Function

Reports thermal spoke (tie) widths that are less than their defined widths.

Measurements are segments describing the spoke width at its thinnest point.

Activation

When layer is negative and thermal pads in layer are flashed (not drawn).

Known Limitations

 

The definition of a thermal pad includes the Tie width.

Thermal Pad Checks

The two categories, Spoke Width and Thermal Connect Reduction, apply only to negative layers and to Genesis Semi-Standard thermal pads. These two categories detect thermal ties that are either completely broken or are clipped by adjacent clearances and thermals.

The two categories report the spoke (tie) width and the overall percentage reduction in thermal pad electrical connectivity. If a thermal has four 10-mil ties, of which two are completely broken, this causes a 50% reduction in thermal connectivity.
