Circuit board profile process edge milling judgment method

Abstract

The invention relates to the field of circuit board manufacturing, and provides a circuit board profile process edge milling judgment method. Before a profile graph is designed, a zero point is set, and a rectangular coordinate system is built so as to guarantee that all profile frame lines are horizontal or vertical; the profile graph designed by a client is stored in the form of a multi-level hash table, and a circle center coordinate is stored if the profile is in an arc shape; traversal is conducted on the hash table in a circulation mode, and results for judging whether partial process edge milling need to be conducted on the two ends of all the profile frame lines or not and for judging whether milling needs to be conducted towards side edges at the same time or not in the milling process are obtained; line segments are connected together according to the judging results of the two ends of all the profile frame lines to form a designed profile closed graph required by production. The circuit board profile process edge milling judgment method has the advantages of being 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. Contents of the invention [0003] The invention provides a met...
