        Check the design boards origin points.
        Cutting Region
        Check the cutting holes design rule, location, and clearance to other objects.
        Data Existence
        Verify the certain layers existence and data existence on the layer.
        Dummy PCB
        Verify the copper existence in the dummy area of an arrayed board.
        Fiducial Mark
        Verify that fiducial marks are designed correctly on the paneling board.
        Guide Hole
        Validate the guiding hole in the PCB's design.
        Guide Line
        Check item for the soldering guide line width and the drawing layers clearance with other geometries or objects.
        Jig Hole
        Detect the JIG hole that drives in Jig machine.
        Label Box
        Check the label box existence or size.
        Layer Stack-up
        Check the Board, Copper, Dielectric, Solder Mask Thickness.
        Min Silk Width
        If silkscreen data is drawn with a thin width, it’s difficult to recognize it.
        Missing Hole
        Often, Missing Hole is also referred to as Cutting Region.
        PCB Mark
        Recognize a single board by machinery and check the rules about PCB marks.
        PCB Outline Sharp Angle
        Analyze the sharpness of the PCB outline.
        PCB Outline Spacing
        Verify the clearance between a single board outline and various objects.
        PCB Outline Width
        Check the width of the PCB outline.
        Routing Slit
        Check the rule for the routing slit on the PCB design.
        Solder Mark Violation
        Verify the solder mask is in the PCB design and if it overlaps with routing patterns.
        SMT Direction Mark
        SMT direction marks placement checking item on special layer.
        Sub Board Misarrangement
        Check if single boards have the same distance to panel or have placing type.
        Sub Board Placement
        Check the sub-boards placement order and soldering direction.
        V-Cut
        Check the V-Cut and its region in the panel board.

SMT Direction Mark

SMT direction marks placement checking item on special layer.

The SMT Board Misarrangement dialog contains the following sections:

SMT Direction Mark Definition: Choose a layer where the SMT mark is located.
- Layer Selection: Select the layer from layer list.
- Component Group
  - SMT Direction Mark: Select the SMT direction mark from the component list.
Checking
- Placement Layer : Check the SMT direction mark placed layer.
  - Same on Specified Component : Check the same layer as the specified component, if the SMT Direction Mark does not exist in the same layer, it is fail.
    - Specifying Component : Select specific component.
    - Exceptional Component : Exclude specific component.
  - Top : If the SMT Direction Mark does not exist in the Top layer, it is fail.
  - Bottom : If the SMT Direction Mark does not exist in the Bottom layer, it is fail.
  - All : If the SMT Direction Mark does not exist in the Top and Bottom layer, it is fail.
- Mark Direction
  - Relative Direction
    - Horizontally Long Board : Define SMT direction Mark on a horizontally long PCB design.
    - Vertically Long Board : Define SMT direction Mark on a vertically long PCB design.
    - Square Board : Define SMT direction Mark on square PCB design.
  - Absolute Direction : Select SMT direction Mark without considering relativity.
  - Insertion Mark : Check if the Insertion Mark (Pusher Mark) exists on the opposite side of the SMT Direction Mark.
  - Mirrored Direction on the Bottom Layer : When selecting the check box, the SMT direction Mark of the bottom layer becomes mirrored with the top layer.
