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 working through the electronics, PCB, firmware, enclosure, and manufacturing needs together—checking that they fit and function as one device.
  • PCB-first: Start with the circuit, place connectors and components, then design the enclosure around the board. This suits electronics-led projects where the case can adapt; the trade-off is that board placement may dictate the product’s size and appearance.
  • Enclosure-first: Start with the product’s shape, mounting, controls, and connector openings, then design the PCB to fit. This suits products with strict size or usability requirements; the trade-off is tighter constraints on component placement, routing, and cooling.
Both workflows are iterative: you check mechanical fit, electrical behavior, and manufacturability before ordering prototypes. Your ESP32 retro-PC project was not changed this session; this was only an overview. Execution stopped because your ACUs ran out.
