Abstract Scope Industry development leads to an arising environmental and economic problem: the increase of e-waste’s generation. Main cause is the combination between the diversification of electric and electronic device’s applications and programmed obsolescence, which promotes a high generation the so-called waste electrical and electronic equipments (WEEE). Printed circuit boards (PCBs) are present in almost all WEEE and their heterogenous composition have a considerable amount of metals, including some precious ones. Recycling is an environmental friendly purpose for PCBs’ destination, combined with economic advantage from recovery of metals. The choice of correct process to recycling depends on the composition of the PCBs, so the correct characterization is required. This work aims to characterize two different PCBs from obsolete computers: motherboard and memory board, concluding that they have 35.5 and 18.92% of metals, respectively, including precious metals. Also, memory board has 0.122% of these precious metals to the detriment of 0.047% from motherboard.
