PCB-First vs Enclosure-First Design

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 packaging together: requirements, component selection, schematic, PCB layout, enclosure, and manufacturing checks.
  • PCB-first: Start with the circuit, lay out the board, then design an enclosure around its outline, connectors, and mounting holes. This works well when electronics drive the design and the case dimensions are flexible. It gives the PCB more freedom, but can lead to a larger or less polished enclosure.
  • Enclosure-first: Start with the product’s size, shape, controls, and connector locations, then fit the PCB inside those constraints. This works well for handheld products or devices that must fit an existing space. It protects the intended look and feel, but can make placement, routing, and assembly harder.
In practice, I’d iterate between both—checking fit, connector access, heat, and assembly before committing either side. No project changes were made; execution stopped because your ACUs ran out.
