Description: 
"Tacky2"- 71°C Thermaphase compound is precoated onto a 2-mil Aluminum substrate. This material is slightly adhesive at room temperature. It can be temporarily adhered to heat sink surfaces by simply pressing it firmly onto the heat sink. When the temperature of this material exceeds the reflow temperature, the compound reflows and fills all of the pores of both electronic component and heat sink to form a very low thermal resistance interface. The material requires only 10psi of closure force to flow when in the molten state and creates a very thin thermal interface. This material is thermoplastic. It can be reflowed and solidified innumerable times. After initial reflow and when re-solidified by cooling to a temperature below the phase temperature, this material has an adhesive strength of 25psi. Simply heating above the phase change temperature for component removal can break the adhesive bond. This material can replace thermally conductive epoxies in most applications. It is not a thermosetting material like epoxy. It can operate either in the solid or reflowed state.

On special order this product is available on other types of metal foils. Ask ORCUS for details.

The applications of Thermafoil 71°C "Tacky2"are the same as for Thermafoil 52°C. It is easy to apply to a heat sink by simply pressing the Thermafoil "Tacky2" part onto the heat sink at room temperature. It does not require heat to temporarily adhere the pad to the heat sink. Use "Tacky2" is any application that requires a low thermal resistance path between electronic component and heat sink and the convenience of room temperature application of the interface to the heat sink surface. Thermafoil "Tacky2" is thermoplastic. When reflowed under low closure force it flows into all surface imperfections of component and heat sink. When re-solidified it adheres the component to the heat sink. For component removal, simply reheat above the phase change temperature.
