identify everything you need to do in order to make such components usable in the automotive industry.” Another task to make sure the systems are safe is to detect any potential failures that might occur through the products’ lifetime. Sanmina’s intelligent testing identifies algorithms that can produce a potential failure while running the initial circuit. “With these processes, we can cycle a component and apply certain signals. By measuring in real-time the responses of the component, including the embedded software, we can determine up to a certain grade how long such a component or a specific component function will last,” explains Enser. It’s also important to have knowledge about the different failure modes of components and to understand their structure, because if anything does fail the supplier needs to run more tests to see what has happened. “The supplier provides you with feedback for example, on electrical over-stress,” said Enser. “The important thing here is that we understand the particular failure phenomenon down in the event electrical over-stress occurs. So you need to know how it happened, and most semiconductor manufacturers have the ability to reproduce such failures. They can tell you the most probable signal or signals that were applied to drive that electrical over-stress, which pins have been loaded with voltage and current, and what time those signals were applied to the pins.”
Considering all of these aspects, the automotive industry still has a long way
to go before we see completely automated vehicles, but we can see developments in ADAS and how they can improve driving safety. Enser concluded: “2017 and 2018 will be a
challenging time for the entire industry. But it is interesting that more and more companies are using EMS services, and we want to make sure that the automotive industry recognises the
value of these services, and learns more about what the EMS industry can bring to this market.”
