Description

False pressure test fixture of touch-sensitive screen sensor function piece

Technical Field

The utility model relates to the technical field related to touch screen testing, in particular to a false pressure testing jig for a functional sheet of a touch screen sensor, and particularly relates to a universal clamping jig for checking the electrical functions of a flexible circuit board (FPCA) with a chip and a peripheral circuit.

Background

In the production process of the touch screen, a functional sheet (hereinafter referred to as a sensor) with sending and receiving electrodes and a flexible circuit board (hereinafter referred to as FPCA) with a chip and a peripheral circuit are required to be pressed and bound into a semi-finished product (hereinafter referred to as FOG) by using anisotropic conductive adhesive (hereinafter referred to as ACF), and the process is hot-pressed (the functional sheet and the flexible circuit board are kept for a certain time after being heated and pressurized and then released and slowly restored to normal temperature), so that the functional sheet and the flexible circuit board are not easy to separate after being pressed mutually. However, if malfunction occurs after hot pressing, analysis and inspection are required, and it is troublesome to analyze malfunction due to FPCA or a sensor or hot pressing, and it is necessary to separate FPCA from a sensor for inspection, which wastes man-hours and easily causes defective and scrapped products. Therefore, before hot pressing production, a false pressing test is required to be performed on the product, and the false pressing test is used for screening out bad products and preventing waste of the manufacturing process.

Through mass search, the prior art publication number is CN204302402U, and a sensor false pressure test fixture for a capacitive screen is disclosed, which comprises a base, a bracket vertically and fixedly connected with the base, and a guide rail arranged on the bracket, wherein the guide rail is arranged in parallel with the bracket, the bottom end of the guide rail is connected with a movable pressure head, the movable pressure head slides up and down along the guide rail, an FPC board corresponding to the movable pressure head in position is arranged on the base, a sensor functional sheet is arranged on the FPC board, and the P pin of the sensor functional sheet is aligned with the P pin of the FPC board; according to the utility model, the structure is adopted, the FPC board is connected with the test board, and the test board and the sensor functional sheet are subjected to false pressure test to realize the test effect, so that the manufacturing cost is effectively reduced, the production period is shortened, the test precision is high, and the test efficiency is high. In addition, the test fixture has reasonable design, simple structure, convenient use and easy popularization and use.

In the false pressure test, the product needs to connect the FPCA with the sensor, but in order to ensure the repeated utilization rate of the sensor, the hot-pressed sensor is generally prolonged by a section of bridging flexible circuit board (called FPC hereinafter) without a chip and a peripheral circuit, and then the golden finger of the FPCA to be tested is directly contacted with the golden finger of the bridging FPC hot-pressed on the sensor to perform the false pressure test, so that the product and a test object can be separated. The sensor functional sheet which is subjected to hot pressing and bridging of the FPC is fixed in the test process, and the FPCA to be tested is clamped after being positioned and fixed, so that the matched clamping jig is required to be fixed, the relative positions of all parts of the existing jig are not adjustable, and the existing jig cannot be suitable for products with different sizes and different shapes.

In view of the above-mentioned drawbacks, the present inventors have actively studied and innovated to create a test fixture for testing the false pressure of a functional chip of a touch screen sensor, so as to make the test fixture have industrial application value.
