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 design together—requirements, schematic, PCB, enclosure, and manufacturing files—with checks and iteration along the way.
  • PCB-first: Start with the circuit, then size and arrange the board around electrical needs. Design the enclosure around the board, connectors, and mounting points. This feels electronics-led: useful for prototypes and products where circuit performance matters more than a fixed shape.
  • Enclosure-first: Start with the product’s size, appearance, mounting, and user-facing controls. Shape the PCB and position connectors to fit that envelope. This feels product-led: useful for handheld devices or products that must fit an existing space, but mechanical constraints can make layout harder.
Neither is strictly one-way—you iterate between board and enclosure to resolve fit, access, heat, and assembly. I haven’t changed your project this session; execution stopped because your ACUs ran out.
