PCB Layer Stack Manager

[ronbonne]

We do a lot of work with Aluminium IMS PCBs, but the layer stack manager in Fusion Electronics has no support for it. We are designing a board using the below stack and the layer stack manager won't let me create this in any form (even with synchronization turned off, it insists I have both a top AND bottom silkscreen/soldermask and it won't let me place a core below a prepreg/dielectic. I know this does not matter when generating gerber files, but it does matter for controlled impedances, thermals, and the 3D representation of the PCB, all of which use the layer stack. Any suggestions are welcome.

Hello @ronbonne ,

I hope you're doing well. Thanks for sharing the stackup, you are correct we don't currently support this type of stackup. The 3D PCB won't be able to support it either currently so the best you can do is what you have already mentioned. Treating it like a 2 layer PCB and generating gerbers for it.

I'll share this request with the developers for future improvements.

Let me know if there's anything else I can do for you.

Best Regards,

Thanks Jorge. I realize the specific stackup I am asking for is somewhat exotic, but even support for generic IMS PCBs (eg. single layer) would be greatly appreciated. I read in the forums a request for such a feature has been out there for a while.

Hi @ronbonne ,

I hope you're doing well. I've added your comments to the existing ticket. It has been a standing request for some time, there's a lot to prioritize but thank you for your comments since it helps drive home the need for this.

Let me know if there's anything else I can do for you.

Best Regards,
