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 conductivity of the material in post-phase change, thin film products is highly dependent upon the heat and pressure applied.This characteristic is not accounted for in ASTM D5470. Please contact Bergquist Product Management if additional specifications are required. 2) The ASTM D5470 test 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 for reference only. Actual application performance is directly related to the surface roughness, flatness and pressure applied. Typical Applications Include: * Spring / clip mounted * Power semiconductors * Power modules Configurations Available: * Sheet form, die-cut parts and roll form * With or without pressure sensitive adhesive Building a Part Number 0.005 Standard Options - AC - 1212 - NA Section E - Section D Section A HF625 Section C Hi-Flow 625 is tack-free and scratch-resistant at production temperature and does not require a protective liner in most shipping situations. The material has the thermal performance of 2-3 mil mica and grease assemblies. 25 2.26 Section B Hi-Flow 625 is a film-reinforced phase change material.The product consists of a thermally conductive 65C phase change compound coated on PEN film. Hi-Flow 625 is designed to be used as a thermal interface material between electronic power devices that require electrical isolation and a heat sink.The reinforcement makes Hi-Flow 625 easy to handle, and the 65C phase change temperature of the coating material eliminates shipping and handling problems.The PEN film has a continuous use temperature of 150C. 10 TO-220 Thermal Performance (C/W) NA = Selected standard option.
