Testing Technology


No circuit board or system leaves ERNI without a thorough final inspection of all connections and components. All ERNI production sites are equipped with identical manufacturing and testing technology. This way, we can guarantee consistently high standards worldwide while maintaining superb product flexibility.

We do not have to compromise the quality of any of our processes, thanks to a full-scale testing regime that starts at the design stage and extends right into production. The requirements stipulated for connector systems are the driving force behind ERNI’s quality assurance concept. Our company philosophy is that quality is paramount, and that a zero-error production target is entirely feasible given ongoing revisions and continuous improvement. Our system is required to meet universal guidelines such as CECC 00114T1, with EN 100 114T1 as well as DIN EN ISO 9000.

For both the design and production of backplanes, electronic components, and complete systems, we offer full-scale development from the initial concept right through to the start of production, including documentation and rational testing. At ERNI, all of the manufacturing processes (pressfitting, installation, selective soldering, connection testing, and functional testing) are completed using the highest quality standards. Every component and assembly is checked individually. We offer in-circuit testing (ICT) and functional testing, in addition to automated optical inspection (AOI). We develop specific testing software in close communication with the customer and manufacture our own testing adapters in-house.
