Explanation for Traceability of the Easy Automotive Modules

The automotive components and systems are becoming more and more complex. Furthermore, the number of components in a car also increases steadily and thus the likelyhood of a product failure. It is obvious that safety should never be compromised. But also product failures in non-safety critical functions lead to displeased end-customers and a lost of reputation in case of public product recalls, which is often not quantifiably in cost. Therefore, it is an absolutely must in the automotive industry to avoid product failures. Infineons answer is a living automotive excellence program, which includes e.g. the Zero Defect Production. In order to support the lowest possible FIT (failure in time) rate in the field, preventive measures for avoiding product failures as well as reduction of failures in the field are demanded. One possibility is a seamless traceability of the production materials and manufacturing processes, which can also avoid product piracy, as materials, processes and equipment can be traced back to the origin. The Easy Automotive power modules have implemented a considerably set of traceability measures. These are explained in this application note. But traceabily must not be aborted after the modules are shipped to the customer. Therefore, hints for continuing a seamless traceability on the customer side are given as well as the identification of module-IDs, tray-IDs, which is the key to achieve such a tracing functionality. Therefore, module and tray labels are explained, that the customer easily finds the right numbers and IDs for the traceability concept.
