The recorded value includes interfacial thermal resistance. These values are provided for reference only. Actual application performance is 52C phase change temperature directly related to the surface roughness, flatness and pressure applied. Unsupported 1) This is the measured thermal conductivity of the Hi-Flow coating. It represents one conducting layer in a three- layer laminate. The Hi-Flow coatings are phase change compounds. These layers will respond to heat and pressure induced stresses. The overall TYPICAL APPLICATIONS conductivity of the material in post-phase change, thin filmproducts is highly dependent upon the heat and pressure applied. This characteristic is not accounted for in ASTM D5470. Processor lid to heat sink Please contact Bergquist Product Management ifadditional specifications are required. FBDIMM to heat spreader 2)The ASTM D5470test fixture was used and the test sample was conditioned at 70C prior to test. The recorded value includes interfacial thermal resistance. These values are provided Processor die to lid or heat sink for reference only. Actual application performance is directly related to the surface roughness, flatness and pressure applied. BERGQUIST HIFLOW THF 3500U is a thermally conductive phase change material which is applied in tabulated pad form . In the application the easy to use material undergoes a phase GENERAL INFORMATION change at 52C. For safe handling information on this product, consult the Safety Data Sheet, (SDS). After phase change, BERGQUIST HIFLOW THF 3500U wets out the thermal interfaces producing a very low thermal Not for product specifications impedance .
