Maximum Package Height

BuddSw
BuddSw over 14 years ago

I am using Allegro PCB Editor 16.3.  Although I have used this product for a while I've never needed to add Maximum Package Height as something to flag using DRC.  I've looked in the documentation and the only constraint-setting information I can find is for spacing/width/pairing type stuff.  Where can I find the documentation to set up maximum height constraints?  I know I can manually check each package on the board for it's Max Height property that is far from ideal.

 I will be grateful for any insight that can be given.

    Shape - Circular, set the class/subclass to Package Geometry/Place_Bound_Top (in the fold out Options menu on the right hand side of the screen) and then draw the circle you want. If your using 16.6 look at the Options menu and you can set the size you require and then Place Circle option and it will be attached to your mouse ready to place.

    Dear  BuddSW ,

    This may not be the correct procedure but its simple way I follow  when I have a height restriction in some area during placement  . Draw package keepout in the area where you have a height restriction & assign the height limit for that shape( say 100mils) , when you view this in 3D veiw you will notice if any part placed which height is more than 100mil will protrude  out as shown in image, but the issue here is you get CC error for all part placed inside that keepout 

     

    Regards,

    GK

    OK, for a keepout, Package_Height_Min is going to be 0 if you don't specify a value, that's going to be the board surface, so any parts placed within the boundary of that shape will cause a DRC. You increase the Package_Height_Min property of a Package Keepout to raise it off the board surface to allow parts with a height of less than, or equal to, the Package_Height_Min to be placed there without a DRC, parts with Package_Height_Max of greater than the Package_Height_Min of the Keepout will generate a DRC.

    I know this is an old thread, but I felt the need to say THANK YOU. There are a lot of questions answered here and other forums at a level that is nigh impossible for a beginner to understand, but this one is golden. Short, simple, and clear, this is exactly what I needed.

    Edit: Added quote for clarity
