Engineering Support Built for Complex Industrial Programs
Industrial OEMs need more than a build-to-print supplier. They need a manufacturing partner that can help solve design, sourcing, test, and production challenges before they slow a program down.
Our team includes electrical, mechanical, software, manufacturing, and test engineers who work closely with your staff from concept through deployment. With engineering embedded alongside manufacturing and quality teams, we help you move from design intent to production-ready hardware with fewer handoff issues and faster decision-making.
We support:
- Design for Manufacturability (DFM) and Design for Testability (DFT) reviews
- Tooling and fixture design
- Prototype design and production
- Custom test planning and development
- Firmware flashing and logic programming
- Legacy design updates and reverse engineering from gerbers, PDFs, or samples
- Project management across the product lifecycle
This integrated approach helps you reduce redesigns, improve manufacturability, and shorten time to market.
We Solve Complex Challenges
Our facility handles everything from miniaturization and complex multi-layer boards to rigid-flex designs and variable board sizes. We provide automated conformal coating, advanced potting capabilities, and complete high-level assembly (HLA) to deliver finished products ready for deployment.
Quality Systems That Support Industrial Confidence
When your assemblies are part of critical machinery or infrastructure, quality has to be built into every step.
Our operations are supported by robust and flexible quality systems, including:
- ISO 9001:2015 certification
- AS9100D certification
- In-house IPC-certified instruction
- Documented, traceable manufacturing processes
- Inspection and validation throughout production
These controls help ensure consistency, accountability, and technical precision from prototype through full production.
Miniaturization and SWaP-C Optimization for Industrial Controls
Industrial electronics often must fit into smaller enclosures without giving up power, reliability, or thermal stability. We help engineering teams meet aggressive Size, Weight, Power, and Cost targets with designs optimized for real-world manufacturing.
Our capabilities include:
- Complex multi-layer PCBAs
- High-density board layouts
- Rigid-flex and flexible form factors
- Fine-pitch assembly and miniature component placement down to 0201 metric
- BGA and µBGA assembly with lead pitch down to 0.4 mm
- Large-format boards up to 18″ x 20″
- Support for boards with more than 20 layers
These capabilities allow you to reduce wiring harnesses, eliminate bulky connectors, and fit more function into constrained industrial housings.
Our engineering team also addresses thermal dissipation and power distribution early, helping your hardware maintain stable performance in compact environments.
Vertically Integrated Manufacturing Reduces Risk
Complex industrial products often stall when design, sourcing, assembly, and testing are spread across too many vendors. Our pull-thru vertical manufacturing model gives you one partner across the build process, from bare board sourcing through final higher-level assembly.
We support:
- Quick-turn prototypes
- Low- to medium-volume, high-mix production
- Surface mount and through-hole assembly
- Automated through-hole insertion
- Mechanical assembly and box build
- Higher-level assembly (HLA)
- Finished goods logistics
- Depot repair services
By consolidating suppliers and managing production in-house, we reduce coordination delays, improve communication between engineering and production, and give you better control over cost, quality, and schedule.
Our supply chain capabilities further reduce exposure through:
- Global sourcing strategies
- Long-term supplier relationships
- BOM risk analysis
- Lifecycle and sourcing-status visibility
- Supplier part validation
- Component traceability
- Counterfeit prevention controls
- Inventory management and Kanban programs
- Cost reduction initiatives
The result is a more resilient supply chain and more predictable on-time delivery.
Ruggedization for Harsh Industrial Environments
Industrial PCBAs must survive vibration, moisture, contamination, and temperature stress in the field. We apply advanced ruggedization methods to help protect performance in demanding operating conditions.
Our ruggedization capabilities include:
- Controlled humidity environments during assembly
- Automated conformal coating
- Precision potting for targeted protection
- Support for both RoHS and leaded processes
These processes help shield sensitive electronics from moisture ingress, condensation, chemicals, shock, and continuous vibration. For assemblies used in heavy-duty equipment, this added protection can reduce field failures and extend product life.
Advanced Assembly and Test Capabilities
Building the board is only part of the job. Reliable industrial electronics also require strong validation, repeatable test coverage, and fast feedback during production.
We provide comprehensive test development and validation services, including:
- In-circuit test (ICT)
- Functional test
- Flying probe test
- Automated optical inspection (AOI)
- X-ray inspection
- Custom-designed and manufactured test systems
- Custom PCBA test fixtures built in-house
- Checksum verification for embedded software
- Embedded software support tied to test platforms
Our test engineering team develops fixtures and protocols tailored to your product architecture and production goals. For prototype runs, flying probe testing supports quick-turn validation without fixture costs. For production, our in-house custom ATE and fixture development support high coverage, fast test times, and repeatable results.
This approach helps improve fault detection, reduce latent defects, and strengthen long-term field reliability.
The Path to Scalable PCBA Integration
DFM and DFT Assessment
We engage early to review your design, bill of materials, and test requirements. This helps identify manufacturing risks, sourcing concerns, and performance issues before they affect schedule or cost.
Prototyping and Custom Test Development
We build rapid prototypes and develop custom fixtures, software, and test protocols to validate performance against your operating requirements.
High-Mix Production and Higher-Level Assembly
We scale into low- and medium-volume production using flexible manufacturing lines configured for high-mix programs, then complete higher-level assembly for deployment-ready products.
Ongoing Supply Chain and Lifecycle Support
We continue to support your program through sourcing visibility, inventory strategies, traceability, and lifecycle management to help protect long-term production continuity.

Frequently Asked Questions
Can you support highly complex, low-volume production runs?
Yes. We specialize in low-volume, high-mix manufacturing for complex industrial applications. Our flexible production model is designed for customized builds that do not fit standard high-volume manufacturing.
What engineering support do you provide during design?
We provide direct support from electrical, mechanical, software, manufacturing, and test engineers. Our team helps with DFM and DFT reviews, component and layout decisions, fixture development, firmware integration, and production-readiness planning.
What types of PCB assemblies can you build?
We support complex multi-layer boards, rigid-flex designs, flexible circuits, large-format boards, fine-pitch assemblies, and BGA/µBGA packages. We also support through-hole, box build, and higher-level assembly requirements.
How do you protect PCBAs used in harsh environments?
We use controlled humidity during assembly, automated conformal coating, and precision potting to protect electronics from moisture, chemicals, vibration, and shock. These processes are selected based on the demands of your operating environment.
How do you handle testing and validation?
We develop custom test plans, fixtures, and software based on your product architecture. Our capabilities include ICT, functional test, flying probe, AOI, X-ray, and in-house custom test systems for both prototype and production programs.
How does your vertical manufacturing model reduce supply chain risk?
By managing sourcing, assembly, testing, and higher-level integration under one roof, we reduce vendor handoffs, improve traceability, and shorten response times. Combined with BOM risk analysis, supplier validation, and counterfeit prevention, this helps lower supply chain disruption.
