Our box build and integration specifications.
What Box Build and Systems Integration Covers
The build boundary follows the product documentation and can include electrical, electronic, and mechanical integration.
Enclosure Preparation
Prepare the enclosure for assembly, including specified cutouts, holes, inserts, mounting features, and other machining shown on the controlled drawing.
Harness, Panel, and Backplane Wiring
Install and route harnesses and cables, terminate connections, and complete panel or backplane wiring according to the wiring diagram and identification scheme.
PCBA and Component Integration
Mount PCBAs, power supplies, controls, displays, fans, switches, and other specified components while maintaining the required orientation and access.
Final Mechanical Assembly
Fit brackets, covers, fasteners, seals, and remaining hardware; apply labels; then complete the final enclosure and product-level assembly.
Inspection and Test
Check workmanship and configuration during the build, verify electrical connections, and perform the functional checks defined for the assembled unit.
Packaging and Turnkey Delivery
Pack the approved configuration with the specified accessories and documentation, whether the delivery is a sub-assembly or a complete turnkey product.
Levels of Box Build Assembly
Box build is a spectrum, not a universal numbered standard. A lower-level scope may deliver a wired panel, mounted electronics module, or enclosure sub-assembly for installation elsewhere. A broader scope may combine sourced parts, complete internal integration, product-level test, labeling, accessories, and final packout as a turnkey build.
The practical boundary is agreed during quotation: customer-supplied versus sourced material, assembly operations, configuration variants, test responsibility, acceptance evidence, and the condition in which each unit must be delivered. Drawings, the BOM, work instructions, and the test plan should describe that boundary clearly.
Box Build or a Bare Harness?
Choose a bare wire harness when your team will install it, controls the enclosure build, and only needs the cable-level deliverable and test records. Choose box build when the purchasing objective is an integrated sub-system or finished unit rather than a set of separately managed parts.
Consolidating the work can provide one accountable supplier for fit, routing, connection, and final configuration; reduce handoffs between harness, electronics, enclosure, and assembly vendors; and move defined integration tests upstream before the unit reaches your line.
For wiring-led cabinets, review control panel wiring assembly. For equipment programs where logistics and installation interfaces drive the scope, see our industrial applications.
Testing and Quality Through the Build
Checks are matched to the assembly stage so faults can be found before they are hidden by later integration.
In-Process Checks
Confirm part identity, orientation, routing, connections, hardware, and configuration while these features remain accessible.
Continuity and Functional Test
Use the approved procedure to verify intended electrical paths and exercise specified functions of the integrated assembly.
Final Assembly Inspection
Review workmanship, labeling, connector engagement, enclosure condition, accessories, and the released build configuration before packout.
Factory Acceptance Test
Where the program requires a FAT, run the customer-agreed system checks and record evidence against the defined acceptance criteria before release.
Test coverage, fixtures, records, and pass/fail criteria are agreed from product risk and customer requirements. See the broader testing capabilities for cable- and assembly-level verification options.

Box Build Assembly and System Integration Services
As a specialized box build assembly provider, OurPCB delivers complete system integration for enclosures, control panels, and electronic assemblies with wire harness and cable assembly integration. Box build simplifies your supply chain by consolidating assembly with a single supplier.
Complete enclosure assembly includes wire harness installation, PCB mounting, component integration, and hardware installation. Control panel builds with proper wire routing support industrial automation and robotics applications. Medical device sub-assemblies meet regulatory requirements.
Component sourcing for enclosures, hardware, and electronics reduces your procurement burden. Our testing capabilities verify completed assemblies with functional and safety testing. Labeling and packaging delivers ready-to-ship products.
Engineering support develops assembly procedures and BOMs from customer drawings. Prototype builds validate assembly processes before production. Quality systems per ISO 9001 ensure consistent assembly quality.
Turnkey solutions from component sourcing through final packaging streamline your operations. Automotive and aerospace programs benefit from complete assembly documentation and traceability. If your RFQ is centered more narrowly on terminal mapping, conductor ID, and cabinet-level release control, our control panel wiring assembly service is the better fit. Contact us to discuss box build and system integration for your products.
Frequently Asked Questions
Box build refers to assembling complete systems in enclosures, including installing wire harnesses, PCBs, components, and hardware. We deliver tested, ready-to-install or ready-to-ship units.
Yes, we can source components, hardware, and enclosures for your box build. This simplifies your supply chain by consolidating sourcing and assembly with a single supplier.
Testing depends on your requirements. We can perform functional testing, safety testing, burn-in, and other tests. Test procedures and pass/fail criteria are established during program setup.
Yes, we work from customer assembly drawings, BOMs, and specifications. We can also develop assembly documentation if needed. Engineering support is available for design reviews and optimization.
Harness-only manufacturing stops at the cable or wire assembly, while box build adds enclosure installation, mechanical assembly, electronics integration, labeling, and final functional verification for the full unit.
The agreed scope can include enclosure preparation and machining, harness and cable installation, PCBA and component integration, panel or backplane wiring, labeling, final mechanical assembly, testing, and packaging. The exact deliverables, supplied materials, test procedures, and acceptance criteria are defined from the drawings, BOM, and RFQ rather than assumed from the term box build alone.
Contract assembly is a broad manufacturing category that can describe anything from a component sub-assembly to a finished product. Box build is a more specific system-integration scope focused on assembling electrical, electronic, and mechanical items in or around an enclosure. A box build can therefore be one type of contract assembly, with the boundary set by the BOM, drawings, test plan, and delivery requirements.
