Transforming Electronic Assemblies into Complete Products
SDI box build programs turn populated PCBs, harnesses, and sub-assemblies into finished, ship-ready products — enclosure integration, functional testing, and packaging under one coordinated program.
Our Silicon Valley team manages mechanical fit, electrical interconnect, firmware provisioning, and factory QA so your complete product ships consistently — not just the board inside the box.
Complete Product Integration
Where schematic-level electronics become a product customers can hold, use, and deploy.
Box build is the convergence point — PCB, enclosure, battery, sensors, display, and firmware must align in physical space with tolerances, thermal paths, and service access validated before the line runs.
SDI coordinates mechanical, electrical, and firmware teams during integration so assembly issues are resolved in engineering — not discovered on the factory floor.

Request Free EstimateFrequently asked questions
Common questions about box build assembly, integration, testing, packaging, and production timelines.
What is box build assembly?
Complete product integration — PCB, enclosure, harness, battery, and peripherals assembled into a finished, tested, ship-ready unit.
How is box build different from PCB assembly?
PCB assembly populates boards; box build integrates those boards into complete products with mechanical, electrical, and functional validation.
Do you handle firmware provisioning on the line?
Yes. In-line flashing, calibration, and serial/MAC assignment are coordinated with embedded engineering.
What product categories do you support?
IoT, robotics, consumer electronics, medical, industrial, and AI hardware platforms among others.
Do you provide functional testing?
Power-on, communication, sensor calibration, and user-flow tests aligned to your golden unit reference.
Can you manage packaging and labeling?
Yes. Regulatory labels, serialization, retail packaging, and fulfillment-ready ship configuration.
Do you coordinate with enclosure and mechanical teams?
Yes. Box build programs integrate mechanical DFM, torque specs, and fit validation from engineering.
How long does a box build program take?
Pilot builds typically run 3–6 weeks; production programs depend on complexity and volume targets.
Do you support low-volume pilot builds?
Yes. EVT/DVT box builds are coordinated before full production ramp.
