PCB Shape is Not Designed To Cover Small Circles and Grooves

PCB proofing recently received frequent feedback from customers to dig wrong holes, shape cut large or small, after understanding the document design of large circle wrapped small circle (large hole wrapped small hole), two contour lines.

1. wrong design

1.1. Big circle covers small hole

1.2. Big circles in small circles

1.3. Two contour lines

2. correct design

2.1. remove the ring that does not need to be formed, and retain the ring or hole that needs to be formed

2.2. Double click the line or circle (shape) that does not need to be formed as shown in the following figure, the KEEP-OUT (make it outside) check selection will play a prohibition role, and it will not be used as a forming hole.

2.3. do not want to check the forbidden, and worry about deleting the forbidden wiring circle, proofing does not meet the structure of the re-optimization file, not to draw a circle, in response to this problem, you can copy the design of the file in another disk, the unnecessary circle deleted to the factory plate. The original file is saved, and there is a need to modify the direct lift optimization.

Note: Wiring design screw hole elliptic slot hole and plate frame line do not part in the mechanical layer, part in the KEEP-OUT layer, please unify to a layer design, do not make mixed, let others guess. In response to such problems, we prefer a layer of data forming of the board and frame line (the board and frame line must be cut and formed), such as the production of forming error slot leakage hole PCB circuit board processing plant is not responsible!
