For engineers and innovators driving mission-critical projects, success depends on uncompromising precision, proven reliability, and rapid execution.. VSE delivers on those critical needs with proven practices that reduce risk, safeguard quality, and accelerate timelines. The following pillars outline how we foster trust with our partners and enable them to bring complex technologies to market.
Introduction →
Why VSE is A Trusted Partner for Complex Assembly Needs
U.S.-Based, Vertically Integrated Manufacturing
With facilities in San Jose, CA, and Reno, NV, VSE provides complete box build and Printed Circuit Board Assembly (PCBA) services under one roof. Our domestic operations ensure shorter lead times, tighter supply chain control, and the security that comes with U.S.-based production. From design review to final assembly, vertical integration means fewer handoffs, reduced risk of error, and seamless scaling when demand grows.
Certified Quality You Can Trust
Every build undergoes rigorous testing and inspection backed by certifications including ISO 9001, ISO 13485, and IPC 610/WHMA-A-620. Our engineers apply DFM, DFA, and DFT best practices to identify potential issues early. In-circuit, functional, and environmental testing further ensures assemblies perform reliably in the field.
With systematic quality control and full traceability, VSE gives you confidence that your products will perform exactly as designed.
Collaboration That Lasts Beyond the Build
VSE is more than a manufacturer. We don’t just assemble products—we co-engineer success, acting as an extension of your team. From early design reviews to supply chain planning, we partner closely to anticipate challenges and deliver tailored solutions. Our approach fosters long-term relationships built on transparency, responsiveness, and shared commitment to bringing breakthrough technologies to market.
End-to-End Builds That Meet Every Expectation
A box build must do more than bring components together—it has to align with design specifications, meet safety requirements, and function as a complete, reliable system. When different suppliers handle each step, clients often face fragmented quality control and added management burdens.
VSE eliminates those risks with an end-to-end process that integrates every stage of assembly and owns the entire build process under one roof, from PCBAs and wire harnesses to cable assemblies, enclosures, and final system testing. This allows our team to apply quality assurance holistically, ensuring each unit is verified as a complete system before release.
With lean, fast-turn prototyping and high-volume production in San Jose and Reno, VSE also provides a clear path from NPI to scale. The result is higher-quality assemblies, reduced risk, and the confidence that every build is production-ready.
Inside A Complete PCBA Solution
A true box build integrates every stage of production into a single, reliable system, where each element plays a crucial role in performance, safety, and durability.
| PCBA | Wire Harness / Cable Assembly | Enclosure |
|---|---|---|
Every build begins with the precise assembly of components. Stackup design accounts for electrical, thermal, and mechanical factors, while assembly methods ensure strong bonds that minimize thermal stress over time. |
Custom cables are engineered for demanding applications and routed in 3D space for optimal performance. Careful attention to bend radii and cable thickness extends service life and ensures reliable interconnections. |
The final system comes together within a protective enclosure, where MCAD-ECAD integration minimizes shock, vibration, and exposure to debris or moisture. Cooling solutions, both active and passive, are incorporated to maintain stable performance. |
Tailored Box Build Solutions For Every Project Specification
At VSE, the same precision and quality that defines our printed circuit board assemblies carries through to every box build. These services are adaptable to a wide range of project specifications, ensuring each system is built to perform reliably in its intended application. Key specification areas include:
Size
From compact, portable devices to large-scale industrial equipment, VSE accommodates a wide range of box build sizes.
Type
Box builds are configured to meet project needs, ranging from streamlined, form-fitting enclosures to rack-mounted systems that support multiple boards.
Power
Assemblies can be engineered for high-voltage capacity ratings up to 30 kV.
Terminations
Our builds support high-density designs, with the capability to integrate thousands of board-to-board connections.
Electronics
In addition to PCBAs, wire harnesses, and cable assemblies, VSE can incorporate Original Equipment Manufacturer (OEM) electronics such as power supplies and control panels to deliver a complete device.
Integrated PCBA Manufacturing To Box Build Assembly Solutions
Many providers offer box build services, but few have the expertise to deliver complete builds with rigorous electrical testing. When manufacturing is segmented across multiple vendors, clients face added coordination, longer timelines, and a higher risk of errors.
VSE removes those obstacles by bringing every stage of production under one roof, from PCBAs and wire harnesses to cable assemblies and protective enclosures. This integrated approach reduces complexity, enhances quality control, and accelerates delivery, providing innovators with a single, trusted partner for their most critical projects.
To deliver reliable assemblies on time, we strengthen this process with the following key practices that reduce risk and improve performance:
When multiple partners are involved, design data can become fragmented, leading to miscommunication, mismatched revisions, and ultimately ending in costly rework. VSE eliminates that risk by working directly with design teams to verify and align data at the start of each project. We then maintain consistency throughout the build. This streamlined approach reduces errors, shortens timelines, and safeguards product integrity from prototype through production.
When different partners handle sub-products, mismatches in fit or function can create costly setbacks. At VSE, the PCBA, wire harness, and enclosure are all developed and tested together. This ensures smooth integration, reliable assembly, and confidence that every component functions as part of a complete system.
When sub-products are developed in sequence, delays and misalignments can lead to costly rework and integration issues. VSE avoids those risks by developing all sub-products in parallel. Our synchronized process keeps every element aligned, shortens timelines, and ensures seamless coordination throughout the entire project.
Effective troubleshooting is critical to avoiding delays and ensuring reliable performance. When integration issues arise, VSE applies its deep understanding of electromechanical interactions to quickly detect and resolve problems. This proactive approach keeps projects on track and builds confidence in the final assembly.

Commitment To Quality Standards In Every Precision Build
Every VSE product undergoes strict quality control measures that verify compliance with both customer requirements and industry standards before release. Our processes ensure that each stage of the build is tested, inspected, and validated for reliable performance.
1
Sub-Assembly
Each sub-assembly, including circuit boards and wiring harnesses, undergoes individual testing to confirm operational performance before integration.
2
Box Build
Critical details, such as labeling, wire routing, torqued screws, and continuity test points, are verified to ensure full inspectability throughout the build.
3
Testing
The completed box build is tested against custom-developed specifications and applicable industry standards to ensure it is ready for service.
