The unit—not a single part—is the scope
Our work is judged against the agreed condition of the complete assembly: what is installed, connected, configured, checked, identified, documented, packed and delivered.
One Accountable Integration Workflow
About Turnkey Box Build
We coordinate enclosure, PCBA, cable harness and electromechanical inputs into tested, documented Box Build assemblies for OEM products. Our role is to keep the complete-unit scope, interfaces, verification and handover aligned.
- Complete Box Build integration
- Project-defined testing and records
- One coordinated delivery scope

Purpose
Why Turnkey Box Build Exists
OEM teams often have capable suppliers for individual parts but still carry the coordination burden between the enclosure, electronics, internal wiring, software, test procedure and final delivery package.
Turnkey Box Build exists to close those interface gaps. We organize the approved inputs around one finished-product definition and keep material status, assembly decisions, verification requirements and handover outputs visible throughout the build.
Accountability
What We Take Responsibility For
We take responsibility for the Box Build activities included in the approved project scope. That can cover scope review, input coordination, assembly and integration, project-defined verification, configuration, records, labeling, packaging and final delivery.
The responsibility matrix also identifies customer-supplied materials, customer-owned tools or software, approval gates, exclusions and decisions that require written authorization. We do not blur those boundaries or present unagreed work as included.
Define
Align the product files, responsibilities, revisions and acceptance criteria.
Integrate
Bring mechanical, electronic and wiring inputs into the complete assembly.
Verify
Run the agreed inspection, functional and configuration checks.
Deliver
Complete the specified records, accessories, labels and packaging.
Coordinated resources
How the Manufacturing Network Supports Delivery
Our delivery model combines the enclosure and mechanical capabilities shown below with established PCBA and cable harness manufacturing resources. We coordinate these inputs only in the context of a complete Box Build, keeping their approved revisions and system interfaces aligned with the final assembly.
This network model does not mean every upstream process is performed in one owned facility. It means we remain accountable for coordinating the scope we accept and for making supply and approval responsibilities explicit.

Controlled sequence
Our Box Build Workflow
We start with RFQ and scope review, then plan NPI or pilot activity, prepare approved material and instructions, integrate the unit, perform the agreed verification, and assemble the required handover package.
Changes, deviations and missing inputs can place work on hold until the authorized customer or project decision is recorded. This keeps the released configuration and affected units understandable.

Evidence for the agreed scope
Quality and Documentation Approach
Quality controls are defined around the product and its risks. Incoming status, first-unit findings, in-process checks, serial identity, functional results, deviations and configuration data can be recorded to the depth agreed for the project.
Box Build work can be produced under ISO 9001 · IATF 16949 · ISO 13485 · ISO 27001 · ISO 45001 · ISO 14001 certified manufacturing systems. These standards are presented as plain text only; we do not display certification logos or claim that Turnkey Box Build is the certificate holder.
Review quality control and traceabilityDocumentation follows the contract
- Approved BOM, drawing, software and test revisions
- Inspection and functional-test records as specified

Technical Content and Leadership
Hommer Zhao, Founder & General Manager, leads Turnkey Box Build and is the named author behind our technical guidance. The content is intended to help OEM teams define interfaces, RFQ inputs, test responsibilities and handover evidence before a build begins.
We keep authorship visible so readers can distinguish accountable technical guidance from anonymous marketing claims.

Begin with current information
Start With the Scope You Have
You do not need a perfect RFQ package to begin a scope review. Send the current BOM, drawings, enclosure CAD, harness information, test notes, build quantity and known open decisions. We will identify what is confirmed, what remains an assumption and what must be resolved before quotation or release.
