This paper presents the characterization of electronic components from Printed Circuit Boards (PCBs) and the comparison with the characterization of the printed circuit board without its parts. The question that guides the research is about the possibility of developing a methodology for processing that covers not only the PCBs but also its electronic components. This process is possible through the physical dismantling of the computer, printed circuit board removal, separation of their

After the mechanical processing, the chemical steps start with the analysis of x-ray Fluorescence (FRX) that determines the types of metals contained in each granulometric fraction, leaching in aqua regia, which separates the ceramic and polymeric materials of metals, and precipitation of metals using the method of reduction using laboratory, aluminum that retrieves the metals so that they can be reused. The viability of the research is indicated by the scanning electron microscopy analysis, which reveals what kinds of metals have been recovered.
