Thermal pad connections trace width

LSAUGE
LSAUGE over 3 years ago

Hello,

Is there a possibility to change the trace width of the thermal pads connections without changing it for all the traces in the layout ?

For example, I'd like the min trace width to be 0.1 mm but the thermal pads connections to be 0.2 mm. But when I put 0.1 mm as min trace width in the contraints manager, the thermal pads connections automatically switches to 0.1 mm.

Best regards,

Loïc Sauge

    You could try using a Constraint Region. Watch Cadence PCB Constraint Regions Rules By Area - YouTube

    Sure

    This can be done selectively at the actual pin level.

    Try the following, In the find filter check pins. Hover over your pin of interest so it highlights then right-click and select "property edit"

    In the list choose "dyn_fixed_term_width" and enter a value you wish to use for the connection.

    In addition it is also possible to change both the dyn clearance and the thermal connection type too.
