        AOI-AXI
        Checks components on the board that obstruct the field of vision by the height of specific parts.
        Component Count
        Calculate and display the number of placed components.
        Component on Component
        Verify the specified components placement on the board.
        Component Placement
        Define components that must be placed on a specified side of the board and locate components violating specifications.
        Component Placement Angle
        Manage the angle of the component for efficient mounting.
        Mark Placement
        Verify the placement of a specified board mark. For example, a lead-free mark, fuse mark, and so on
        Placement
        Analyze the location and orientation of a specified component on the board.
        Placement at Reverse Side
        Verify if components are viable for reverse placement on the same board layer.
        Placement Keepout
        Segment specified board areas to exclude selected objects. For example, objects such as a via, pattern, solder mask, and so on.
        Prohibited Component
        Analyze the board and locate components that are no longer available for use.
        Standard Component
        Compare the part lists between the standard part library and the used components from the design.
      - Test Point

Component on Component

Verify the specified components placement on the board.

The specified component is located above or below the coupled components.

More Detailed information:

Add Check Item: Enter the number of items in the box and click Add Check Item to add items for verification.
Except Unclassified Component to Below Comp Group: Exclude components absent from the Below Component Group window from verification.
Check Item: Specify the item name.
Upper Component Group: Enter the group of components located above the component selected for verification. For example, enter Shield Can.
Below Component Group: Enter the group of components located below the component selected for verification.
Upper Component Count: Verify the number of upper components. Over case is detected as an error.
Overlap: Place an overlapped case on a specified component. For example, an eyelet is placed on another DIP type component.
Pin MisMatch: Detect a mismatched pin location between the upper component and the below component. If the pin location is mismatched, it is detected as an error.
Minimum Pin Match: If there is at least one pin location between the upper component and the bottom component matched, it is detected as pass.
POP(Package on Package): Verify the first pin mark on components used for Package on Package assembly.
Layer: Define the layer of the first pin mark in the POP feature.
Tolerance: Enter a tolerance for the verification of the first pin mark in the POP feature. If the first pin mark is within the entered tolerance, it passes the detection.
