Qualification & Ruggedization

At North Atlantic Industries (NAI), we take pride in our certified quality systems, which meet the standards of AS9100 Rev. D, ISO9001:2015, and Federal Aviation Regulations FAR 21 & FAR 45.15. Our commitment to these standards is the foundation of our excellent reputation in delivering top-quality products.

Our dedication to customer satisfaction has been recognized by numerous clients, who have commended us for outstanding service and partnership, meeting all safety standards, and exceeding their expectations. We are honored to have received awards such as the Performance Excellence Gold Award from Boeing and the Supplier Excellence Award from Raytheon.

Quality Assurance

At NAI, we are dedicated to upholding the highest standards of quality and excellence in everything we do. To ensure this, our in-house certified QCI trainer provides comprehensive training to all company assemblers and testers, ensuring that they are trained and certified to IPC-A-610 standards.

In addition, we utilize our own in-house Automated Test Equipment (ATE), which not only helps us reduce delivery time to our customers but also ensures that every product undergoes rigorous testing throughout the production cycle, guaranteeing uniform standards of quality.

Testing Capabilities

At NAI, our on-site testing capabilities cover every aspect of the production process, including design verification, product qualification, and environmental testing (EMI, temperature, and vibration). To ensure that our testing is as efficient and accurate as possible, we rely on advanced automation technology to achieve consistent, repetitive, and precise results.

We understand the importance of delivering products that meet the highest standards of quality, reliability, and performance. That's why NAI utilizes in cutting-edge technology and equipment and have a highly trained staff dedicated to ensuring that every product we produce meets our rigorous testing standards.

At NAI, after new products are released from our engineering department, they undergo a comprehensive series of tests performed by our design verification test team. This team conducts a rigorous battery of tests, including electrical performance verification testing to design specifications, as well as environmental and qualification testing.

We are committed to ensuring that every product we produce meets the highest standards of quality, reliability, and performance. That's why our design verification test team works tirelessly to thoroughly test every new product, leaving no stone unturned in the pursuit of excellence.

At NAI, we are proud to offer on-site temperature Environmental Stress Screening (ESS) capabilities. Our temperature ESS capabilities cover a wide range of products, from card level and small footprint NIU units to large, ruggedized embedded systems. Our design verification testing includes temperature cycling from -40° C to +85° C and electrical performance testing at the extremes. All conduction-cooled products are tested to specified temperature ranges to accommodate customer-specified production deliveries.

At NAI, we offer on-site vibration ESS capabilities to ensure that our products can withstand the most rigorous environmental conditions. Our vibration screening can be performed on all three axes, and our units can be instrumented and monitored during testing with data capture (or run passively with no power).

Our vibration test systems are computer-controlled and can be programmed to simulate a wide range of vibration scenarios tailored to meet our customers' requirements. We are committed to providing products that can perform reliably in even the harshest environments.

NAI has extensive environmental and EMI qualification capabilities, which include temperature, vibration (sine & random), shock, humidity, and conducted emissions. We are committed to providing our customers with products that are tested to the most rigorous standards, and our on-site testing capabilities allow us to ensure that every product meets our exacting quality standards.

In addition to our on-site capabilities, we also supplement our testing with local test laboratories for specialized testing. This allows us to provide our customers with even more comprehensive testing capabilities, including altitude, temperature-altitude, contaminant protection, explosive atmosphere, MIL-STD-461 EMI, and lightning testing.

NAI offers a diverse range of products, from low-volume/high-mix to high-volume production runs, tested with internally designed multi-unit gang testers and an automated test software suite. This suite is continuously updated and refined to keep up with our customers' evolving needs, allowing us to maximize throughput without sacrificing test coverage or product quality. Our advanced final production testing capabilities encompass every facet, from design verification and product qualification to environmental testing, EMI qualification, and vibration screening.

NAI Design and Environmental Standards

NAI produces rugged, high-performance products that can withstand harsh conditions like temperature changes, vibration, shock, and corrosion. Our design tools use advanced simulation software, and we meet environmental standards like MIL-STD-810 and VITA 47. We have in-house qualification capabilities for environmental and EMI ruggedization, and we use local test labs for altitude, temperature-altitude, and MIL-STD-461 EMI testing as needed.

Our testing covers temperature, vibration, shock, humidity, and conducted emissions. We also offer protection against contamination, explosive atmospheres, and lightning. Our products are highly efficient and perform well even in the harshest environments.

For design guidelines, please refer to the General Environmental Specifications tables.

All of our cPCI, VME and OpenVPX boards are designed for either air or conduction cooling. All boards also incorporate appropriate stiffening to ensure performance during shock and vibration and to assure reliable operation (lower fatigue stresses) over the service life of the product.
