Quality assurance
We maintain the highest standards of quality throughout the assembly process. All circuit board assemblies are barcoded and tracked through the various manufacturing steps. Our team analyzes the data collected at each stage during production to continually enhance and improve the process.
PCB inspection
A rigorous first article inspection process is performed on each build, complemented by a robust NPI procedure for new products. We produce build documents and machine programs from your information, as well as make recommendations for your designs to streamline your products’ manufacturing process.
Our series of inspections during the PCB assembly process are designed to ensure product quality, reliability and functionality, and to reduce field failures.
