Flexible circuit board and test tool

Abstract

The invention relates to the technical field of circuit testing and discloses a flexible circuit board and a test tool. The flexible circuit board includes a flexible body having a first crimping portion and an extension portion, wherein the first crimping portion is configured to be press-fitted into the second crimping portion of a substrate to be tested; a first electrical connection structurelocated at the first side of the flexible body, disposed on the first crimping portion and configured to be press-fitted into the a second electrical connection structure on the second crimping portion; and a support structure located on the first side of the flexible body and including a first support portion and a second support portion, wherein the first support portion is disposed on the extension portion and is configured to support the extension portion in a press-fit state to make the extension portion have the same horizontal height as the first crimping portion, and the second support portion is disposed on the first crimping portion and is configured to be supported between the first crimping portion and the second crimping portion in a press-fit state to isolate the first crimping portion from the second crimping portion. The flexible circuit board can be improved in press-fit effect and test success rate in a pseudo-pressure test.

Description

technical field [0001] The invention relates to the technical field of circuit testing, in particular to a flexible circuit board and a testing fixture. Background technique [0002] Generally, the method of visual (Cell Visual) test of the circuit unit of the display panel product is: connect each sub-pixel and the common electrode (Vcom) in the panel together, and then connect them to the corresponding probe test terminals on the panel respectively. (Pad), the gate signal is connected to the test terminal on the panel in the same way, and then the corresponding signal is added to each test terminal on the panel by pressing the probe, so that the panel displays the picture, so that Detect whether each thin film transistor (TFT) in the panel is operating normally, and whether the gate line (Gate) and the data line (Source) are routed normally, thereby preventing bad products from flowing into the module segment and causing cost waste. [0003] Generally, there is enough spa...

Problems solved by technology

However, when the flexible circuit board is pressed during the dummy pressure test, the flexible circuit board tends to deviate, which will easily cause the electrical connection structure on the crimping part of the flexible circuit board to be different from the electrical connection on the crimping part of the substrate to be tested. Poor crimping of the connection structure may even cause wrong connection and short circuit, which seriously affects the actual crimping effect and the success rate of the test
