PCB-First vs Enclosure-First Design

I

intellexion

Briefly describe what it's like to design a complete product in Flux. Help me understand what the PCB-first and enclosure-first design workflows are like to work with.

flux

Designing a complete product in Flux means developing the electronics and mechanical design together—schematic, PCB, enclosure, connector access, mounting, and manufacturing checks—with iteration as constraints emerge.
  • PCB-first: Start with the circuit, then size and lay out the board, and build the enclosure around it. This works well when electronics drive the product; the trade-off is that the case may become larger or less ergonomic.
  • Enclosure-first: Start with the product’s shape, handling, mounting, and external interfaces, then fit the PCB inside. This works well when size or appearance is critical; the trade-off is tighter placement constraints and potentially more electronics rework.
In practice, both workflows converge through repeated board-to-enclosure fit checks rather than a one-way handoff. No project changes were made this session; execution stopped because your ACUs ran out.
