Tungsten alloy carrier plates heat sink heat resistance sheet used in thermal mounting plates etc...
2.Excellent hermeticity
3.Excellent flatness, surface finish, and size control
4.Semi-finished or finished (Au plated) products available
5.CTE closely controlled to match ceramics (Al2O3, BeO), semiconductor (Si), metals like Kovar, etc.
1.Used as high temperature resistance in electronic products and Auto-Engines. Like Computer generates vast amounts of heat, which results in the slow of speed.Tungsten alloy heat sink can solve this problem.
2.Used in applications such as optoelectronics packages, Microwave Packages, Packages, Laser Submounts, etc.
3.Used as heat sink pieces and encapsulation shell.
4.Used in thermal mounting plates, chip carriers, flanges, and frames for RF, microwave millimeter wave packages like LDMOS FET; MSFET; HBT; Bipolar; HEMT; MMIC, light emitting diodes and detectors, laser diode packages like pulse, CW, single emitter, bars and complex carriers for optoelectronics amplifiers, receivers, transmitters, tunable Lasers.
