WHAT WE DO
Our electronic box build expertise is built upon a combination of the discipline of PCB assembly and the complexity of custom wire harness and cable assembly. Together, these capabilities add up to skillfully manufactured box build assemblies that perform reliably, many in harsh environments.
In addition to manufacturing wire and cable harnesses and PCB assemblies, we are sourcing experts for components like switches, sensors, relays, DIN rails, and power supplies from trusted partners. We also source enclosures, including NEMA-rated, powder-coated, weather-sealed stainless steel, cast aluminum, and plastic in various sizes. Our refined quality control and deep industry knowledge in PCB box build assembly services ensure reliable sourcing to prevent costly problems such as part shortages or incompatibility issues down the road, making us a smart choice as your box build assembly partner.
OUR PROCESS
Box build assembly incorporates the processes for manufacturing wire harnesses and cable assemblies, as well as our process for assembling printed circuit boards in an electronic box build. Our manufacturing process incorporates inspection and testing at multiple points.
Problem Solving
Review the Bill of Materials (BOM) and assembly documents for manufacturability and discuss any ideas we have for efficiency or cost savings with the customer.
Supply Chain & Manufacturing
Source the enclosure and all of the components, then manufacture and test the PCBs and cable or wire harnesses that will be included in the box build.
Integration
Customize, assemble and test the integrated system, making sure that specifications are met and connections are robust.
Firmware
Verify that the correct firmware version is selected based on the product’s BOM, then install firmware and configure the system.
Final Testing, Completion, & Delivery
Additional testing and quality control, followed by any special considerations for packaging, labeling and shipping.
WHAT WE DO
From extremely complex small batches to high-volume standard production runs, we you can count on us to deliver jobs PCBAs, wire harness assemblies and box builds on time and on budget. Rigorous, reliable and responsive, ETI we exceeds expectations through continuous improvement, personalized service and ISO 9001:2015 quality management.

Combining electronics and/or electro-mechanical components, a box build assembly is an enclosure that contains devices that allow for the control of a piece of equipment or machinery.
We have no strict minimum order quantity, making us ideal for prototypes, complex small batches, and scaling up to high-volume production runs. Our vertically integrated process handles everything from single-unit validations to full-scale manufacturing, with refined quality control and deep industry knowledge ensuring smooth transitions and preventing costly scaling issues or overproduction risks down the road for each client.
Lead times depend on project complexity, volume and availability of customer specified parts, but our turnkey process—combined with proactive supply chain management—supports on-time delivery, often faster than multi-vendor approaches. By catching manufacturability issues early through Design for Manufacturability reviews and multi-point inspections, our refined quality control and deep industry knowledge help prevent delays from rework, integration problems, or component shortages. Provide your project details for a customized timeline estimate.
We maintain ISO 9001:2015 certification for quality management, with certified IPC and UL 508A trainers on staff, adhering to industry best practices and strict specifications. Our process includes inspection and testing at multiple points—during PCB and harness manufacturing, system integration, firmware configuration, and final testing—to guarantee robust connections and full specification compliance. This refined quality control, backed by deep industry knowledge, proactively prevents costly problems like system failures, environmental vulnerabilities, or compliance issues in demanding applications.
Costs are influenced by factors such as enclosure type and size (e.g., NEMA-rated, custom materials, finishes (such as special painting requirements or powder coating), component complexity, volume (higher quantities offer economies of scale), integration requirements, and additional services like firmware or specialized testing. Our expertise in problem-solving during the initial review allows us to suggest efficiencies and cost savings upfront, while refined quality control prevents expensive downstream issues like rework or field failures. We provide transparent quotes with no hidden fees—submit your BOM and specs for an accurate estimate.
Yes—our vertically integrated approach eliminates the complexity of multiple suppliers by sourcing all components (switches, sensors, relays, power supplies, etc.), sub-assemblies, and enclosures (from plastic to large weather-sealed stainless steel) from our trusted network. We manage the entire supply chain in one location with a single point of contact, using deep industry knowledge and refined quality controls to anticipate shortages, ensure compatibility, and prevent disruptions that could lead to costly delays or project setbacks for clients.
We are ISO 9001:2015 certified and employ certified IPC and UL 508A trainers to maintain high-quality standards across all projects. Our comprehensive multi-stage testing and continuous improvement processes guarantee assemblies meet your exact specifications, with rework covered for any workmanship-related issues. Trusted in critical sectors like medical, aerospace, and industrial controls, our refined quality control and deep industry knowledge prevent regulatory, performance, or durability problems—delivering reliable box build solutions every time.
