Problems solved by technology
The existing technology mostly adopts the method of manually drawing the tooling hole of the process edge, but as long as the size of the PCB circuit board is modified, the process edge, TAP and tooling hole must be deleted and redrawn, and manually drawing the process edge, TAP and tooling hole is very time-consuming Inefficiency, manual drawing is not accurate enough, manual drawing is not beautiful, if the appearance of the PCB circuit board is often modified, it will increase the workload of the wiring engineer during the research and development process.

Embodiment 1
[0033] Embodiment 1 of the present invention proposes a method based on the Cadence skill to automatically place the tooling hole at the edge of the process;
[0034] First put the PCB circuit board into the plane Cartesian coordinate system, record the coordinates of the four vertices of the PCB Board outline, and mark the sides of the PCB Board outline according to the coordinates of the four vertices of the PCB Board outline.
[0035] The Tooling hole placement standard is based on the Board outline, that is, the appearance of the PCB circuit board. X is the horizontal coordinate of the plane Cartesian coordinate system, and Y is the vertical coordinate of the plane Cartesian coordinate system. The coordinates of the four vertices of the PCB Boardoutline are (X1, Y1), (X2, Y2), (X3, Y3) and (X4, Y4); L1 and L2 are the two sides of the appearance of the PCB circuit board, then L1 Expressed as [(X1, Y1)(X2, Y2)], L2 is expressed as [(X3, Y3)(X4, Y4)].
[0036] Then, determin...

The invention provides a method and a system for automatically placing a process edge tooling hole based on Cadence skill. The method comprises the following steps: putting a PCB into a rectangular plane coordinate system, recording coordinates of four vertexes of a PCB contour, and marking edges of the PCB contour according to the coordinates of the four vertexes; judging the trend of the edge; in the X-axis direction of the rectangular plane coordinate system, moving towards the interior of the PCB outline by 2 mm, and in the Y-axis direction, moving towards the exterior of the PCB outline by 4 mm, thereby determining the position for placing the positioning hole; and then placing the part with the material number of MH _ H157 _ 48. Based on the method provided by the invention, the invention also provides the system. According to the method and the system, the process edge tooling hole is automatically placed in the program, so that the process edge tooling hole can be rapidly placed, the drawing efficiency is improved, and meanwhile, human errors are reduced.
Description
technical field [0001] The invention belongs to the technical field of printed circuit boards, in particular to a method and a system for automatically placing a tooling hole on a process side based on a Cadence skill. Background technique [0002] Printed circuit board, or PCB (Printed circuit board), is the support of electronic components, in which there are metal conductors as the lines connecting electronic components. On the process side, in order to help complete the production, a part may be added on both sides of the PCB board, and then removed after the production is completed. This kind of plate edge added to assist production is usually called the process edge. Tooling Hole, semi-automatic printing machine or board splitting machine usually needs to use the positioning hole on the edge of PCB process for positioning. [0003] In the process of server research and development, it is inevitable to constantly modify the mechanism board type to meet customer needs....
