The combination between the high volume of waste electrical and electronic equipment (WEEE) and the increased planned obsolescence makes it necessary to think about alternative ways to dispose of these wastes, such as recycling followed by metal recovery, without affecting the environment and human health. In order to do so, it is essential to understand the nature of the waste-constituent materials. Printed Circuit Boards (PCB) are important representatives of WEEE, since they are found in most electronic equipment, such as computers. PCB heterogeneous composition comprises high metal contents, with some being precious metals, justifying the application of recycling processes to recover them. The aim of the present study is to investigate the characterization of memory boards from obsolete computers for the subsequent recovery of precious metals. Results indicated that the memory board mass comprised 18.9% metals, 48.4% ceramics, and 32.7% polymers. Copper was the most expressive metal, accounting for 13.83% of the board mass, while precious metals such as silver and gold represented only 0.053% and 0.069% of the board mass, respectively; however, their high market value justifies their recovery.
