Sequential drill output for multi-layer boards?

cheriton

Hi,

 

I have designed a 6-layer board with blind vias and have sent the resulting gerber and ncdrill data to the manufacturer.

 

They have sent it back requesting that the drill files be sequential instead of the default, which seems to be the only way of outputting drill information.

 

They say;

 

HDI is  L1-2,L1-3,L1-4,L1-5, L2-6, L3-6,L5-6, this is not a correct design.

 

1.  We advise customer to change to L1-2,L2-3,L3-4,L4-5,L5-6 sequential drills

 

Is this possible in Circuit Studio?

 

If so, how?

 

Thanks

    It's been a while and still no real solution to this problem.

     

    Does anyone know how to persuade CS to output NCDrill files on a layer-by-layer basis? I believe OrCAD will do this if you select the "By Layer" radio button in the NCDrill output dialog so why is it not possible in CS?

     

    Is it even possible in Designer?

     

    Thanks

    Ok, so it seems that the only way of outputting sequential layer drills in CS is to make every hole a stack of vias in the PCB. This can be a bit tedious, especially with a board with a lot of vias, but it does work.

    I am told that the new version of Altium Designer (V19 I believe) comes with a much improved Layer Stack Manager that shows how the board will be physically drilled, thereby highlighting problems with manufacture.

    Hopefully Altium will update CS to include this rather useful feature.
