Tungsten-rhenium Alloy Electronic Packaging Sheet Metal Injection Molding MIM Parts

Use

Electronic packaging sheets are mainly used for heat exchange in refrigeration and air conditioning systems and automotive radiators (heat exchangers). Electronic packaging sheets are also used in thermal management electronic products, often in computer central processing units (CPUs) or graphics processors.

Function

Packaging sheets also help cool electronic and optoelectronic devices, such as high-power lasers and light-emitting diodes (LEDs), and their physical design is conducive to cooling the surrounding fluids, such as the increase in the surface area of ​​air contact. Accelerating air circulation speed, material selection design and surface treatment thermal resistance, that is, thermal performance, electronic packaging sheets, factors that affect the design. In computer central processing units (CPUs) or graphics processors, electronic packaging sheets for these basic attachment methods and thermal interface materials can affect the final junction and dissipate the temperature of the processor (s). Thermal silicone (also known as thermal conductive silicone grease) is added to the heat sink to help its ability to dissipate heat. Experimental property values ​​can determine the heat dissipation performance of an electronic packaging sheet.

Material Advantages

Electronic packaging materials utilize the low expansion characteristics of tungsten and the high thermal conductivity of copper. Its thermal expansion coefficient and electrical conductivity can be changed by adjusting the composition of the material, which provides convenience for the use of the material.

Other Uses Of Materials

1. Resistance welding electrode: It combines the advantages of tungsten and copper, is resistant to high temperature, arc erosion, high strength, high specific gravity, good electrical and thermal conductivity, easy to cut, and has sweating and cooling characteristics. Due to the high hardness, high melting point and anti-adhesion characteristics of tungsten, it is often used as a projection welding and butt welding electrode with certain wear resistance and high temperature resistance.

2. Electric spark electrode: When the mold made of tungsten steel and high-temperature resistant superhard alloy needs to be electro-etched, the ordinary electrode has a large loss and a slow speed, while the high electro-corrosion speed of tungsten copper, low loss rate, precise electrode shape, and excellent processing performance can ensure that the accuracy of the processed parts is greatly improved.

3. High-voltage discharge tube electrode: When the high-voltage vacuum discharge tube is working, the contact material will increase the temperature by several thousand degrees Celsius in a few tenths of a second, and the anti-ablation performance, high toughness, good electrical and thermal conductivity of tungsten copper provide the necessary conditions for the stable operation of the discharge tube.
