Cu/Mo/Cu Heat Sinks For LDMOS Devices
Description:
Cu/Mo/Cu(CMC) heat sink, also known as CMC alloy, is a sandwich
structured and flat-panel composite material. It uses pure
molybdenum as the core material, and is covered with pure copper or
dispersion strengthened copper on both sides. Besides, copper
molybdenum copper heat sink has adjustable coefficient of thermal
expansion, high thermal conductivity, and high thermal stability.
S-CMC is a multi-layered Copper and Molybdenum clad metal, which
has an excellent property both low CTE and high thermal
conductivity. Its higher thermal conductivity compared to other
same kind of materials contributes to highly powered electronic
packages.
Product Properties:
| Grade | Density g/cm3 | Coefficient of thermal Expansion ×10-6 (20℃) | Thermal conductivity W/(M·K) |
| CMC111 | 9.32 | 8.8 | 305(XY)/250(Z) |
| CMC121 | 9.54 | 7.8 | 260(XY)/210(Z) |
| CMC131 | 9.66 | 6.8 | 244(XY)/190(Z) |
| CMC141 | 9.75 | 6 | 220(XY)/180(Z) |
| CMC13/74/13 | 9.88 | 5.6 | 200(XY)/170(Z) |
Application:
Cu/Mo/Cu(CMC) heat sink has similar applications with tungsten
copper heat sinks. It can be used as thermal mounting plates, chip
carriers for microwave, flanges and frames for RF, laser diode
packages, LED packages, BGA packages and GaAs device mounts etc.
S-CMC heat sink can be used in wireless communication packaging,
opto electronics packaging etc.
