PCB Mark

Recognize a single board by machinery and check the rules about PCB marks.

The PCB Mark dialog contains the following sections:
  • PCB Mark definition: Define the PCB marks in the design.
    • Component Group Selection: If the PCB mark is designed with a component, specify the component group.
      • Mask(S/R) Size (SS): Set the PCB mark with the outer mask size.
      • PAD Size (PS): Set the PCB mark with the inner pad size.
      • Recognize conductive figure shape as Pad: Recognize an object that is drawn with the figure shape in the conductive layer as a Pad.
    • Board Figure Geometries: If the PCB mark is defined with board figure geometries, specify the size of the pad and mask sizes.
      • Mask1(S/R) Size (SS): Set the PCB mark with the outer mask size.
      • PAD1 Size (PS): Set the PCB mark with the inner pad size.
      • Mask2(S/R) Size (SS): Set the PCB mark with the outer mask size.
      • PAD2 Size (SS): Set the PCB mark with the inner pad size.
        Figure 1.


  • Except checking PCB Mark:
    • Major Axis Length <: Exclude the PCB Mark when the PCB major axis is shorter than the setting value.
  • Checking
    • Copper Existence Check: Use PollEx DFM to check copper-pours at the same region of the PCB mark. On the same layer, copper-pour cannot be overlapped with the PCB mark, but on other layers, there should be copper-pour around the PCB mark.
      Figure 2.


    • Placement: Check the placement status of the PCB mark.
      • PCB Mark Placed Side(s): Select the layer and use PollEx DFM to check the PCB mark.
        • Count: Count the maximum, minimum, or exact number of PCB Marks in the design.
      • Exceptional PCB Mark Component: Set the void-checking component group.
    • PCB Mark Existence:
      • Normal Checking:
        • Number of PCB Region: Give the number of regions to divide the PCB.
        • PCB Mark Existing Region: Set the region where the PCB mark is located..
          Figure 3.


      • Detail Checking:
        • The Long Size of PCB: Input the value of a long size range of the PCB.
        • Criteria for Count: Select an inequality sign for checking the PCB mark count.
        • Minimum Count per Area: Input the minimum number of PCB Marks that should exist in the checking area.
        • PCB Mark Existing Region: Set the region where the PCB Mark is placed.
          Figure 4.


        • Number of PCB Region: Set the number of regions to divide the PCB.
        • PCB Mark Existing Region: Set the region where the PCB mark is located.
    • Silkscreen Overlapping: To check the PCB mark overlap with silkscreen, set comparing GERBER layer for the top and bottom.
    • Clearance Checking:
      • Component: To check the clearance between the PCB mark and components, set the clearance value.
      • Route Patterns: To check the clearance between the PCB mark and route patterns, set the clearance value.
      • Copper-pour: To check the clearance between the PCB mark and copper-pour, set the clearance value.
      • Via: To check the clearance between the PCB mark and vias, set the clearance value.
      • Board Outline: To check the clearance between the PCB mark and the board outline, set the clearance value.
