11. Thermally conductive tape is one of the most cost-effective heat sink attachment materials. 12. The epoxy bond between the heat sink and component is semi-permanent / permanent. 13. These were linear regulators which commonly were mounted on heat sinks . 14. Without a ceramic package, the VIC-II required the use of a heat sink . 15. The idea of thermal resistance of a semiconductor heat sink is an approximation. 16. The heat sink of a Stirling engine is typically the ambient air temperature. 17. Many power amplifiers feature internal fans to draw air across their heat sinks . 18. This in turn is used to select an appropriate heat sink if necessary. 19. Natural convection requires free flow of air over the heat sink . 20. The sole's grid pattern functions as a heat sink , through which heat dissipates.
