Tab Sub Mark

Tab Sub Mark is a mark to recognize the beginning of FPCB when rigid PCB is used with flexible PCB.

  • FPC Component Definition: Define the FPC components.
    • FPC Component: Select the FPC components from the component group list.
  • Tab Sub Mark Definition: Define tab sub mark.
    • Component Group Selection: If tab sub marks are registered with a component, select a tab sub mark component by selecting it from the component group list.
      • Recognize conductive figure shape as Pad: Recognize as Pad for the conductive shape drawn with Figure shape.
    • Board Figure Geometries: If tab sub mark is drawn with figure geometry in the design, define them with figure geometry’s dimension.
      • Tab Sub Mark Size Ranges: Set the target tab sub mark dimension with width and height.
        • Width: Set the geometry width size or size ranges using the floating value input tool.
        • Height: Set the geometry height size or size ranges using the floating value input tool.
  • Boundary Selective
    • Use Border of Rigid PCB and FPCB: Option to set the boundary as the border between Rigid PCB and FPCB for the clearance checking in the Boundary Checking item.


      Figure 1.
    • Use Copper-Pour on Rigid PCB: Option to check based on Copper-Pour in the Rigid PCB area.


      Figure 2.
      • Top: The checking is based on the Copper-Pour in the Top layer.
      • Bottom: The checking is based on the Copper-Pour in the Bottom layer.
      • Inner: The checking is based on the Copper-Pour in the Inner layer.
  • Checking
    • Check Existence of Tab Sub Mark: Check the existence of the tab sub mark in the design.
    • Clearance between Tab Sub Mark and Board Outline: Check the clearance between the tab sub mark and board outline.
    • Clearance between Tab Sub Mark and Routing Pattern: Check the clearance between tab sub mark and routing patterns.
    • Clearance between Tab Sub Mark and FPC Component’s Pad: Check the clearance between tab sub mark and FPC component pads.
    • Boundary Checking
      • Clearance between Tab Sub Mark and the Border of Rigid PCB and FPCB: Check the clearance between Tab Sub Mark and the border of rigid PDB and FPCB.
      • Clearance between Vias and the Border of Rigid PCB and FPCB: Check the clearance between vias and the boarder of rigid PDB and FPCB.
