Rolling Wireless is a fabless company. Our automotive NADs are produced by our manufacturing partner Flex Ltd. in its IATF 16949-compliant facility in Suzhou, China Mainland.
Over almost two decades of lessons learned and continuous improvement, working closely with customers and expert advisors, we have turned our production floor from a factory running continuously with more than 300 operators to a fully automated production line managed by a handful of operators and supervisors.

Rolling Wireless places a strong emphasis on delivering products that meet the highest standards for reliability. We achieve this by incorporating quality and reliability checks at every level in our product design and manufacturing processes, and throughout the product life cycle.
High reliability and low defect rates are established during product design. Our standardised approach to automotive designs, building on prior lessons learned, includes:
We consider that product reliability assessment does not stop at the end of the design phase, but has to be continuously monitored throughout the mass production life of our modules. This is why we apply an Ongoing Reliability Test (ORT) in our factory by sampling, every month, each of our product families.
The ORT helps us ensure process stability and parts quality. We can capture any drift that would be related to product ageing in an automotive environment, and stop any risky lots of modules. Our ORT combines our own experience accumulated over the years with recommendations from world-class reliability experts specialising in the automotive domain.
To be as close as possible to the customer environment and real field stress conditions, our modules are first soldered on PCBAs that simulate the customer application board by size, thickness, and type of PCB materials used, before they undergo the ageing test. In this way, our ORT includes the customer reflow effect as well as possible CTE mismatch effects between the application board and the module.
Based on our experience and confirmed with experts in the domain, the 2nd reflow and CTE mismatches are very high-stress factors that trigger most of the latent hardware defects that would have become visible in the first years of the product's life.

Our quality policy is designed to guarantee the safety, reliability and quality of our products and services, and to ensure the satisfaction and trust of our customers, partners, and suppliers.
Rolling Wireless is committed to developing a clear strategy for social and environmental responsibility that includes all aspects of our operations.
Third-party certification bodies provide independent confirmation that Rolling Wireless and our manufacturing partner meet the requirements of all relevant global quality standards.
To ensure continuous improvement, we measure customer satisfaction in annual customer survey workshops and with frequent transactional satisfaction surveys.
Our automotive quality processes include Failure Analysis and 8D, Advanced Product Quality Planning (APQP), Automotive Production Part Approval Process (PPAP), and more.
