Abstract
Description

[0002] Vertical continuous copper plating production line (DVCP) is used for electroplating processes on circuit boards. It has good electroplating distribution, hole filling and via filling capabilities, and stable electroplating quality.
[0003] Currently, product defects and equipment defects encountered with DVCP rely entirely on manual visual inspection. Furthermore, the loading, copper plating, and unloading points are located in different areas, making it impossible for a single person to fully monitor all product and equipment defects on the DVCP. The current inspection efforts and persistence are insufficient for continuous identification and detection, hindering timely problem detection and resolution.
[0004] DVCP typically uses a clamping mechanism on a hanger to hold the circuit board material and move the clamped circuit board material to different areas such as the loading position, copper plating pool, and unloading position to perform electroplating processing on the held circuit board material.
[0005] The inventors discovered that if a bracket deforms during the movement of the bracket, the circuit board material held on that bracket may overlap with the circuit board material held on the adjacent bracket, resulting in defects that affect product yield. Summary of the Invention

[0052] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0053] Although the processes described below include multiple operations that occur in a specific order, it should be clearly understood that these processes may also include more or fewer operations, which may be executed sequentially or in parallel.
[0054] Example 1
[0055] The bracket deformation defect detection method provided in this application is specifically applicable to a vertically continuous copper plating production line (DVCP) with two rows of plates. See also Figure 1 The vertical continuous copper plating production line shown is a double-row line. "Double-row" means that the copper plating plates are clamped on both sides of the racks (corresponding to two rows), and the process is advanced synchronously along the production line. The deformation of the racks in a double-row line mainly occurs when the racks deform (or shift) during the process of advancing the plates.
[0056] Please see Figure 2 The bracket deformation defect detection method provided in one embodiment of this application may include the following steps.
[0057] S201. Obtain the rack speed data of the double-row copper plating production line; obtain the first data information monitored by the first ranging sensor and the second data information monitored by the second ranging sensor; wherein, the first ranging sensor is set on the first side of the copper plating production line and the second ranging sensor is set on the second side of the copper plating production line.
[0058] In this embodiment, please continue to refer to Figure 1The rack line speed data refers to the speed at which the rack moves along the production line. The double-row copper plating production line includes column A (side) and column B (side). That is, each rack includes column A (side) and column B (side). In practical applications, a distance sensor is installed on each of sides A and B. For example, if the first distance sensor is installed on side A, the first data information acquired is the data monitored by the first distance sensor on side A. The principle behind the installation of the second distance sensor should be understood similarly, and will not be elaborated here.
[0059] See Figure 3 As shown, Figure 3 This is a schematic diagram of a double-row copper plating production line where any two adjacent racks are in the same row (side). During the copper plating process, there is a certain distance between adjacent racks. (See reference...) Figure 4 As shown, when the ranging sensor is monitoring distance, if a bracket passes through its monitoring area, the sensor will detect a low-level signal due to the bracket's obstruction. Conversely, if no bracket passes through the monitoring area (i.e., from the time the previous bracket has completely passed until the next bracket arrives), the sensor will detect a high-level signal because there is no obstruction. In other words, the first and second data information represent the duration of the corresponding high and low levels.
[0060] S202. Based on the first data information and the hanger line speed data, calculate the first side hanger spacing of the hanger to be tested; based on the second data information and the hanger line speed data, calculate the second side hanger spacing of the hanger to be tested.
[0061] In an optional implementation, calculating the first side bracket spacing of the bracket to be tested based on the first data information and the bracket line speed data includes:
[0062] Based on the first data information, a first high-level duration matching the first side spacing of the bracket to be tested is determined;
[0063] The spacing between the first side brackets of the bracket to be tested is calculated based on the duration of the first high-level signal and the bracket line speed data.
[0064] In this embodiment, the first data information corresponds to the duration of high and low voltage levels in column A of the double-column copper plating production line. The first high-level duration corresponding to side A of the bracket to be tested can be determined by matching the sequence information of the bracket to be tested with the high-level duration in the first data information. Furthermore, the bracket spacing on side A of the bracket to be tested can be obtained by calculating the product of the bracket's linear speed and the first high-level duration.
[0065] In an optional implementation, the spacing between the first side hangers of the hanger to be tested is calculated using the following formula:
[0066] L An =1 / 60*k*t An ;
[0067] Among them, L An The spacing between the A-side hangers of the hanger n to be tested is in mm; k is the hanger linear speed of the copper plating production line, in m / min; t An The duration of the high-level signal on side A of the mounting bracket n to be tested, in milliseconds.
[0068] In an optional implementation, calculating the second side bracket spacing of the bracket to be tested based on the second data information and the bracket line speed data includes:
[0069] Based on the second data information, determine the second high-level duration that matches the second side spacing of the bracket to be tested;
[0070] The second side bracket spacing of the bracket to be tested is calculated based on the duration of the second high level and the bracket line speed data.
[0071] In this embodiment, the second data information corresponds to the duration of high and low levels in column B of the double-column copper plating production line. The second high-level duration corresponding to side B of the rack to be tested can be determined by matching the sequence information of the rack to be tested with the high-level duration in the second data information. Furthermore, the rack spacing on side B of the rack to be tested can be obtained by calculating the product of the rack line speed and the second high-level duration.
[0072] In an optional implementation, the spacing between the second side brackets of the bracket to be tested is calculated using the following formula:
[0073] L Bn =1 / 60*k*t Bn ;
[0074] Among them, L Bn The spacing between the brackets on side B of the bracket n to be tested is in mm; k is the linear speed of the brackets in the copper plating production line, in m / min; t Bn The duration of the high-level signal on side B of the mounting bracket n to be tested, in milliseconds.
[0075] Furthermore, it's important to note that the hangers typically also have anti-collision targets, which are considered part of the hanger as a whole in this solution. However, in practical applications, the length of the anti-collision target needs to be reduced by twice to obtain the actual hanger spacing. The subsequent threshold setting can also be determined based on the length of the anti-collision target. That is, if the hanger spacing after removing twice the anti-collision target length is used as the basis for judgment, then the range of the first threshold mentioned below should be the original threshold minus twice the anti-collision target length. The specific logic will not be elaborated here.
[0076] S203. Based on the spacing between the first side brackets and the spacing between the second side brackets, and combined with a preset threshold, determine whether the bracket to be tested has a deformation defect and generate a judgment result.
[0077] In this embodiment, it is typically necessary to first determine the spacing between the first and second side brackets. If the spacing on one side exceeds the corresponding preset range, it indicates that the distance between that side of the bracket and the adjacent bracket is unreasonable. This could be due to bracket deformation or other reasons, requiring staff to investigate the cause on-site. If the spacing on both sides is within a reasonable range, the difference between the two side bracket spacings and a preset threshold can be used to determine if the bracket has any deformation defects.
[0078] In this embodiment, by acquiring the line speed data of the racks on the double-row copper plating production line and the monitoring data from the distance sensors located on both sides of the racks, the rack spacing can be determined from the monitoring data. Furthermore, by combining the rack spacing on both sides with a preset threshold, a judgment result is generated to determine whether the racks have deformed. This method effectively monitors the double-row copper plating production line, promptly detects rack deformation defects, facilitates timely problem handling, avoids material stacking defects, and improves the product yield of the double-row copper plating production line.
[0079] In an optional implementation, the step of determining whether the bracket to be detected has a deformation defect and generating a determination result based on the spacing between the first and second side brackets and a preset threshold includes:
[0080] Determine whether the spacing between the first side brackets is within the first preset threshold range;
[0081] Determine whether the spacing between the second side brackets is within the first preset threshold range;
[0082] If it is determined that the spacing of the first side bracket is not within the first preset threshold range, a defect identification result for the spacing of the first side bracket of the bracket to be detected is generated.
[0083] If it is determined that the spacing of the second side bracket is not within the first preset threshold range, a defect identification result for the spacing of the second side bracket of the bracket to be detected is generated.
[0084] In this embodiment, by setting a first preset threshold and comparing it with the spacing of the first and second side hangers, it is possible to identify whether there are corresponding hanger spacing defects on the double-row copper plating production line. This helps on-site inspectors to promptly identify and address problems, ensuring the normal operation of the double-row copper plating production line and improving its production efficiency. This further improves the product yield of the double-row copper plating production line.
[0085] In an optional implementation, the step of determining whether the bracket to be detected has a deformation defect and generating a determination result based on the first side bracket spacing, the second side bracket spacing, and a preset threshold further includes:
[0086] If it is determined that both the spacing between the first side bracket and the spacing between the second side bracket are within the first preset threshold range, then the absolute value of the difference between the spacing between the first side bracket and the spacing between the second side bracket is calculated.
[0087] Determine whether the absolute value of the difference is within the range of a second preset threshold;
[0088] If the absolute value of the difference is determined to be within the range of the second preset threshold, then it is determined that the bracket to be tested does not have deformation defects.
[0089] If it is determined that the absolute value of the difference is not within the range of the second preset threshold, then it is determined that the bracket to be tested has a deformation defect.
[0090] In this embodiment, the judgment is made by the absolute value of the difference. When the absolute value of the difference exceeds a second preset range, it indicates that the difference in the distance between the two side brackets is too large, meaning the bracket has undergone a significant offset (deformation). This method can identify whether the brackets on the double-row copper plating production line have deformation defects, thus helping on-site inspectors to promptly identify and address problems, ensuring the normal operation of the double-row copper plating production line, improving its production efficiency, and further increasing the product yield of the double-row copper plating production line.
