Description
Technical field
The present invention relates to a kind of heat sink material, specifically, relate to a kind of heterogeneous liquid metal heat interface material containing zinc and preparation method thereof.
Background technology
Microelectronics is towards superpower, high speed, and the trend development such as miniaturization, and the high flux of heat that related device produces must be in time and is removed efficiently, and electron device working-surface temperature is maintained under its safe working temperature.Electronic component works long hours at high temperature, understands the serviceability of serious reduction electron device, has a strong impact on work-ing life and the stability of device.Along with microelectronics high speed development, electronic radiation product constantly presents variation by innovating.Heat interfacial material is for filling gap between heating element and radiator, plays the medium that improves heat-transfer effect.Conventional heat interfacial material is silicone grease, and after adding the metal or ceramic particle of high thermal conductivity coefficient, heat transfer coefficient can reach 2W/mK left and right.Silicone grease is generally used for working temperature 60
othe chip device of about C, and this material can after Long contact time air, produce aging, heat-transfer effect thereby can sharply decline along with the time.Liquid metal has high thermal conductivity, generally can maintain 80W/mK left and right.The surface tension and the wetting ability that rely on liquid metal excellence, liquid metal can be filled the high efficiency and heat radiation object that hole between heating element and radiator reaches microelectronic device completely.Liquid metal is for the heat-transfer capability of essential domain, and for example LED industry and pc domain, more and more cause extensive concern, and the Commercialization Trends of related products also comes with obvious.
General liquid metal thermal interface material, even as multicomponent material, has the characteristic melting at a certain temperature.When working temperature is greater than temperature of fusion, whole liquid metal thermal interface material will occur with the form of complete liquid state.Completely the liquid metal thermal interface material of melting overflows from hot interface under may be in working order, thereby makes microelectronic device and circuit card short circuit.For the interface that liquid metal is possible, omit phenomenon, in order to adapt to the day by day harsh radiating requirements of microelectronic element, in the urgent need to there will not be the appearance of the heat interfacial material of interface omission.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of heterogeneous liquid metal heat interface material containing zinc with the excessive effect of resistance and preparation method thereof is provided.
To achieve these goals, the present invention adopts following technical scheme:
A heterogeneous liquid metal heat interface material, is comprised of indium, bismuth, tin and zinc, and its weight percentage is: 30-40% bismuth, and 10-20% tin, 10-20% zinc, surplus is indium.
The preparation method of above-mentioned heterogeneous liquid metal heat interface material, comprises the steps:
(1) according to formula, claim metallic substance, utilize plumbago crucible and vacuum induction furnace alloy to be carried out under vacuum to melting and homogenizing processing, and alloy melt is cast into the foundry goods that thickness is 1mm;
(2) roughing: alloy-steel casting is put into roughing mill, and lubricated by ROLLING OIL, the passage of depressing of roughing is: 1mm-0.4mm-0.2mm-0.1mm; In roll: during the woollen after roughing is carried out, roll, lubricated by ROLLING OIL, under middle roll compacting, passage is: 0.1mm-0.06mm; Finish rolling: by material after rolling drop into finishing mill, by ROLLING OIL, be lubricated, the passage of depressing of finish rolling is 0.06mm-0.04mm;
(3) utilize organic solvent to carry out de-oiling processing the Alloy Foil obtaining, afterwards the Alloy Foil making is tailored into the size of design width packing warehouse-in through cutting machine.Organic solvent is preferably acetone.
Compared with prior art, the present invention has following beneficial effect:
Traditional liquid metal thermal interface material can only melt at single temperature, and the excessive liquid metal that may cause of mobility when liquid overflows inside and outside heating element and radiator hole, finally causes the short circuit of electron device.The heterogeneous structure liquid metal thermal interface material of the present invention's design is quad alloy, has solid-state structure completely under room temperature and rolling temperature.Under working temperature in liquid-solid state.In working order, the content of solid phase is in 60% left and right.There is on a large scale the state that keeps liquid-solid phase in working temperature, can fully suppress the mobility of alloy foil sheet with low-melting point melted by heating, eliminate the problem that drop leaks.In addition, the thickness of heat interfacial material maintains near 0.04mm, can further utilize the surface tension of liquid phase to reach the effect of Drain Resistance.
