Box Build Assembly Terms

Terms Used in Box Build RFQs and Build Packages

These definitions describe how terms are used in a complete-unit integration context. Project drawings, specifications, contracts and responsibility assignments remain the controlling requirements.

Box Build Assembly

Integration of mechanical, electrical and electronic elements into a finished unit or defined subsystem, followed by the agreed inspection, test, identification, documentation and packaging activities.

System Integration

Coordinating parts and interfaces so the complete unit is assembled, configured and verified as one system rather than as unrelated components.

Turnkey

A project scope in which one accountable workflow coordinates the agreed sourcing, integration, testing, documentation and delivery activities. The exact boundary is defined in the quotation and responsibility matrix.

PCBA Integration

Installing an approved printed circuit board assembly into the Box Build and coordinating its mounting, connector access, grounding, thermal interfaces, internal connections, configuration and finished-unit verification.

Cable Harness Integration

Routing, connecting, retaining and inspecting approved internal cables or harnesses within the complete Box Build, including labels, strain relief, polarity, shielding or grounding requirements where specified.

Enclosure Integration

Preparing and using the product enclosure as the mechanical platform for the complete assembly, including approved panels, hardware, seals, mounting features, grounding points, connector openings and internal interfaces.

Electromechanical Assembly

Combining mechanical parts with electrical and electronic components such as switches, terminals, fans, power devices, sensors, displays and internal interconnects.

NPI

New Product Introduction: the controlled process of reviewing product inputs, resolving build-readiness gaps and establishing the material, assembly, test and record package for a new or materially changed Box Build.

First Article

The first production-intent unit or defined sample reviewed against released requirements before the rest of the planned build proceeds. The required checks and approval authority are project-specific.

Pilot Build

A limited build used to verify the product definition, assembly sequence, fit, routing, configuration, test method, records and packaging before repeat production.

Functional Test

Finished-unit verification performed against an approved procedure with defined setup conditions, expected behavior, limits, pass or fail logic and result records.

Serialization

Assigning and applying a controlled unique identifier to a unit so its physical identity can be connected to build, configuration, test and delivery records.

Traceability

The recorded relationship between a unit or batch and the applicable materials, revisions, assembly status, inspection, test, deviations, rework, serialization and shipment information required by the project.

ECO / ECR

Engineering Change Order / Engineering Change Request: controlled records used to propose, approve and release changes, including affected files, effective points and disposition of existing material or units.

Kitting

Gathering and verifying the parts, subassemblies, labels and supporting materials required for a released build or configuration before assembly.

COTS

Commercial Off-the-Shelf: a standard catalog item used within the Box Build, such as a power supply, fan, connector, switch or fastener, subject to the approved BOM and source requirements.

BOM

Bill of Materials: the controlled list of parts, quantities, approved identities, revisions and sourcing information required to build one unit or a defined product variant.

DFM

Design for Manufacturability: reviewing the complete assembly and its interfaces to identify avoidable fit, access, routing, assembly, inspection or test risks before production release.

Responsibility Matrix

A project document that identifies which party supplies, approves, integrates, tests, documents and releases each input or activity, including items outside the quoted scope.

Handover Package

The agreed set of records delivered with a build, which can include serial lists, configuration status, inspection or test results, deviation references, accessory checks, packing information and other specified evidence.
