductive adhesive pad, compared with the probe test, the probe is in contact with abrasion, and the number of times is large, which will pollute the gold surface of the probe, resulting in reduced conductive performance, which will bring unpredictable influence to the test, and the ACF is a compression test without damaging the structure.
[0004] Use ACF to fix on the test plate, the test plate is connected with the test box through the coaxial line, and the corresponding interval of the test plate corresponds to the test connector or the position of the gold finger module.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0023] As Figs. 1-3 shown, the utility model provides a novel camera test structure technical scheme:
[0024] Embodiment:
[0025] The test device mainly includes test base 1 and cover plate structure 2, and the middle part of the top of test base 1 is provided with placing cavity 3 for placing the camera module to be detected, placing disc 4 is arranged in the inner cavity of placing cavity 3, recess structure for installing detection mechanism is arranged in the middle part of the top of cover plate structure 2, and plug-in interface 5 for pin insertion is formed in one end of the bottom of cover plate structure 2, and the specific shape of the inner cavity of plug-in interface 5 is the combination of vertical cavity and trapezoidal cavity, and the large-diameter end of plug-in interface 5 faces test base.
[0026] Among them, limiting column 6 is fixedly installed at the four corner positions of the top of test base 1, and the top of limiting column 6 penetrates cover plate structure 2 and extends to the outside of the top of cover plate structure 2.
[0027] Among them, buffer spring 7 is sleeved on the upper and lower ends of the outer circle of limiting column 6, and limiting sheet is fixedly connected to the top end of limiting column 6.
[0028] Among them, guide column 8 is penetratively installed at the top four corner positions of placing disc 4, and limiting sheet is also fixedly installed at the top of guide column 8, the bottom of guide column 8 is fixedly connected with the bottom of the inner wall of placing cavity 3, and small spring 9 is sleeved on the outer circle of guide column 8.
[0029] The roller structure 10 is embedded in the middle of the top of the placing disc 4, and the positioning pressing strip 11 is fixedly installed in the middle of the bottom of the cover plate structure 2.
[0030] The roller structure 10 is rotatably installed on the top of the placing disc 4, and the positioning pressing strip 11 is a rubber strip, and the width of the rubber strip is less than the width of the placing disc 4.
[0031] In the embodiment, when the camera module is detected by using the device, the camera module to be detected is directly placed on the placing disc 4, and the pin of the camera module is located below the plug interface 5.
[0032] Then, the detection equipment can be powered on, and the detection personnel directly presses the cover plate structure 2 downward. When the pin of the camera module starts to contact the plug interface 5, due to the position, the pin structure is not in the up-down position relationship with the pin of the detection mechanism, so the camera pin gradually slides along the inclined surface of the plug interface 5 until it is connected with the detection mechanism. In this process, the pin structure of the detection mechanism does not have too much friction, but only contacts the camera pin structure.
[0033] In the process of pressing downward and adjusting the camera pin, since the pin needs to be adjusted, the roller structure 10 can be matched to more smoothly adjust the position. After adjustment, the positioning pressing strip 11 gradually increases the acting force between the camera module, so that the detection result is not easily affected by external factors during the detection process.
[0034] In the technical solution, firstly, the plug interface is designed by the vertically movable cover plate structure 2 and the specific shape of the inner cavity is a combination of a vertical cavity and a trapezoidal cavity. When the camera is detected, the pins do not rub each other, but only contact each other, which can improve the quality requirements for products, and the camera function can be realized under the condition of simple contact, that is, the product is excellent. Secondly, the pins are not excessively rubbed, and the number of cycles can be increased.
[0035] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
