    Abstract: A printed wiring board has thereon an electronic component having a heat radiation pad, and an electrolytic capacitor provided for the electronic component. The printed wiring board further has thereon another electronic component having another heat radiation pad and exhibiting a higher heat value than that of the electronic component, and another electrolytic capacitor provided for the other electronic component. The heat radiation pad of the electronic component, a ground terminal of the electrolytic capacitor, the other heat radiation pad for the other electronic component, and another ground terminal of the other electrolytic capacitor are connected by using a ground conductor. In the ground conductor, a thermal resistance between the other heat radiation pad and other ground terminal is lower than the thermal resistance between the heat radiation pad and the ground terminal.

    Abstract: Present thermal solutions to conduct heat from pluggable optical modules into heat sinks use a metal heat sink attached with a spring clip. The interface between the pluggable module and the heat sink is simple metal-on-metal contact, which is inherently a poor thermal interface and limits heat dissipation from the optical module. Heat dissipation from pluggable optical modules is enhanced by the application of thermally conductive fibers, such as an advanced carbon nanotube velvet. The solution improves heat dissipation while preserving the removable nature of the optical modules.
