Turn the application into a build specification
Consumer products and wearables bring mechanical packaging, assembly cost and user interaction into the PCB design. The highest density is not always the lowest-cost solution once assembly, test and rework are included.
Mechanical integration
Model connectors, switches, displays, batteries and enclosure clearances early. State component-height limits and review flex connections in their installed configuration.
Production economics
Compare panel utilization, component standardization, setup effort and automated test coverage. A modest board-size change can improve handling without changing the core circuit.
Pilot production
Use a pilot build to validate assembly fixtures, programming, cosmetics and test limits. Record the final firmware and hardware revision together before expanding the build.
What to include in your project brief
- The actual operating environment and expected product lifecycle.
- Fabrication, BOM and assembly data under one revision.
- Required inspection, testing, traceability and shipment records.
- Any supplier qualifications or handling restrictions that must be verified before release.
