Abstract :With the constant demand of automotive industries for embedded electronic devices in order to employ them in vehicles that needs constant monitoring and management of their energy systems, analog voltmeters stands out in this kind of application by their measurement efficiency and driver’s assistance. This electronic device is often used for variable’s controlling in fields where requires total measurement preciosion, such as: automotive ebedded systems,  process control, electrical machenary testing, electronic diagnosis and so on. The current work was designed to the development of an analog voltmeter PCB’s design layout based on DFMEA insert ignore into journalissuearticles values(Design Failure Mode and Effects Analysis); methodology, to avoid potential failures during design conception. The confection process of those PCB’s layouts begins with the analysis of two original circuits in AutoCAD, where the main problem verifyed was the alterations to be done in the circuits due the layer’s distribution scenario. This problem was solved through SMT components re-adjustment applying DFMEA methodology. In the application of this meyhodology, the percentage of  potential failures was about to 61% to the first circuit and 38% to the second circuit. This results idicates that the application of DFMEA in PCB’s design layout is highly efficient to detect, identify and classify the risk and severity of potential failures during the project development.               Keywords- Vehicle electronics, embedded systems, DFMEA, PCB design, instrumentation, failure reduction
