Fig. 1 is a schematic view of a circuit board re-inspection marking system according to an embodiment of the present application, where the system includes a computer device for controlling re-inspection marking, a line scanning camera, and a marking machine. Alternatively, the marking machine and the line scan camera may be an all-in-one device. The line scanning camera part is responsible for scanning the material substrate to obtain a panoramic material image, namely the front and back images of the whole substrate, and the panoramic material image is transmitted to the computer equipment for rechecking and marking. The marking machine part is used for marking defective target pcs particles at the target position of the material substrate according to the instruction, and particularly can be a laser marking or etching method and the like. Optionally, the line scanning camera and the mechanical arm of the marking machine synchronously move, or camera equipment is additionally arranged on the arm of the marking machine, and when marking, the corresponding target pcs particle picture is transmitted to computer equipment for display.
The computer device is a device with a display, and the display displays a reinspection marking interface for the visual operation of the manual marking process. The computer equipment is connected with the line scanning camera and the marking machine in a wired or wireless communication manner, receives the scanned material panorama and the real-time marking picture, and simultaneously sends marking instructions and positioning scanning instructions to the marking machine and the line scanning camera.
Fig. 2 is a flowchart of a circuit board reinspection marking method provided by an embodiment of the present application, including the following steps:
step 201, displaying a reinspection marking interface, wherein the reinspection marking interface comprises a panoramic material display area and a real-time marking area;
the review marking interface is a display interface of the review marking system carried by the computer device in fig. 1, and an operator can complete linkage operation only through the computer device because the visual and contrast operation is to be realized.
Referring to fig. 3, a schematic diagram of a review marking interface is shown, and the review marking interface 300 includes at least a panoramic material display area 310 and a real-time marking area 320. The computer device receives the panoramic view of the scanned material substrate from the line scan camera and displays it in the panoramic material display area 310. A plurality of pcs particles are distributed in the displayed panoramic material diagram, wherein the defective pcs particles determined in the previous rechecking step are distributed, namely pcs which need to be marked by marking. The real-time marking area 320 is used for displaying the image of the pcs particles to be marked in real time, that is, the pcs particles with defects on the actual material substrate, the displaying is used for conveniently seeing the specific content of the defects, the defective pcs particles can be positioned and marking control can be performed, and the interface is further provided with a marking control 340 for controlling the marking process, for example, laser marking is started after clicking the opening control after selecting and moving to the target pcs position.
And 202, in response to receiving a marking instruction for the target pcs granule image, positioning the corresponding target pcs granule in the panoramic material diagram, and displaying the marking.
Because there are many pcs particles arranged in an array or randomly, the defective pcs usually occupy a small part, and the line scanning camera and the marking process need to position the actual space coordinates after receiving the instruction, and then the line scanning camera and the marking process can be executed. In the same reason, in order to facilitate operators to know the positions of the marked target pcs particles, positioning and marking display are carried out on marked pcs particle images in the panoramic material diagram.
In one possible implementation mode, the labeling frames in the panoramic material map are selected to be cumulative, and each time a pcs particle image is labeled, the distribution condition and the quantity of defect points on the whole material substrate can be visually displayed.
And 203, controlling the marking machine to move to the position of the target pcs particle based on the marked target pcs particle image to perform marking operation, and displaying a marking picture in the real-time marking area.
As shown in fig. 4, when the marking is started, after the target pcs granule image 410 is positioned and marked in the panoramic material image, the position coordinates of the target pcs granule to be marked on the actual material substrate on the whole substrate can be determined, and then the marking component or the mechanical arm of the line scanning camera and the marking machine is controlled to move to the corresponding position for marking, and the marking process scans and transmits the marking picture 420 through the line scanning camera or other components, or displays the marked picture in the real-time marking area 420 after the marking is completed, so as to indicate that the waste marking is completed. The marking screen in fig. 4 has cross marks as marking indicia (marking elements not shown), but may also be marked with letters or other patterns in some other embodiments.
In summary, the application uses the recheck marking system in the production process of the semiconductor chip, after recheck determining the defect pcs particles is completed, a panoramic material display area and a real-time marking area are arranged on the recheck marking interface, and the panoramic image of the complete material substrate scanned by the line scanning camera is displayed through the panoramic material display area. When the marking task is executed, marking and displaying the target pcs particle image to be marked in the panoramic material image, the defect position can be intuitively known, the setting of the real-time marking area is fine-grained to the marking picture, the marking picture of the target pcs is displayed in real time, and the defect and marking content are checked. The two display areas are matched for display to form contrast, so that an operator can conveniently and rapidly execute the marking process, marking efficiency can be improved, and product yield can be improved.
Because the manual marking process requires human intervention, in order to maintain the normal operation of the system without human operation, the modes of the system, namely, the manual marking mode and the rechecking mode, need to be controlled. Based on this, as shown in fig. 3, the present application sets a manual marking control 330 on the recheck marking interface, where the manual marking control 330 is used to control the system to execute the recheck mode or the marking mode.
And after the computer equipment receives a reinspection switching instruction of the manual marking control, namely closing the marking mode, and finishing reinspection operation of the material substrate, directly controlling the marking machine and the line scanning camera to switch the next material substrate to execute reinspection operation.
And after the computer equipment receives a marking switching instruction of the manual marking control, namely starting a marking mode, the system enters the manual marking mode after finishing the rechecking operation of the material substrate, and performs marking operation based on the marking instruction of the target pcs particles.
Optionally, a confirmation box may be popped up after the marking mode is switched and the reinspection is completed, as shown in the upper graph in fig. 5, and after the reinspection of a complete material substrate, the reinspection marking interface displays a manual marking pop-up window 510 to prompt that the manual marking process is about to begin. When the marking mode is turned off and the re-inspection is completed, a re-inspection popup window 520 is displayed at the lower part in fig. 5, which prompts the re-inspection process of other material substrates to be continuously performed.
Since there are many pcs on the material substrate and there may be a plurality of defect points on one pcs, for example, defects may occur on both the front and back surfaces, the marking mode needs to be performed in units of the material substrate, so the present application also intercepts defect images for the defect pcs particles identified on each material substrate, one defect image represents one defect point on the pcs, and all the defect images constitute a defect image set.
When the computer equipment completes the rechecking operation of the material substrate, a defect image list is constructed based on the defect image set identified and intercepted from the panoramic material diagram and is displayed on a rechecking marking interface;
when the computer equipment receives the selection operation of the target defect images in the defect image list, determining target pcs particles needing marking, and executing marking operation on the target pcs particles based on the marking instruction.
Referring specifically to fig. 6, after the pop-up window is finished and enters a marking state, a defect image list 610 is displayed at the reinspection marking interface, and preview images or thumbnails of all defect images cut from the panoramic material view are displayed in the list. When an operator selects a certain defect image, a corresponding target pcs is determined according to the selection operation, and then marking operation is executed. Alternatively, the marking operation may be automatically performed in the list order.
Marking and labeling after the target pcs particles are selected are required to be positioned, marking positioning labels are further included in the defect image list, and the marking positioning labels and the defect images are stored in an associated mode; the marking location label comprises an image coordinate and a pcs number of each defect image in the panoramic material map. Marking the positioning label can number and generate the pcs particles to which each defect image belongs in the defect identification process.
When the computer device receives a selection operation of the target defect image, determining target pcs particles based on the pcs number and marking instructions of the target pcs particle image. And then positioning and labeling display are carried out in the panoramic material map according to the image coordinates. Because the coordinates are established based on the panoramic material map to determine the image size when the defect image is intercepted, the positioning process can directly restore and position based on the coordinates.
Based on the above positioning principle, the process of controlling the marking machine to move to the position of the target pcs particle to perform marking operation is realized by the following steps:
a, establishing a coordinate system based on the position relation between a marking machine and a material substrate;
the position coordinate system can be established by the geometric center or corners of the panoramic material map, and the outline edge coordinates of each pcs particle are determined.
b, calculating the position coordinates of the target pcs particles on the material substrate according to the position relation of the target pcs particle image relative to the panoramic material image;
under the condition of establishing a coordinate system, determining the coordinates of the target pcs particles in the real space mapped by the target pcs particle image according to the proportional relation with the actual material substrate.
And c, controlling the marking machine to move to the position coordinates of the target pcs particles to perform marking operation, and collecting real-time images of the target pcs particles.
The acquired real-time images are transmitted to a computer device for display in a real-time marking area for operator observation.
As mentioned above, because pcs are punched on the material substrate in an array, defects may occur on both the front and back sides, and any defect on either side must be eliminated, otherwise the chip yield is affected. Considering the turn-over operation of the line scanning camera and the marking machine or the transfer platform, the marking is usually performed on one surface, and then the turn-over operation is performed, so that the defect image set of the line scanning camera and the marking machine or the transfer platform should comprise the front and back defect images of the pcs particles in a manner of printing or etching marks on the pcs surface, and the defect images in the defect image list are arranged according to the number sequence of the pcs, so that the back marking after the surface marking is completed.
After the target pcs particles on the material substrate are positioned, responding to the click operation of the marking control, starting to etch the unqualified marks on the target pcs particles, and displaying marking pictures in the real-time marking area.
The method fully considers the marking of the front and back surfaces, avoids the condition that one surface is qualified and the other surface is unqualified and omitted, and improves the detection precision and accuracy.
However, in view of marking efficiency, the method of etching the disqualification mark needs to detect each surface at least twice, and if more than one defect type exists on one pcs, a plurality of defect images with the same pcs number may exist, and repeated marking may occur. Even if there is only one defect per side, the front and back sides need to be marked twice, which generally affects the marking efficiency.
Based on the problems, after the application rechecks all the defect images, combining the defect images with the same pcs number in the defect image set, namely only one defect image is reserved for the defects with the same pcs number in the defect image list, and the reserved images are randomly selected for one, so that only one mark is needed for marking and invalidation. In order to avoid secondary printing or etching, after target pcs particles on the material substrate are positioned, the target pcs particles are directly marked and broken down when clicking operation of marking control is received, namely the material substrate is directly penetrated, secondary detection on the aspects of the target pcs particles is not needed, and packaging operation is not executed naturally when pcs are not detected in the subsequent flow process. This approach is simpler and more efficient than double sided marking.
