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.

Designing a complete product in Flux means working through the electronics, PCB, enclosure, and how they fit together—not just drawing a circuit.
  • PCB-first: Start with the circuit, then place and route the board. Design the enclosure around its outline, connectors, mounting holes, and cooling needs. This suits electronics-led projects, though the case may need to grow to accommodate the board.
  • Enclosure-first: Start with the product’s size, shape, controls, and connector locations. Fit the PCB into that space and design the electronics around those constraints. This suits products where appearance, handling, or mounting matters most, but can make board layout more demanding.
Both workflows are iterative: expect to adjust the board and enclosure together as fit, thermal, and manufacturing constraints emerge. For this retro PC, PCB-first is a natural starting point unless you have a specific case or desk footprint in mind.
No project changes were made. Execution stopped because your ACUs ran out.
