This product represents a bare 8-layer printed circuit board (PCB) with an area of 1 m², i.e., a PCB without electronic components, with an average areal density of approximately 5.785 kg/m². The dataset includes major raw and auxiliary materials, energy consumption, air emissions, and waste generated during the production process. Infrastructure such as manufacturing of production equipment and construction of facilities is excluded from the system boundary of this dataset. The life cycle inventory is compiled from data sourced from multiple references. PCB manufacturing involves several processes, including photomask fabrication, inner layer fabrication, copper deposition, outer circuit patterning, plating and etching, printing, surface treatment, shaping, and inspection.
