Adding a free via matrix array in PCB Editor

KEN13

Good morning all,

     In Orcad Layout you could add a free via matrix array when you needed to heatsink a component pad/copper area from the top layer to the bottom layer.  Can this be done in PCB Editor and how?  Thank you for any help.

Ken

    Add a via connecting ther shapes together that you require, then Edit - Copy and set the copy mode in the options menu (rectangular or polar) and qty in x and y, also make sure retain net of via is checked, then pick the via you wish to copy and pick an origin point and you have the array.

    You can also use the Manufacture - Thieving command and add the thieivng vias across the board then once there use Padstack replace and replace the surface mount thieving via with an actual PTH one.

    Hi Ken,

    Allegro PCB Editor has the ability to do this via the Place Menu (Place > Via Arrays) but you will have to use an Allegro PCB Designer license or higher. From what I can tell, this functionality is not available in any of the OrCAD PCB Editor licenses.

    Hope this helps,

    Hi Mike,

    Since Orcad PCB designer standard 17.2 doesn't have PLACE>VIA ARRAYS option, what would be the best method to have Via stitching and Ground Shielding?

    See my original comment in this post (above) using either Copy or Thieving
