Screw

Analyze the board to prevent damage.

More detailed information:
  • Screw Definition: Identify the type of screw used depending on ECAD data.
  • Screw Test: Analyze the clearance between screw and solder mask.
  • Screw Slit: Identify the status of the slit around the screw.
    • Use Slit Define Layer: Specify the slit layer.
    • Slit from Hole Center: Analyze the clearance of the slit to the screw hole center.
    • Screw Slit Thickness: Analyze the density of the slit.
    • Slit Direction: Verify the existence of a slit between the screw and recognition component.
    • Boundary Area: Define the region from the screw for component detection.
  • Screw Silk size: Analyze the size of the silk surrounding the screw.
  • Clearance from Component: Analyze the clearance between the screw and the component. Specify the measurement criteria of the screw by screw shape, screw center, or screw hole.
    • Item: Specify the item name.
    • Component Group: Select a component group for analysis.
    • Clearance: Enter the clearance between the screw and the component.
    • Check Base: Select a measurement base.
    • Remainder: Enter the clearance for the remainder that is not specified.
    • Remove fail Result if Slit Exist Between Screw And Component: Ignore the analysis results if the slit exists between the screw and the specified component.
    • Via: Ignore the test results if a via exists between the screw and the specified component.
  • Earth Via Short Test: Analyze the occurring conflict by the screw via between different nets.
    • Allowable Net: Specify the allowed nets.
    • Net Name Filter: Specify the allowed nets by the net name filter.
    • Other Net Clearance: Analyze the clearance between the earth via and the other nets.
    • Detect Pattern Connection on Top/Bottom: Detect if the via is connected to signal nets on the top or bottom layer.
