Box Build Assembly is the process of assembling complete electronic or electromechanical systems beyond standard PCB assembly. This includes installing PCBs into enclosures, routing cables and wire harnesses, integrating sub-assemblies, configuring power supplies, and managing product labeling and packaging.
Unlike standard PCB assembly, Box Build requires a combination of mechanical, electrical, and functional expertise to deliver finished, end-user-ready products such as compact medical devices, industrial control panels, or complex communication systems. The complexity of Box Build Assembly varies widely. It can involve anything from simple enclosures to intricate systems with multiple sub-assemblies, thermal management solutions, embedded software, and strict regulatory compliance.
From simple mechanical builds to complex multi-level enclosures, our box build capabilities are tailored to meet your technical, compliance, and delivery needs, ensuring efficient, end-to-end integration.
