      - FPCB
        FPCB is excellent for development of electronic components as electronic appliances are becoming miniaturized and lightweight.
      - Ground Wall
        Check the clearance for an area affected by ground wall.
      - Package
      - PAD
      - Pattern
        1 Pin Nets
        Scan the Net List on PCB data and detect the net which is connected to only 1 pin.
        Acute Angle
        Check the Angle formed by objects and segments
        Connected Pad
        This section examines whether the ratio of the connection of pad and pattern is outside the defined value.
        Connected Pattern Direction
        Check the pattern opposite routed directions.
        Copper Boundary Width
        Checks the outline width of copper-pour data.
        Crack Pattern
        In almost cases, pattern connected to pin should be thicker than a certain width and should keep its thickness within a certain distance.
        Intermediate Pattern
        Check the thickness which deviates from the pad edge.
        Keep Out Pattern
        Check routing status from certain components.
        Lines Between Two Pins
        Check the number of patterns, the distance between pins, and the distance between pin and patterns.
        Mechanical Short
        Check an electrical short of different routing patterns.
        Min Same Net Spacing and Width
        Check the minimum spacing between copper objects and the copper width.
        Minimum Width
        Check the pattern minimum width.
        Net to Net
        Check the clearance between net to net.
        Object to Object
        Wiring designed by Artwork mode is recognized as objects and not nets, but it is required to keep the clearance between object to object.
        Pad to Net
        Check a component pin clearance with various objects on design.
        Silver Paste TH PCB
        In the case of a PCB design designed to use silver paste, it can be checked with the related design rule here.
        Unrouted Net
        This item can detect the dangling net and check the connected net to see if the net is completely connected to pin or not.
        Void Coverage
        Check the void coverage with hole placed to copper plane.
      - Placement
      - Test Point
        Verify if the clearance between test points and other objects follow specifications and if the test points contain text.
      - Test Point2
        Analyze the clearance between a test point and each component on a board.
      - Tooling
      - Underfill
        Find and examine underfill areas in BGA-type components.
    - Result
    - Lock Input Setup
      Lock the DFM input rule file (*.DFMI) to prevent any modifications from others.
  - Logic DFE
    PollEx Logic DFE is a toolset that checks electrical validity and standardizing of schematic design.
  - Technical Cleanliness
    PollEx Technical Cleanliness (TC) is an optional module of the PollEx PCB and a reliability analysis tool set for hazardous areas on a PCB design, using its micro particles.

Mechanical Short

Check an electrical short of different routing patterns.

In case of objects, via, pattern, or NC pins which do not belong to a net, have connection with two different routing patterns.

Checking
- Target Object Definition: Define target objects.
  - Non-Electrical Via: Vias which do not belong to any nets will be target objects.
  - Net Name un-assigned Pattern and Polygon: Pattern or polygon which is not electrical net assigned will be target object.
  - NC Pin: NC pins will be target objects.
