TCP Align Hole

Check the rule of align hole usage.

TCP component is a tape carrier package. TCP align hole is used to fix the TCP components.

The TCP Align Hole dialog contains the following sections:
Figure 1.


  • TCP Align Hole Definition: TCP align hole can be defined with the hole size and distance from the TCP component.
    Figure 2.


    • Definition with Hole Size: Define the align hole with its size. Using the floating value input tool, set the size or range of hole size.
    • Define with Distance from TCP Component Group: TCP align hole should not be apart from the TCP component. They should be placed close together.
      Figure 3.


      • Component Group: Select the TCP component group from the component group list.
      • Maximum Distance: Set the maximum distance between the TCP component and the TCP align hole.
  • Silk Hole Mark Definition: TCP align hole can have two types of shapes for silkscreens: circle and line types. Define the diameter and width/height value for the circle and line types.
    Figure 4.


    • Circle Diameter: Set the circle diameter for the circle type silkscreen.
    • Line: Set the line type silkscreen with its width and length.
      • Width: Set the width of line for line type silkscreen.
      • Length: Set the length of line for line type silkscreen.
  • TP(Test Point) Definition: To check the clearance between a TCP align hole and a test point, set the test point components.
    • TP Component Group Selection: If test points are registered with footprint, select the test point component group from the component group list.
    • Pads’ Diameter in Routing: If test points are used with pads, set the size of the pad diameter.
    • Via’s Diameter: If test points are used with vias, set the size of the via diameter.
  • TCP Align Hole Clearance Checking: Check clearances between the TCP align hole and the TCP component pad/test points in the design.
    Figure 5.


    • Clearance between TCP Align Hole and TCP Pads: Set the clearance value between the TCP align hole and the TCP component pads.
    • Clearance between TCP Align Hole and TP (Test Point): Set the clearance value between the TCP align hole and the test points.
  • TCP Align Hole Checking: Check TCP align hole location and placement.
    • Existence Check for both Edge Components: Check if all edge TCP components have a TCP align hole within the given area. Hole searching area is defined in the TCP Align Hole Definition. If one of them doesn’t have a TCP align hole, it is a fail.
      Figure 6.


    • Silk Hole Mark Alignment with TCP Align Hole: Check if the TCP align hole and silkscreen are aligned along the given axis.
      Figure 7.


      • X: Check if the TCP align hole is aligned with silkscreen along the X-axis. If they are not aligned along the X-axis, it is a fail.
      • Y: Check if the TCP align hole is aligned with silkscreen along the Y-axis. If they are not aligned along the Y-axis, it is a fail.
    • Clearance between PCB Outline to TCP Align Hole Center: Set the clearance value between the TCP align hole and the PCB outline.
      Figure 8.


    • Alignment between Side Edge TCP Align Holes: Check if the side edge’s TCP align holes are aligned with each other along the Y-xis.
      Figure 9.


      • Tolerance: For the two location values, if they are less than the tolerance, PollEx DFM recognizes them as the same value.
      • X/Y: Select alignment axis.
    • Number of TCP Align Holes’ Counting: Check the number of TCP align holes in the design. Choose the maximum/minimum/same value counting condition.
