An improved circuit board assembly includes a cover or other member disposed adjacent to the substrate and, for example, spaced therefrom so as to define a plenum. Self-aligning heat sinks (or other heat dissipative elements) are spring-mounted (or otherwise resiliently mounted) to the cover and, thereby,...http://www.google.de/patents/US6683787?utm_source=gb-gplus-sharePatent US6683787 - Circuit board assembly with integrated air plenum chamber using self-aligning heat sinks
