TH pin does not connect to a shape of the same assigne net

KobiC

I have 3 different TH components that share the same net "AC_N". 

2 components pins connects well to the shape on top layer "AC_N", while the third does not connect.

The global dynamic params are set well to all the other pins, except this.

Any thoughts?

Thanks!

    One comment for this problem - the other pin of that same components does not connect to shape as well. 

    Can it be related to the component assembly properties?

    Check for properties on the pin.  i.e. - Thermal properties or shape connect.

    This happens to me a lot for other designs footprints/schematics - the build a footprint with property fields set with wrong settings.

    I am assuming this is a dynamic shape -

    Once the Properties are set try updating shape:

    Global Dynamic Shapes Parameters - Update to Smooth -> Force Update

    Note: the thermal spokes may not be forming because the shape does have enough room around the pin, can you grow the shape a little in width by the pin?

    Also try:

    Dyn_Thermal_Con_Type = 8_WAY

    I wonder if it's related to the dra file of that specific part, or maybe to the constraint manager.

    I have another 1 more component in my circuit that has the same problem.

    Still not connecting.. Disappointed

    A couple other things to check

    1. Are the pins outside of the Route Keepin/All Shape? ( Long shot but had to ask :-) )
      • Thermal Clines create DRCs outside the Keepin so they would not be generated.
    2. Is there a Route Keepout Shape with the SHAPES_ALLOWED Property over the pins?
      • SHAPES_ALLOWED Property on Keepout shapes would allow Dynamic Shapes but not the Thermal Clines.

    Hope this helps,

    Try this -

    Edit the pin and set the DYN_THERM_CON_TYPE to CDN_All and "Full contact" and see if it pours over the pad.

    If it does, then follow Mike's suggestion

    If it won't pour over it's not the pad issue, it's more likely the shape parameter. (e.g. if you make the shape larger will it flood/spoke?

    Good day.
