What Are the Manufacturing Processes of Tungsten Copper Heat Sinks?

Tungsten copper heat sinks are indispensable components in various industries, known for their exceptional thermal conductivity and mechanical strength. The manufacturing processes behind these heat sinks are complex yet precise endeavors, involving several key steps to ensure the final product meets stringent performance requirements. 

Material Selection:

The manufacturing journey of tungsten copper alloy heat sinks begins with the careful selection of raw materials. Tungsten and copper powders, typically in predetermined ratios, are chosen based on their purity and consistency. These materials must meet strict quality standards to ensure the final product's integrity and performance.

Mixing and Blending:

Once the raw materials are selected, they undergo a meticulous mixing and blending process. This step involves combining tungsten and copper powders in precise proportions to achieve the desired composition and uniformity. Specialized equipment such as ball mills or mixers are utilized to ensure thorough mixing and homogeneity of the blend.

Compaction:

After blending, the mixed powders are subjected to compaction to form a green compact or preform. Compaction is typically achieved using hydraulic or mechanical presses, where the powder blend is compressed under high pressure into a specific shape and size. The compacted preform serves as the precursor for the subsequent processing steps.

Sintering:

Sintering is a critical stage in the manufacturing process of tungsten copper alloy heat sinks, where the green compact undergoes a controlled heating process in a furnace. During sintering, the compacted powder particles are fused together through diffusion, resulting in a solid, dense structure. The sintering parameters, including temperature, time, and atmosphere, are carefully controlled to achieve optimal material properties, such as density and microstructure.

Machining and Finishing:

Once sintering is complete, the sintered tungsten copper material undergoes machining and finishing operations to achieve the final dimensions and surface quality required for the heat sink. Precision machining techniques such as milling, turning, and grinding are employed to shape the material according to the desired specifications. Additionally, surface treatments such as polishing or coating may be applied to enhance the heat sink's performance and durability.

Quality Assurance:

Throughout the manufacturing process, stringent quality control measures are implemented to ensure the final product meets the required standards and specifications. Non-destructive testing methods such as visual inspection, dimensional analysis, and thermal conductivity testing are employed to verify the integrity and performance of the tungsten copper heat sinks.

Tungsten-copper Composite Materials to Support the 5G Technology

Tungsten-copper composite material is a kind of pseudo-alloy composed of tungsten and copper elements. It combines the high melting point, high density, and low coefficient of thermal expansion of tungsten with the high electrical conductivity and thermal conductivity of copper, providing strong support for the rapid and efficient transmission of 5G technology.

Electronic packaging materials are a kind of substrate material, whose main functions include carrying electronic components and their interconnections, providing mechanical support for these components, ensuring sealing environment protection, and effectively dissipating the heat generated by electronic components. Additionally, it must also have excellent electrical insulation performance as a sealant for integrated circuits. Tungsten-copper composite materials, with their unique physical and chemical properties, are widely used in electronic packaging materials.

In electronic packaging materials, the application of this composite materials mainly manifests in the following aspects: Firstly, the high melting point and high density of tungsten ensure that the material can maintain stable performance even in high-temperature environments. Secondly, the high electrical conductivity and thermal conductivity of copper ensure fast signal transmission and efficient heat dissipation of the equipment. Thirdly, the low coefficient of thermal expansion of the composite materials enables them to have minimal dimensional changes when the temperature changes, which is crucial for maintaining the stability and reliability of the packaging structure.

Tungsten-copper composite materials can be produced using the infiltration method: Tungsten powder is pressed into green compacts with a certain shape and strength, then sintered at high temperatures to remove binders and other impurities from the green compacts, while forming a certain bond between tungsten particles, forming a tungsten skeleton with a certain porosity. Next, molten copper metal is injected into it. Under the capillary action, the copper melt flows through the interstices between the tungsten particles, filling and wetting the pores of the tungsten skeleton. Finally, after appropriate cooling, the copper and tungsten skeleton are tightly combined to form dense tungsten-copper alloy.
