FIELD OF THE INVENTION
The present invention relates to an adhesion material structure and a process method and, more particularly, to a method for manufacturing the adhesion material which combines a metal with a bracket structure of carbon element.
BACKGROUND OF THE INVENTION
In recent years, the pace of high technology industry development is extremely fast, the development of electronic components is toward small volumes and high densities. Relatively, much waste heat is generated and is unavoidable. The performance of the electronic components will be decreased if the waste heat is unable to eliminate appropriately. Therefore, various heat conduction materials are provided to improve the efficiency of heat dissipation.
Each heat dissipation component needs to be connected together to improve the efficiency of heat dissipation after a heat dissipation slip, a heat sink fin and a heat pipe are provided one by one. The connection technique usually uses welding that two components are combined together by using a melted metal.
A conventional arc welding is that current passes a weldment through an electrode to generate high temperature immediately. A crater is melted and is then cooled to weld two components. Referring to FIG. 1, a schematic diagram illustrates a conventional arc welding. The arc welding comprises a welding machine 11, an electrode fixture 12, an electrode 13, a weldment 14, a ground wire 15 and an electrode lead 16. The welding machine 11 is connected to the electrode fixture 12 via the electrode lead 16 and the ground wire 15 is connected to the weldment 14. The electrode 13 is clipped by the electrode fixture 12. Currents provided by the welding machine 11 pass through the electrode lead 16 and reaches the electrode 13 clipped by the electrode fixture 12. Electrons jump between an end of the electrode 13 and the weldment 14 to generate arcs 17 and the remaining currents then return to the welding machine 11 through the ground wire 15 which is connected to the weldment 14. Above procedure is a current loop of the arc welding. The jump pitch may generate higher impedance for the electron current and the arcs 17 are then generated. The electrode 13 is melted through the arcs 17 and the melted particles are dripped on the weldment 14 for welding. The metallic characteristics of the electrode may be changed when the electrode experiences melting, adhering and cooling and then the metal existed between the weldment may cause the thermal resistance for thermal conduction.
Besides, diamonds are well known and have characteristics with the highest hardness, the fastest heat conduction, and the widest refraction range. Diamonds, therefore, are always one of more important materials in engineering due to the excellent characteristics. The thermal conductivity of diamonds at the normal atmospheric temperature is five times more than copper. Moreover, the thermal expansion factor of diamonds at high temperature is very small that shows the excellent efficiency of heat dissipation. The feature may help people to differentiate the adulteration of diamonds. In the prior art, many technologies and manufacture methods have been developed to make diamonds. The direct decomposition for hydrocarbons is the most familiar method like Microwave Plasma Enhance Chemical Vapor Deposition (MPCVD) and Hot Filament CVD (HFCVD). By the aforesaid methods, polycrystalline diamond films can be deposited. The characteristic of the polycrystalline diamond films is same as the single crystal diamonds.
Accordingly, an adhesion material and corresponding manufacturing process are provided to satisfy the demand of thermal conduction and the welding technique simultaneously.
