TCP Pad

TCP component is tape carrier package. Check the specification of TCP component pad (pin).

Figure 1.


  • TCP Component Definition: Define target TCP component.
    • Component Group Selection: Select target component from component group list.
  • TCP Component Area: Define TCP component area.
    • Auto-Detection of Dummy Pad: This menu is automatically detected the TCP pad in the defined area. If there is no component, TCP pad and dummy pad are recognized as TCP pad. If there is a component, it checks using the Expand checking area based on TCP component toward major axis condition.
    • TCP Pad: Define a TCP pad area only with a TCP component.
      Figure 2.


    • TCP Pad + Dummy Pad: Define a TCP pad area with a TCP component and a dummy pad.
      Figure 3.


    • Expand checking area based on TCP component toward major axis: If there is a component other than a TCP pad or a dummy pad between TCP pads in the defined area, this option is used to expand a checking area by the given value from the center point of a TCP component.
      Figure 4.


  • Hatching Existence Check Under TCP Component Area: Checks whether there is hatching or not under the TCP component area.
    • Inner Layers: Search hatching in inner layers, except top and bottom. If there is no hatching, it is a fail.
    • Adjacent Layer: Search hatching on adjacent layer. If there is no hatching, it is a fail. If TCP component is placed on top, PollEx DFM searches second layer to find hatching.
  • Component Clearance: Checks the clearance between the TCP component and another component.
    • Item: Specify the item name.
    • Comp Group: Select component group.
    • Clearance: Set the clearance value between TCP component and specified components.
    • Measure Base: Select measure basement to be used for specified components.
    • Remainder: Set the clearance value between TCP component and components, not defined in table.
    • Exclude Checking for Selected Component Group: Select void-checking component group from the component group list.
  • Checking
    • Silkscreen Existence on Reverse Side of TCP Component: Check whether silkscreen is or is not on the reverse side of TCP component placed layer.
    • Clearance between TCP Component and Vias: Set the clearance value between TCP component and Vias.
      • Measuring Base with TCP Component Area: TCP component measuring base will be TCP component area define at ②, TCP Component Area.
      • Vias only Connected to TCP Component Pads: If this option is checked, PollEx DFM checks clearance only for Vias connected to TCP component pins.
        Figure 5.


    • Clearance between TCP Component Pad and Copper-Pours: Set the clearance between the TCP component pad and copper-pours.
    • Solder Mask Existence Checking in TCP Component Area: Checks if solder mask data is under TCP component area.
    • Allow Patterns Connecting with Pads for One Way: If any pads are connected in both direction, it is a fail.
      Figure 6.


    • Do not allow neighboring NC Pins: If there are neighboring NC pins, PollEx DFM detects them and defines them as a fail.
    • Allow Patterns Connecting with Zigzag Style: For specified TCP component pins, check if their pattern connection has a zigzag connecting structure. If not, it fails.
      Figure 7.


      • Target Pins’ Name: Specify pins names in TCP component.
    • TCP Pad Size
      • Height: Enter a value to check the height of the TCP pad.
      • Width: Enter a value to check the width of the TCP pad.
