Define the delivery boundary
How does box build differ from PCB assembly?
PCBA delivers a populated circuit board. A box build adds the electrical and mechanical integration needed for an agreed subassembly or finished unit. The purchase scope should state exactly what is sourced, installed, programmed, tested and packed.
| Scope | Typical output | Additional information required |
|---|---|---|
| PCB assembly | A populated board with agreed board-level inspection and testing. | PCB files, electronic BOM, placement data, drawings and acceptance requirements. |
| Electromechanical subassembly | One or more boards integrated with defined wiring and mechanical parts. | Mounting details, wiring information, interface requirements and subassembly test scope. |
| Complete box build | A defined enclosure assembly with the agreed electronics, interconnects, software and accessories. | Mechanical BOM, enclosure drawings, harness definitions, firmware, final tests, labeling and packing instructions. |
Start with our one-stop PCB assembly service when the main requirement is the board. Use a box-build inquiry when enclosure fit, wiring, programming or complete-unit acceptance also belongs in the project.
A project-specific scope
What can be included in a box build?
The scope can extend from a small PCB-and-harness module to a multi-board enclosure. Define the required operations at quotation; enclosure procurement, fabrication routes, specialist processes and test arrangements are confirmed for the actual design.
PCB fabrication and assembly
Review bare-board construction, the electronic BOM, SMT assembly, through-hole work and board-level verification before integration.
Enclosures and mounting
Define the housing, brackets, standoffs, fasteners and installation sequence. Provide released drawings and specify whether the selected enclosure is standard or custom.
Cables and interconnects
Specify cable lengths, connector families, mating parts, pinouts, labels and routing. Include any shield termination, strain relief and harness test requirements.
Power and thermal parts
Identify power modules, fans, heat sinks, thermal interfaces and grounding requirements. Assembly instructions need the relevant orientation, fastening and electrical details.
Programming and configuration
Supply the approved firmware, programming method, version identifiers and model-specific settings. Define how the correct configuration will be verified.
Identification and pack-out
Agree unit labels, serial-number rules, accessories, documentation, protective packaging and shipment quantities. Match the packaging to the finished assembly.
Special requirements such as sealing, coating, calibration or safety testing need a defined specification and separate confirmation. An enclosure rating or a component approval does not automatically establish compliance of the completed product.
Resolve interfaces before production
The electronic BOM is only part of the build package
A useful box-build package links the electronic BOM, mechanical BOM, drawings, wiring and software to the same released product configuration. Missing interfaces can delay assembly even when the PCBA itself is complete.
| Interface | Information to release | Decision before the build |
|---|---|---|
| PCB to enclosure | Board outline, mounting holes, component heights, connector locations and enclosure drawing or 3D data. | Confirm fit, standoff height, fastener access and the installation sequence. |
| Harness to electronics | Mating connectors, pinouts, wire specification, cable length, routing and identification. | Confirm connectivity, keying, movement clearance and strain relief. |
| Power and protective connections | Supply ratings, polarity, grounding or bonding details and applicable product requirements. | Define installation and verification instead of inferring them from a wiring color. |
| Thermal and moving parts | Heat-sink and fan orientation, thermal interface details and required mechanical clearances. | Check interference, routing and service access before closing the housing. |
| Software to hardware variant | Firmware release, programming instructions, configuration settings and identifiers. | Match the correct image and settings to the intended board and unit model. |
| Unit to final test | Test connections, firmware, loads, fixtures, pass/fail limits and required records. | Confirm that the assembled unit can be tested before it is packed. |
Connector-specific requirements matter. TE Connectivity’s connector assembly guidance explains the importance of contact seating, wire routing and strain relief; the applicable connector instructions should guide the actual harness assembly.
High mix · Low and medium volumes
Control multiple models without losing the configuration details
OrinewPCB focuses on one-stop PCB assembly for small and medium batches with varied designs. In a box build, that means tracking more than board variants: housings, cables, firmware, labels and acceptance limits may change too.
One released identity per model
List the product code, quantity, revision, PCBA variant, enclosure, harness and firmware. Make the differences explicit even when the units look similar.
Shared parts, approved differences
Identify common materials and model-specific items. DNP positions, alternate parts and mechanical changes need clear approval rules before sourcing or assembly.
A repeat-order baseline
Keep the approved files, work instructions and acceptance requirements together. For a change, provide the new revision and an engineering change list.
For a prototype or pilot build, agree which findings must be closed before the next batch. A successful board-level test does not by itself approve a changed enclosure or a different firmware configuration.
From quotation to repeatable assembly
A practical box-build production process
The build should progress through clear scope, material, integration and acceptance decisions. Agree the deliverables and unresolved questions before committing the full production quantity.
-
Agree the supply and acceptance scope
Review the electronic and mechanical requirements, quantities, sourcing responsibilities, test scope and target date. Identify missing drawings or unapproved component choices.
-
Prepare materials and the PCBA
Coordinate PCB fabrication, 100% new original component sourcing, assembly and the agreed board-level checks. Confirm the enclosure, harness and hardware requirements alongside the electronics.
-
Verify the initial integration
Check fit, connectors, routing, fastening access and the programming method on the initial units. Agree what evidence is needed before continuing the batch.
-
Close findings and release repeat work
Resolve drawing conflicts or fit issues, record approved changes and update the controlled configuration. Use the agreed assembly sequence for repeat units.
-
Complete unit acceptance and pack-out
Carry out the specified final inspections and tests, verify the model and firmware identity, and check labels, accessories and protective packing before shipment.
Original components · Defined verification
A nine-step quality workflow, extended to the agreed unit scope
Quality is a priority at OrinewPCB. We use 100% brand-new original components and a nine-step inspection and testing workflow. For a box build, the quotation must also identify the applicable mechanical, wiring, software and complete-unit acceptance requirements.
Original component supply
Deep cooperation with manufacturers and distributors supports genuine electronic components, competitive material prices and practical availability. Define approved part numbers and substitution rules.
Checks tied to the configuration
Confirm the correct board, enclosure, harness, firmware and label for each model. Identify the inspection points that become inaccessible after the enclosure is closed.
Evidence agreed before production
Specify the test records, programming information, serial-number mapping or inspection evidence your project needs. Include any customer-specific requirements in the RFQ.
| Verification level | What it addresses | Requirements to agree |
|---|---|---|
| PCBA inspection and test | Assembly features and defined electrical or functional checks on the populated board. | Coverage, test access, firmware, limits and records. |
| Mechanical and wiring checks | Mounting, connector seating, routing, fasteners and the specified wiring configuration. | Drawings, workmanship requirements, fastening instructions and inspection access. |
| Programming and identification | Correct software release, settings, product labels and unit identity. | Approved files, version verification, identifier rules and any required logs. |
| Complete-unit functional test | Operation of the integrated product with the defined interfaces, inputs and loads. | Fixtures, procedures, operating conditions and measurable pass/fail criteria. |
| Special product tests, if required | Specified burn-in, thermal, protective connection, insulation or other product-specific evaluations. | Feasibility, conditions, duration, applicable standards, sample plan and evidence. |
These are planning categories, not a replacement list for the nine-step workflow. Burn-in, safety tests and certification activities are not automatic inclusions in every order. A component or PCBA test does not establish the compliance or complete function of the finished product.
For a combined board and enclosure order, share the build files and acceptance requirements so the applicable inspection and testing scope can be included in the quotation.
Pre-build integration review
Questions worth resolving before parts are committed
The most useful review checks how the actual items assemble, connect and get tested. A dimensionally correct PCB can still be difficult to install, wire or inspect inside its enclosure.
Mechanical and cable access
- Do tall components, connectors and cables fit with the cover installed?
- Can fasteners be reached in the intended assembly sequence?
- Are standoff heights, mounting details and fastening requirements defined?
- Can cables route without pinching, excessive bends or rubbing on edges?
- Are connectors keyed, fully seatable and adequately supported?
Power, software and acceptance
- Are supply polarity, protective connections and interface pinouts unambiguous?
- Are thermal parts and airflow requirements defined by the product design?
- Does every model have the correct firmware and configuration release?
- Can the final unit connect to the required test fixtures?
- Which checks must happen before closure, and which after final assembly?
Competitive total project cost
What determines the box-build price?
Pricing depends on the complete electronic and mechanical scope. Our manufacturer and distributor relationships help support favorable component prices and supply schedules; the quote also needs to account for integration and verification work.
- PCB fabrication and the approved electronic BOM.
- Enclosure, harness, hardware and other mechanical materials.
- Assembly effort, preparation, setup and product variants.
- Programming, fixtures and agreed unit-level testing.
- Labels, documentation, accessories, packaging and delivery arrangements.
Compare quotations using the same BOMs, drawings, quantities and acceptance criteria. Confirm any one-time tooling or fixture costs separately from recurring unit cost.
The earliest practical delivery
How is delivery scheduled?
The schedule follows the longest unresolved dependency across electronics, mechanical parts, integration and test preparation. A stocked PCB component alone does not make the complete unit ready to ship.
- Provide the target date and quantity for each model.
- Release the enclosure and harness information with the PCB files.
- Identify long-lead parts and approved substitution rules.
- Supply firmware and test requirements before production setup.
- Close pilot-build findings before releasing repeat quantities.
We work toward fast practical delivery while retaining the agreed quality scope. Review quick-turn project requirements with the complete build package.

Box build assembly FAQ
Questions before a box-build order
Does box build mean manufacturing the enclosure?
It means integrating the agreed electronics and mechanical parts into an enclosure or subassembly. Enclosure sourcing, custom fabrication, finishing and ownership need to be defined in the quotation; they should not be assumed from the term alone.
Can you review small batches with several models?
Yes. High-mix, low- and medium-volume one-stop PCBA is a core focus. Provide quantities and controlled configurations for each model so sourcing, setup, assembly and test requirements can be reviewed.
Can I start with only the PCB files and BOM?
Yes, for an initial discussion. A complete box-build quotation also needs the relevant mechanical, wiring and acceptance information. Identify missing documents so open assumptions are visible before the scope is finalized.
Are all nine quality steps identical for every product?
OrinewPCB uses a nine-step quality workflow, while the applicable methods and acceptance requirements depend on the design. Confirm the inspection, test coverage and required evidence for the specific board and finished unit.
Are burn-in and electrical safety tests always included?
No. Requirements, test conditions, duration, fixtures, standards and feasibility must be agreed for the product. Basic assembly inspection is not a substitute for the required safety or compliance assessment.
How do you support original components and competitive pricing?
We use 100% brand-new original components and have deep cooperation with manufacturers and distributors. These relationships support material pricing and availability; approved manufacturer part numbers and substitution rules remain part of the build requirements.
Can you program firmware and assign product identifiers?
Include the required programming method, approved software release, configuration settings and identifier rules in the inquiry. The programming, verification and record requirements are confirmed within the project scope.
How should changes after a pilot build be handled?
Release an updated product revision and a clear change list. Check the effects on the PCBA, mechanical parts, harnesses, firmware, labels and test limits before continuing production.
