Description

Technical Field

[0001] The present invention relates to the technical field of printed circuit boards, and particularly to a method, device, equipment and storage medium for controlling the forming of SET panels of printed circuit boards. Background Art

[0002] In actual production, for some products with multiple SET panels in printed circuit boards, during forming, there will be a phenomenon that the outer dimensions of the SET are qualified, but the distances from the same position inside the SET to the board edge are unqualified. The appearance of this phenomenon is because during forming, the milling tape is generally made using the target hole expansion and contraction coefficient measured during press lamination and drilling. However, after drilling and before forming, processes that affect the expansion and contraction of the board, such as plasma, electroplating, outer layer etching, and solder mask baking, will be experienced. For products with multiple SET panels, they may undergo some irregular deformations. The expansion and contraction are not the central tensile deformation after press lamination. There may be various translational deformations in addition to the central tensile deformation.

[0003] Currently, for this problem, the common solution is: re-measure the target holes or the outer layer pattern to calculate the actual expansion and contraction, then re-center the stretch data to produce the milling tape, and then check whether the milling tape needs to be further adjusted in combination with the first-piece results. However, this method still cannot effectively match all the above deformation situations, resulting in serious scrapping of the panels. Summary of the Invention

If the differences in the first direction and the second direction between the actual coordinates and the standard coordinates of the four target points of the actual SET panel are equal, adjust the milling tape data by means of data translation according to the standard coordinates of the four target points of the actual SET panel.

[0088] Exemplarily, whether (x ′ 1 - x1), (x ′ 2 - x2), (x ′ 3 - x3) and (x ′ 4 - x4) in the X direction are equal, and whether (y ′ 1 - y1), (y ′ 2 - y2), (y ′ 3 - y3) and (y ′Check whether the differences in the X and Y directions between the actual coordinates of the four target points of the actual SET panel and the standard coordinates are equal.

Exemplarily, let the difference in the X direction be a and the difference in the Y direction be b. The coordinate to be adjusted is the coordinate (Xset1, Yset1) of a single SET positioning hole inside the standard graphic. Then the adjusted coordinate on the actual board is (Xset1 + a, Yset1 + b).

[0105] Exemplarily, when the vector rotates around any point (x0y0), first translate the point (x1, y1) so that the rotation center (x0y0) becomes the new origin. The translation is achieved by (x1 - x0, y1 - y0). Let the rotation angle be θ1, and the rotated coordinates be (x′1, y′1), where x′1 = (x1 - x0)cosθ1 - (y1 - y0)sinθ1 y′1 = (x1 - x0)sinθ1 + (y1 - y0)cosθ1.

If all the target points coincide, no adjustment is needed. If at least one target point does not coincide, the method of data stretching is used to adjust the milling tape data so that the target point coordinates of the actual SET puzzle board are aligned with the standard coordinates. Calculate the vectors of different sides formed by the four target points in the standard graph and the actual SET puzzle board of the SET puzzle board respectively. According to the vectors of different sides of the four target points in the standard graph and the actual SET puzzle board, calculate the intersection coordinates of the vectors on the two-dimensional plane. Use the cosine formula of the vector to calculate the included angle between the vectors of different sides of the standard graph and the actual SET puzzle board according to the intersection coordinates. According to the calculated included angle, use the rotation matrix to calculate the new coordinates of the standard coordinates of the four target points in the standard graph of the SET puzzle board after stretching and rotation. Determine the calculated new coordinates as the target point coordinates in the stretched milling tape data.

Translate the target point to be translated so that it coincides with one of the target points in the standard graph of the SET puzzle. Calculate the differences in the first direction and the second direction of the target point to be translated before and after translation. According to the calculated differences, synchronously translate the other three target points of the four target points of the actual SET puzzle and output the milling belt 1 according to the differences in the X and Y directions. After completing the data translation, if adjustment is still required, data stretching is performed. Calculate the vectors of different sides formed by the four target points in the standard graph of the SET puzzle and the actual SET puzzle respectively. According to the vectors of different sides of the four target points in the standard graph and the actual SET puzzle, calculate the intersection coordinates of the vectors in the two-dimensional plane. Use the cosine formula of the vectors to calculate the included angle between the vectors of different sides of the standard graph and the actual SET puzzle according to the intersection coordinates. According to the calculated included angle, use the rotation matrix to calculate the new coordinates of the standard coordinates of the four target points in the standard graph of the SET puzzle after stretching and rotation. Determine the calculated new coordinates as the target point coordinates in the milling belt data 2 after stretching. According to the milling belt data 2 after stretching, adjust the design requirements in the production process to produce the SET puzzle until the predetermined accuracy requirements are met. It solves the problem that the external dimensions of the SET puzzle are qualified but the distances from the same position inside the SET to the board edge are unqualified. It achieves the effects of improving the production control accuracy of multi-SET puzzle products, improving production efficiency, saving production costs, and reducing the scrap rate of board parts.
