PCB Stackup in IPC-2581 format

Are there any designers who's pcb board house utilizes IPC-2581 for their stackup. I use Allegro PCB Editor for our pcb designs and this editor has the ability to import and export IPC-2581 pcb stackups.

Our board house does not have that capability or they are not willing to use it.

What I have found is that Allegro pcb editor has many formats which can be utilized to import or export files to a board house but if the board house does not use them, what good are they.

Our board house still uses gerbers. I usually send our pcba supplier, gerbers, ODB++ and IPC-2581. In reality I should only have to export an IPC-2581 file and be done but it seems the board houses are still using formats from years ago.

Anyway, if someone knows a board house, either domestic or off-shore, which uses IPC-2581 I would appreciate knowing that company.

Thanks,

I was under the impression that Polar Instruments which most fab houses use does export the IPC2581 cross section so they may well have this tool which they use to calculate impedance. The latest version of Polar should have this capability. It may also be worth looking at this, there is a DFM Partner program integrated with Allegro that may also help you.

I had tried the DFM Partner program two years ago. One company looked promising but after using them twice for designs we did not see the value of using them again. I will look for others, possibly newer partners within that group and reach out to them. Thanks for your information.
