Tungsten Copper Heat Sinks For Thermal Management,Copper Tungsten Heat Sink W60Cu40 heat sinks
Copper tungsten is the pseudo-alloy who has the advantage of the high thermal conductivity of copper and the low coefficient of thermal expansion of tungsten. It is easy to adjust the CTE( coefficient of thermal expansion)by use the different ratio of copper and tungsten.Tungsten copper sheets have very high in plane conductivity provide by layers of copper and low thermal expansion provided by the inner layer of molybdenum. These laminated sheets have the ability to spread the heat from a concentrated heat source and then dissipate the heat through the layers.
Tungsten copper heat sinks are extensively used as thermal mounting plates, chip carriers, flanges, and frames for RF, light emitting diodes and detectors, laser diode packages like:
pulse, single emitter, bars and complex carriers for optoelectronics amplifiers, receivers, transmitters, tunable lasers, etc.
