Copper Tungsten Heat Sink,CuW Base Plate, W90Cu10 Heat Sinks
Copper Tungsten Heat Sink 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.
Feature:
High thermal conductivity
Excellent hermeticity
Excellent flatness, surface finish, and size control
Semifinished or finished (Ni/Au plated) products available
CTE closely controlled to match ceramics (Al2O3, BeO), semiconductor (Si), metals like Kovar, etc.
