24 PCB007 MAGAZINE I APRIL 2018 Most of the technology regarding signal pro- cessing in PCBs is available in the consumer industry and must be transferred to the auto- motive industry, with its necessary quality and reliability requirements. Regarding power elec- tronics, new PCB developments are necessary to enable volume production of power elec- tronics for a big market. Until now, power elec- tronics were mainly produced only with low production volume. The PCB is a crucial part in these electronic systems, and considering high-speed require- ments, is not just a connecting part between the devices. Special attention must be drawn to the failure modes in PCBs which can result in shorts or opens. In an autonomous car, which is powered by several hundred volts, the PCB must be understood very well to guar- antee a reliable service. Figure 5 shows typi- cal loads on the PCB during production and product lifetime, with selected critical failure modes. Figure 6 shows an organizational chart of required PCB properties for automotive elec- tronics. Automotive Requirements for Future Electronics The automotive-specific requirements for the PCB are driven by the environmental load such as temperature, humidity and vibration- Automotive Electronics | AE/EAI1 | 12/10/2017 © Robert Bosch GmbH 2017.
