达达编号号: TW3304PA ' 九, invention description: [Technical field of invention] The present invention relates to a method and a detection device for a rubber material, and in particular to a method for detecting the adhesion accuracy of a glue material and detecting the same Install and set. [Prior Art] In recent years, flat panel display devices have become more and more popular among consumers due to their small size, light weight, and low radiation. In addition, due to the advancement of the process, the flat display device can continuously reduce the production cost while the display quality is greatly improved, so that the price of the flat display device can be popularized, and the market share is further improved. Among the various flat-panel display devices marketed on the market, liquid crystal display devices are most popular, becoming an indispensable electronic product in modern homes or offices. In the manufacturing process of a general thin film transistor liquid crystal display, it is often used. • A technique of Flip Chip Bonding on a flexible printed circuit board (FPC board) substrate, that is, driving The IC and its electronic components are placed directly on the film to save space on the substrate. This is commonly referred to as ChipO Film (COF) technology. When a soft film of COF technology is to be bonded to a printed circuit board (PCB), an anisotropic conductive film (ACF) is often used to bond the printed circuit board to the flexible film while making the printed circuit board. A plurality of conductive lines (a 6 1328682 three miscellaneous numbers: TW3304PA is called a gold finger) are connected to the corresponding conductive lines on the soft film. It is common practice to attach an anisotropic film to the surface of a printed circuit board and to detect the attachment of the anisotropic conductive film before performing other processing steps.

Since the anisotropic conductive film is generally translucent, the gray value attached to the conductive trace on the conductive line is lower than the gray value at the non-attached conductive film. The conventional detection method first defines a detection area on the circuit board, and sets a threshold gray value which is between the two gray values of the conductive film on the conductive line. Then, the gray values of the plurality of detection points in the electrical coupling are utilized, and then the gray values of the detection points are counted. The gray values of the detection points can be divided into a first part and a second part. The gray value of the first part exceeds the gray value of the threshold, and the gray value of the second part is lower than the gray value of the threshold. When the proportion of the gray value of the first part exceeds the second value 蚪', it is judged that the anisotropic conductive film is not attached to the printed circuit board (higher gray value), and the second part is grayed out. The ratio of the degree value = When the value exceeds a certain value, it is judged that the anisotropic conductive film is attached to the printed circuit (the gray value is low). However, the ash value of each conductive line is not the same due to process factors or material factors. Therefore, when the gray values of these detection points are counted, they are affected by different gray values of the conductive lines. When the color of the conductive lines is 2, it is easy to make the gray value of the _ points higher, and the printed circuit board with the adhesive conductive paste is mistakenly judged as the unattached conductive adhesive.时 When the color of some conductive lines is too dark, it is easy to make these detection points lower, and the printed circuit board without the anisotropic conductive adhesive is misjudged 7 1328682
