Box Build & System Integration
Complete electronic system assembly and integration for customers requiring finished, production-ready assemblies.
Sigma supports programs where boards, wiring, enclosures, lighting, and mechanical components must function together as one system — reducing supplier complexity and coordinating manufacturing execution.

Overview
Box build and system integration involve the assembly of complete electronic systems, including PCBAs, cables, connectors, housings, lighting elements, and other subcomponents. These systems are built to customer requirements and prepared for installation within the final product or vehicle.
Sigma supports programs where electronics must be assembled into a finished unit rather than delivered as individual boards or loose components. This enables customers to simplify sourcing, reduce internal assembly burden, and improve launch coordination.
