The product is a surface-mounted printed circuit board assembly (PCBA), meaning the printed circuit board already includes mounted components; the dataset covers major raw materials, auxiliary materials, energy consumption, and waste generated during the production process. Infrastructure such as manufacturing of production equipment and facility construction is not included within the system boundary of the dataset; the life cycle inventory data is derived from literature sources; PCBA manufacturing includes processes such as substrate preparation, printing, component placement, reflow soldering, testing, and quality inspection.
