New description: [New technology field] This creation department is about PCB inspection, especially for detecting residual residue of PCB after laser drilling and PCB cleaning. In the tenth preferred case, the wavelength projected onto the printed circuit board after the Fluorescence Filter is between 430 and 495 nm. [Prior Art] Traditionally, printed circuit boards (PCB boards) must be subjected to laser drilling operations before printing to form various holes (as shown in FIG. 1) on the printed circuit board as Various settings and circuit conduction. Only in the process of drilling, it is possible to leave residual glue on the periphery, inner wall, or bottom of the hole (as shown by the black dots in Figure 1), thus affecting the conductive quality and good quality of the printed circuit board after the hole. Rate, and it is unsightly, so it is necessary to remove these glues and chemicals before further processing. [New content] The purpose of this creation is to propose a system for detecting residual glue of PCB after laser drilling and PCB cleaning, which can quickly and effectively detect residual slag after laser drilling of PCB. . In order to achieve the above object, the present invention proposes a system for detecting residual glue of a PCB after laser drilling and a post-cleaning agent of the PCB, the system comprising: a machine for placing a printed circuit board, wherein the printed circuit board Laser drilling has been applied; a fluorescent microscope has a built-in full-band light source that excites the fluorescent light of the analyte through the fluorescent filter (the wavelength of the fluorescent filter (Fluorescence Filter) is projected onto the printed circuit board) 430~495nm (nanometer) and projected to the laser drilling of the printed circuit board on the machine'. The light projected by the fluorescent microscope is irradiated on the printed circuit board with glue or residual drug residue. Fluorescent; a fluorescent sensing camera mounted on the third eyepiece of the image of the Labo microscope to capture the printed circuit board through the fluorescent microscope; and an image processing computer 'for display The image taken by the camera is processed and processed; wherein the printed circuit board is first placed in the appropriate position on the machine; then the projection position of the fluorescent microscope is adjusted manually or automatically. Go to the printed circuit (4) Laser Drilling or Residues of the Reagents and the image of the printed circuit board at the eyepiece of the fine-grained micromirror, due to the hole in the hole of the printed circuit board and the bottom of the hole. The glue or the residue of the drug is after the fluorescent irradiation: = obviously shows the camping signal, and it is very different from the printed circuit board. Therefore, it is determined by the image processing computer that the ingested = Whether there is glue or _ residue in the drill hole. Advantages, read the steps to understand the characteristics of this creation and its [implementation] I would like to discuss the structure of the case 'and the power and advantages that can be produced' A preferred embodiment of the present invention is described in detail below. The present application proposes a printed circuit board that uses a full-wavelength light source (mainly a light source that can excite the fluorescent light of the object under test), especially the edge of the hole and the bottom of the hole in the printed circuit board. 'On the other hand, a fluorescent sensing camera (such as a C c D camera with a spot metering or long exposure, or a digital camera will produce a weak fluorescent response for long exposure to increase discrimination). The light source of the printed circuit board is exposed to the image for a long time exposure. Since the image of the hole in the hole of the printed circuit board and the bottom of the hole in the hole is exposed for a long time, the fluorescent signal is obviously displayed. It is very different from the rest of the printed circuit board, so the tester can easily detect the residual glue or whether there is any drug residue, and perform inspection or cleaning on the printed circuit board. Please refer to Figure 2 and Figure 3. Figure 2 shows the component architecture diagram of this creation. Figure 3 is another component architecture diagram of the present case, which contains the display and memory components. The system description of this creation is as follows. A machine 10 is used for placing a printed circuit board (PCB). The board is 2), wherein the printed circuit board has been subjected to laser drilling and forms a hole 21 with a large lower jaw on the taper, and the residual glue is left at the edge or wall or bottom of the hole. The printed circuit board 20 is an original board on which an upper circuit has not been printed, and is usually composed of an upper layer of a base material layer sandwiching two upper and lower copper layers. A fluorescent microscope 30 has a built-in full-band light source that excites the fluorescent material of the test object, passes through a fluorescent filter (Fluorescence Filter Cube), and is projected onto the printed circuit board 20 on the machine table 10. The projected position can be manually or mechanically operated to change the projection point of the light to scan at different locations on the printed circuit board. The light projected by the fluorescent microscope 30 is irradiated on the printed circuit board 2, and there is a residue at the residue or a residual of the drug. The preferred state in this case is that the wavelength projected onto the printed circuit board after the Fluorescence Filter is between 430 and 495 nm (nanometer). A fluorescent camera or digital camera 40 with spot metering or long exposure is placed at the third eyepiece of the fluorescent microscope 3, and the printed circuit board 2 is photographed via the fluorescent microscope 30. The camera 40 can be a CCD camera or a digital camera. An image processing computer 5 〇 ' is used to display images taken by the camera 4 (). The image processing computer may be integrally formed with the camera or externally attached to the camera. The following devices can be attached to this creation. : S Remembrance 60 is used to record the images taken. The motor automatically controls the honometer microscope and the position of the camera to the desired position. Placed in the talk; for the description of the next test, the printed circuit board is first calibrated. (4) Adjust by manual or automatic method: the camera position of the mirror machine _=: = brush circuit board camera, because the light in the hole of the printed circuit board will be very clear, the image of the residual glue after the irradiation is exposed for a long time. The remaining & other parts of the printed circuit board, so the image displayed by the image display can determine whether there is residual glue or drug residue in the hole to determine whether the printed circuit needs to be The board is cleaned (washed). The advantages of the progressive nature of the breakup have indeed improved the efficiency. The cost case has not been disclosed or disclosed in domestic and foreign countries. The humanized design of this case is quite in line with actual needs and improves the detection rate of PCB residual glue. Improve the yield of the pCB process. Its specific improvement is that the existing detection is missing, and it is obviously protruding and not easy to reach compared with the prior art.
