Abstract:
An information handling system and/or peripheral device includes a printed circuit board having at least one prepreg substrate coupled to at least one bio-based substrate to support operation of electronic components, such as mouse position sensor and scroll wheel rotation sensor, and having a layer of graphene between the prepreg substrate and the bio-based substrate. At end of life, the bio-based substrate is removed from the prepreg substrate, such as by melting of the biobased material, so that the prepreg substrate can be reused. In one embodiment, the prepreg substrate supports power and ground planes that bio-based substrates couple over so that the prepreg substrate can be reused along with the power and ground planes by coupling updated bio-based substrates over the reused prepreg substrate.
