Description

Technical Field

[0001] The utility model relates to the technical field of FPC, in particular to a testing FPC device with double testing interfaces. Background Art

[0002] As LCD product technology matures, testing product functionality has become an important research and development direction. Therefore, test cables have come into being. Test cables are a flexible circuit board used to connect test equipment and tested products. They are also called FPCs. They are mainly used to test product functionality and have become an important research and development direction. By using FPC as the material for test cables, flexible and reliable test connections can be achieved, which can better meet the testing needs of LCD products and improve the accuracy and efficiency of product testing.

Therefore, for BTB connector products, only the required defined PIN pins can be tested through test points, and all PINs cannot be connected out of the test points. The test time is greatly increased and the test efficiency needs to be improved. Utility Model Content

[0021] The embodiment of the present application provides a test FPC device with dual test interfaces, which effectively solves the technical problem that the existing device has insufficient test efficiency when using a BTB connector.

[0022] Example

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem of insufficient testing efficiency of the existing device when using a BTB connector. The overall idea is as follows:

[0024] In view of the problems existing in the prior art, the utility model provides a test FPC device with dual test interfaces, including a flexible circuit board 11, a first BTB connector 12 is symmetrically arranged on the surface of the flexible circuit board 11, a polyimide film is fixedly installed on the surface of the two first BTB connectors 12, a second BTB connector 13 is arranged on the surface of the flexible circuit board 11, and the two first BTB connectors 12 are both located above the second BTB connector 13;

[0025] An auxiliary testing mechanism is fixedly mounted on a surface of the flexible circuit board 11 away from the first BTB connector 12;

[0026] The auxiliary testing mechanism includes a first test pad 14, which is connected to the first BTB connector 12. The auxiliary testing mechanism also includes a second test pad 15. The two second test pads 15 are both located on the surface of the flexible circuit board 11 away from the first BTB connector 12 and are fixedly installed. By arranging and connecting the first test pad 14 and the second test pad 15 on the basis of the test cable of the first BTB connector 12 and the second BTB connector 13, the testing process can be simplified, the number of plugging and unplugging operations and test points can be reduced, and the testing efficiency can be increased.

[0027] Both second test pads 15 are connected to the second BTB connector 13. The second test pad 15 is on the same side as the first test pad 14. The second test pad 15 is located below the first test pad 14. A steel sheet is fixedly installed on the outside of the second test pad 15. The steel sheet is rectangular. First positioning holes 16 are symmetrically provided on the surface of the flexible circuit board 11. By arranging a polyimide film on the surface of the first BTB connector 12 and a steel sheet on the surface of the second test pad 15 (a window is provided between the steel sheet and the bottom of the first BTB connector 12 for external ground connection and the resistance of the steel sheet is less than 5Ω), the first BTB connector 12 can be reinforced and protected, and the strength of the second test pad 15 can be increased, thereby increasing stability.

[0028] The two first positioning holes 16 are both on the same side as the first BTB connector 12. A second positioning hole 17 is provided on the surface of the flexible circuit board 11, and the second positioning hole 17 is located below the first positioning hole 16. A via groove 18 is provided on the surface of the flexible circuit board 11, and the via groove 18 is located between the second positioning hole 17 and the first positioning hole 16. By setting the first positioning hole 16 and the second positioning hole 17, the three places of the flexible circuit board 11 can be fixed by the clamping column in the subsequent testing of the first test pad 14 and the second test pad 15, which is convenient for measurement. In addition, by setting the via groove 18, the thickness of the flexible circuit board 11 can be effectively reduced and the bending performance can be improved.

[0029] Working principle:

[0030] In the first step, during measurement, the flexible circuit board 11 can be first fixed in the card column (the card column is an external period, which is used to be inserted into and fixed in the first positioning hole 16 and the second positioning hole 17 to assist in fixing the flexible circuit board 11) by using the first positioning hole 16 and the second positioning hole 17, and then the first test pad 14 and the second test pad 15 can be measured by the instrument respectively. At this time, the data tested by the first test pad 14 represents the PIN pin of the first BTB connector 12 (the first BTB connector 12 and the second BTB connector 13 are an electrical connector used to connect the mainboard or module of an electronic device, which is usually composed of two mating connectors, one connector is inserted into a device or module, and the other connector is inserted into another device or module to achieve electrical connection between them. The PIN pin refers to the needle-shaped or hole-shaped metal contact on the first BTB connector 12 and the second BTB connector 13), and the data tested by the second test pad 15 represents the PIN pin of the second BTB connector 13.

[0031] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
