Plastic Electronic EnclosuresA technique for fabricating an improved electronic enclosure. The electronicenclosure is made of graphite fibers dispersed directionally (non-homogeneous) in an absolac/polycarbonate (ABS/PC) resin mix, of which the composition is molded to form the the plastic enclosure. The graphite concentration is highest along the interior surface of the enclosure to provide improved heat transfer, as well as adequate EMI/RFI shielding. However, the graphite concentration decrease along the thickness, wh |
