    no-suppress press fit pins only Reply

    I know I can create a padstack to accomplish this but, is there any way to select certain pins (press fit) within PCB Editor and attach a no-suppress property to them?

    I'm not sure what you mean by ""press Fit"" pins or how you have managed to utilize a pad stack to get your results.
    If you explain it in more detail as to what you would like to see, I'm might be able to request an enhancement to
    implement what you would like to see.

    According to IPC, components with compliant (press fit) pins should have full padstacks because of the force needed to insert the pins into the hole. If you suppress unconnected pads on internal layers, you could potentially push the barrel out of the hole. The pads act as an 'anchor' for the barrel of the hole.

    What I was asking was, is there any way to 'edit properties' on specific pins within the design and attach a 'no-suppress' property to those pins. As far as I can tell, you can't, but your probably better off modifying the padstack and setting the internal layers to 'fixed' and then refresh padstacks in the symbol. This way you don't have to remember to do it for every design.
