INSTRUCTIONS: [Technical Field] The present invention provides a detection system and method that utilizes the characteristics of light reflection to capture a two-dimensional image for determining line collapse. 1299890 [Prior Art] At present, in the process of wafer packaging, the gold wire of the pin can be used; its =: the phenomenon of local falling of the 发冈生* line, commonly referred to as the line collapse 瑕U read the brother-picture and the second Fig. 1 shows the schematic diagram of the normal gold line, and the second figure shows the schematic diagram of the line collapse of the gold line. The wafer 11 is tied to the edge connecting gold line 12'. Line 12 一下 The line rate is 27 degrees. This is the line meaning. The collapse of the line may cause a short circuit in the gold wire and the crystal wire. At the same time, the product may not be characterized. However, the wire collapses due to the collapse of the sheet metal line. Determine whether the wired thief exists, and the dragon gold towel crystal 4 is the same as the gold line on the edge will overlap in the image. It is impossible to detect the individual gold wire. The conventional method uses the three-dimensional non-contact I continuous number of points. Height, to find the line collapse, Μ _ can measure the gold line on the production line, and the gold line diameter section, three times ϋ; 4 degrees of material is enough to apply difficult. Therefore, most of the current operator by visual:: machine settings It is quite embarrassing, and the accuracy rate is very unstable. The method to detect the line collapse is to meet the above-mentioned requirements for improving the wafer sealing and slamming. The inventor based on the research of the detection efficiency of Yi Xiyi Design and topical discussion, the present invention proposes two-way experience, which is used as the implementation and basis of the above-mentioned expectation. The detection system and method 1299890 [Invention content] In view of the above problem The purpose of Ming is to provide a heavy method of 'the application of light reflection characteristics, the illumination system and the system in a specific direction and angle of incidence, so that ^ ^ light control = viewing angle - a two-dimensional image, two stereotypes, a sense The measurement, the plurality of illuminating elements and the arranging ^, the eve package 3 - the frame structure surrounds the workpiece to be tested, and senses the crying: "杈 group. The architecture is arranged in an arc system, and the control module uses an image to create an image, and the light-emitting component is turned on or off to generate a beam of light to the sensor to generate an image. , ', 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工 加工And the vertical surface incident light source, the line of the gold wire can be collapsed and highlighted, and a large number of subsequent calculations for the gold wire illumination are required. ^ '1, 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹 隹DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments and the following are provided. U-Tian's description of the text, such as 1299890 [Embodiment] The system residual correlation diagram' illustrates the detection according to the preferred embodiment of the present invention. ', wherein the same elements will be referred to by the same reference numerals for the two drawings. The block diagram showing the detection system of the present invention, in which the workpiece 35 to be tested, the detection system is at least 34 ^ The detector, the plurality of light-emitting elements 32, and a control module 〇〇ιν ^ surround the workpiece 35 to be tested in an arc structure, the sensor molds the image, and the light-emitting element 32 is disposed in the structure 31. The control is turned off, and the light-emitting element 32 is turned on or the 55 3S w #beam 36 is irradiated to the workpiece 35 to be tested, and is reflected to the sensing-W to generate an image. According to the foot, the texture of the workpiece 35 to be tested can be an opening of an integrated circuit. The printed circuit board (PCB) is produced by measuring the thread of a saw or a screw. The detection system can calculate the enemy-specific angle and some - if reflected to the sensor - according to the shape to be determined. Because the foot collapses or the snail always shows I, his condition, such as the connection of the integrated circuit 33, then the i-detector 33 has a flaw to contain the beam so that the beam cannot be reflected to the sensor. Normal: then: foot Qiu (three) Produce an image of still #11. For example, if the pin shape of the pin is a brighter image, if the shape of the pin is used, the image of the two legs is a darker image. Thereby, the complexity required for the processing of the in-and-two shirts is reduced and the accuracy of the image judgment is improved. Preferably, the above-mentioned control module is a microcontroller for performing the opening or closing of the above-mentioned light-emitting elements (Light Emitting Diodes, LEDs), and the above structure 7 1299890 is preferably a printed circuit. The board is constructed.
