Wafer substrate made of molybdenum, molybdenum copper and tungsten copper materials: In order to make the?LED lamp durable, it must be equipped with reliable and robust components. With our molybdenum, MoCu and WCu wafer substrates, LED chips can easily reach 100,000 hours of service life.
Nickel-plated gold-plated molybdenum-copper substrate microelectronic electronic sealing sheet
Copper-molybdenum-copper alloy heat sink material is a composite material of tungsten and copper. It has both low expansion characteristics of tungsten and high thermal conductivity of copper. Especially valuable, its thermal expansion coefficient and thermal conductivity can be adjusted by adjusting the material. The composition of the composition (in terms of terms, its performance is tailorable), thus bringing great convenience to the application of the material. The copper-molybdenum-copper alloy heat sink material produced by our company can form a good thermal expansion match with the following materials:
(1) Ceramic materials: Al2O3 (A-90, A-95, A-99), BeO (B-95, B-99), AlN, etc.;
(2) Semiconductor materials: Si, GaAs, SiGe, SiC, InGaP, InGaAs, InAlGaAs, AlGaInP, and AlGaAs.
(3) Metal materials: Kovar alloy (4J29), 42 alloy, etc.;
The characteristics and performance of our company's copper-molybdenum-copper (Cu/Mo/Cu) alloy heat sink material:
Copper-molybdenum-copper (Cu/Mo/Cu) is a sandwich structure consisting of two sub-layers - copper (Cu) - a core layer - molybdenum (Mo), which has an adjustable coefficient of thermal expansion, high thermal conductivity and its high The characteristics of strength.
