Dynamic Package Height

Joewi
Joewi over 5 years ago

Is there a way to set a dynamic package height for a symbol that would take into account the stackup thickness?  We have several configurations where different stackups are required but the allowable insertion space doesn't change.  Unfortunately, the backside of the PCB has multiple height restrictions, so a blanket calculation and change would be tedious. 

Thanks

    I believe component height DRCs are intended to measure the height of the component, not involve the thickness of the stackup.

    I have never heard of layout software that took the board thickness into account.  

    Allegro and Orcad can check for interference between a board assembly and an imported enclosure step file.  Can  you use this updated method?

    Missing Step models.  Quite familiar with that.

    WFH to study Solidworks with an online service called "Solid Professor".  Just have to hide this from our "fake-swamped" MEs.
