Environmental Assessment of a New Developed Camera System for Automotive Application

Embedding technology is an advanced electronic packaging method which allows assembling electronic components not only on the surface but also inside the volume of the printed circuit board material. The resulting higher packing density of assemblies leads to drastic miniaturisation of the package and reduces the expenditure on materials. This work compares the environmental performance of a conventional and a new developed rear camera system for automotive application. The life cycle assessment method is ReCiPe Midpoint (H), 2014, based on the ecoinvent 3.3 database. The considered characterisation categories are Climate change (CC), Human toxicity (HT), and Terrestrial ecotoxicity (TE). The new demonstrator camera shows in all characterisation categories a reduction of the environmental impact between 55 % and 60 % within the defined system boundaries, compared to the traditional multilayer PCB assembly, and a mass reduction of 31 %.
