SUMMARY

Multilayer PCBs can be designed with varying widths and lengths to create a "shelf" effect, although this is not a standard feature in most layout software. Users have reported challenges in achieving this due to limitations in their design tools. While manufacturers may accommodate custom requests for multilayer stackups, the cost is likely to be higher. Alternative solutions include designing cutout sections or utilizing multiple boards on a single sheet to achieve similar functionality.

PREREQUISITES
  • Understanding of multilayer PCB design principles
  • Familiarity with PCB layout software limitations
  • Knowledge of PCB manufacturing processes
  • Experience with cost implications of custom PCB designs
NEXT STEPS
  • Research advanced features in PCB layout software like Altium Designer or KiCAD
  • Explore custom PCB manufacturing options and their pricing structures
  • Learn about designing cutouts in PCB layouts for functional modifications
  • Investigate techniques for stacking multiple PCBs on a single manufacturing sheet
USEFUL FOR

Electronics engineers, PCB designers, and hobbyists looking to create custom multilayer PCBs with specific geometrical requirements.

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?
