Blind via on footprint design

alexspin

Hi all,

we are designing a footprint of a component with an exposed pad that needs some Blind L1 to L2 vias.

How we can specify they in the Package Symbol Design if there is no menu option like we have in the Board Design (Setup->Define BB Vias)?

We have Orcad PCB Designer Standard 17.2 and Orcad PCB Designer Professional 17.4.

Thanks.

    In a Package Symbol, Layout>Connections is used to add connection objects like traces and vias. The Via will need to be designed with the Padsatck Editor and added to the Via List in Constraint Manager, at the top of the list in Physical Constraints makes things easier, and the cross-section will need to be setup to match the board file that the Package Symbol is going to be placed in. Another method is to use through vias in the footprint and then use Tools>Padstack>Replace once the footprint has been loaded into the board file and the cross-section and BB vias have been defined, to replace the through vias of the placed Package Symbol with the required BB vias.
