UsageApplication LED Bulb Heat Sink Compound, Thickness 15 mm, Material Aluminum

Descriptionpure white, Soft, Heat sink paste with marked thermal conductivity. Electrically insulaing. Applicationmetroark heat?? sink compound is used especially in semiconductor technology as a heat sink paste. Wherever it is important to have good heat transfer from a semiconductor to a you'll find, Cooling element it to be advisable to possess a thin coating of metroark heat?? sink compound. In the assembly e. G. Diodes, Transistors and, Of semiconductors thyristors, Microscopic elevations exist on the mating surfaces of the semiconductor ant the cooling surface if they have not been ground and polished. When these surfaces are placed together, A firm metal, To metal contact will result only where there are these elevations. 40, 60% of The top layer is thus not in based on, Direct contact the roughness. This means that the hollow spaces in between these elevations are filled with air, Which has relatively poor thermal conductivity. By coating the contact surfaces with metroark heat?? sink compound, The thermally insulating air is replaced by the heat sink silicone paste when the semiconductor is screwed on. The heat transfer efficiency of metroark heat?? sink compound is about 20 times better than that of air. Practical experience has shown that by using metroark heat?? sink compound, The heat transfer resistance from the semi, Conductor housing to the cooling elements is reduced to half. Metroark heat?? sink compound can be applied with a brush, Spatula or by screen printing. Best results are?? achieved when an uniform, Thin coat is applied to the mating surfaces. Paste squeezed out when the semiconductor is screwedon should be removed. ??product data propertytest methodunitvaluecolor????whiteunworked penetrationis 76481975is 76481975150, 220drop point at 250 degreecis 5071970?? degreec ????nonebleed percentis 76481975?? % ??max. 3evaporationis 76481975?? % ??max. 3operating temperature range???? degreec ????, 30 to, 200dielectric strength??kv/mm10, 15????
