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.
