Can Multilayer PCBs Create a "Shelf"?

[zandroid]

Can multilayer PCB have different width and/or length layers to create a "shelf"?

I am in need of creating a 4 layer PCB stackup, but I need to have one of the PCB different width and length to create a "shelf" so to speak. Has anyone heard of doing such a thing? My layout software doesn't give the ability to create different size layers of a multilayer stackup.

Thanks in advance for any expertise!

I have not (I have designed and ordered several PCBs in both a professional and hobbyist capability from a number of different vendors).

I'm not sure how hard it would be to get a manufacturer to do it, obviously if you've got enough cash someone will figure it out, but I would suspect it wouldn't be cheap!

Why do you need a "shelf" anyways?

can't you just design a cutout section ? put two or more boards onto one sheet?
