OEM Fittings Pure Molybdenum Plate / Sheet LED Heat Bases Thickness 0.1mm - 0.3mm
Molybdenum plate can be used as thermal mounting plates, heat bases, chip carriers, flanges, and frames for high-power electronic devices. LED Heat Base is one of important usage of molybdenum sheets.
The thermal conductivity and thermal expansion characteristics of the semiconductor and the base plate must be optimally harmonized to avoid undesired distortions to the semiconductor. The better harmonized the properties are, the better the semiconductor module is to withstand soldering processes involved during manufacture and the temperature cycles that occur during operation. The sketch shows the principle structure of a hermetically sealed electronic package.
Applicatioins of Molybdenum Heat Base:
Advantages of Molybdenum Plates:
High level of thermal conductivity,
Low coefficient of thermal expansion,
Excellent resistance to oxidation at high temperatures,
Excellent resistance to electrochemical corrosion
