[0002] At present, in the graphic design with process edge design, for the case where the edge of the shape is convex or concave, milling to the process edge and milling a certain distance to both sides can ensure that the shape of the physical board conforms to the data graphics. At present, for what The judgment of milling under certain circumstances, milling under certain circumstances and simultaneously milling the process side on the side is still judged by human eyes, which cannot ensure that the actual object matches the expected design graphics, and the design of the process side is slow, which greatly affects the delivery efficiency and is easy to cause Scrapping, customer complaints, etc.

Embodiment Construction
[0023] The present invention is further described below in conjunction with specific embodiment:
[0024] A method for judging the milling process edge of the circuit board shape, comprising the following steps:
[0025] The first step is to set a zero point and establish a rectangular coordinate system before the graphic design of the shape to ensure that the border lines of the shape are all horizontal or vertical;
[0026] In the second step, the starting and ending points x and y coordinates of the outline border line are stored as the first level of the hash table, and the starting and ending points of each line segment saved in the first level hash table are used as the center to find out the setting The x and y coordinates of the start and end points of other line segments that meet it within the specified tolerance range, and create a multi-level hash table to save the outline drawing designed by the customer. If it is an arc, save the coordinates of the center of the ...

The invention relates to the field of circuit board manufacturing, and relates to a method for judging the milling process edge of the circuit board shape. Before designing the shape graphic, a zero point is set and a rectangular coordinate system is established to ensure that the outline border lines are all horizontal or vertical ;Create and save the outline drawing designed by the customer in the form of a multi-level hash table. If it is an arc, save the coordinates of the center of the circle; traverse the hash table in a circular manner to obtain whether the two ends of all outline border lines need to be milled into part of the process edge, milling It is the judgment result of milling to the side at the same time; according to the judgment of the two ends of all outline border lines, these line segments are connected to form the closed figure of the design outline required for production. The method for judging the milling process edge of the circuit board shape of the present invention has the advantages of fast, automatic, accurate and the like.
Description
technical field [0001] The invention relates to the field of circuit board manufacturing, in particular to a method for judging the milling process edge of the circuit board shape. Background technique [0002] At present, in the graphic design with process edge design, for the case where the edge of the shape is convex or concave, milling to the process edge and milling a certain distance to both sides can ensure that the shape of the physical board conforms to the data graphics. At present, for what The judgment of milling under certain circumstances, milling under certain circumstances and simultaneously milling the process side on the side is still judged by human eyes, which cannot ensure that the actual object matches the expected design graphics, and the design of the process side is slow, which greatly affects the delivery efficiency and is easy to cause Disposal, customer complaints and other issues.
