Rigid-flex PCB design with Xpedition Standard

When innovation demands flexibility, and space is limited, rigid-flex PCBs make it possible to reimagine product design across industries, from miniaturized medical devices to next-gen automotive and aerospace systems. But success in rigid-flex design depends not just on engineering prowess, but also on the right design tools. Xpedition Standard brings powerful, scalable, and intuitive capabilities that help you confidently navigate the unique challenges of rigid-flex PCB design, no matter your team’s size or experience. 

Why should you use rigid-flex PCBs, and why now?

Compact, lightweight, and robust, the core promises of rigid-flex circuits, are driving demand in today’s electronics landscape. These boards combine the reliability and density of rigid PCBs with the mechanical versatility of flexible substrates, enabling electronics to bend, twist, and fit into the tightest spaces without connectors or reliability concerns. 

Yet, designing these advanced interconnects introduces new challenges: adherence to bend radii, careful layer stack-up, specialized material selection, and rigorous data synchronization between mechanical and electrical domains. This is where Xpedition Standard stands apart, simplifying the complex, automating the routine, and helping you achieve first-time-right designs.

Core rigid-flex capabilities in Xpedition Standard

  • Scalable, proven workflow 
    Activate rigid-flex functionality via tokens when you need it – fully integrated in Xpedition’s end-to-end flow with native data continuity, so there’s no tool switching, data translation, or retraining. 
  • Visual stackup zone definition 
    Quickly define and visualize rigid and flex zones. Easily configure copper weights, insulation layers, adhesives, and coverlays in an intuitive stack-up editor. 
  • Automated design rule checks 
    Dynamic rule validation tracks bend radii, layer transitions, trace width, spacing, and component placement, ensuring conformance to manufacturing specs and industry best practices. 
  • MCAD co-design 
    Bidirectional data exchange with leading mechanical CAD tools aligns team efforts and speeds up design validation, minimizing costly late-stage surprises. Siemens NX even allows you to sync up the layer properties, variants, and more. 
  • Real-time collaboration 
    Share stack-ups, designs, and mechanical outlines with stakeholders and manufacturing partners in the cloud, supporting iterative design and faster time to market.
