        Dome Sheet Guide Hole
        Check the dome sheet guide hole specification, clearance with component, and the number of holes.
        FPC Dummy Pad
        Check the specification for Flexible Printed Circuit (FPC) connector pads.
        Key Pad
        Check the key pad design and via usages.
        LED
        PollEx DFM searches for resisters near Light Emitting Diode (LED) components.
        Symmetry Arrangement of Component
        Verifies the position of the component and that the net connected to the pin is designed symmetrically, because this design combines two PCBs with the symmetrically placed components in each design.
        TCP Align Hole
        Check the rule of align hole usage.
        TCP Bonding Mark
        Check the rule of TCP bonding mark design.
        TCP Dummy Pad
        TCP component is tape carrier package. TCP dummy pads are designed between TCP components. It could be designed with footprint or can be replaced with routing patterns.
        TCP Pad
        TCP component is tape carrier package. Check the specification of TCP component pad (pin).
        Text Existence
        Check existence of specified text string in the design.
        Undefined Component
        This checking item finds components that do not belong to Component Class, Group, and Measure Base in the PollEx DFM Rule settings.
      - 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.

FPC Dummy Pad

Check the specification for Flexible Printed Circuit (FPC) connector pads.

FPC connector is the components in FPCB to connect PCBs.

The FPC Dummy Pad dialog contains the following sections:

FPC Component Definition: Define the FPC connector component.
- FPC Component Selection: Select component from the component group list.
Checking: Check FPC dummy pad distance and number of distances in each side.
Figure 1.
- Distance between Dummy Pad’s Edges: Set the distance value between dummy pads. If distance is not matching with the given value, PollEx DFM defines them as fails.
- Minimum Number of Dummy Pad in each Side: Set the minimum number of side dummy pads.
