From ordinary to excellent: How can copper enable innovation in electronic devices?

In the rapid development of electronic equipment, copper from a common basic material, gradually transformed into a key force to promote the innovation of electronic equipment, help electronic equipment to achieve the leap from ordinary to excellent. Its unique physical and chemical properties make it play an irreplaceable role in every key link of electronic equipment, and inject a steady stream of vitality into the performance improvement, function expansion and appearance design innovation of electronic equipment.

Optimize the basic performance and lay an excellent foundation

Electronic devices require high speed and stability for signal transmission, and copper's excellent electrical conductivity makes it an ideal material for building efficient signal transmission pathways. In the early electronic equipment, copper has been widely used in wire and cable, to ensure the stable transmission of power and signals. With the development of technology, very large scale integrated circuits have become the core of electronic devices, and copper interconnects have played a revolutionary role in this. In the face of the growing

demand for signal transmission, the traditional aluminum interconnect has high resistance and prominent electron migration problems, which limits the chip performance. Copper interconnect with low resistance characteristics, effectively reduce the signal transmission delay, according to research shows that the use of copper interconnect chip, signal transmission delay can be reduced by about 30%, greatly improve the chip data processing speed, for computers, smart phones and other equipment to lay the foundation for high-performance operation. In the signal transmission line of 5G communication base stations, copper cable with its low loss and high bandwidth characteristics ensures the high-speed and stable transmission of 5G signals, so that high-traffic applications such as high-definition video and cloud games can run smoothly, and bring people the ultimate network experience.

If the heat generated during the operation of electronic equipment cannot be dissipated in time, it will seriously affect the performance and life of the

equipment. The good thermal conductivity of copper makes it an excellent heat dissipation material. On the core heating components such as computer cpus and Gpus, the copper radiator quickly transfers heat to the cooling fins by tightly

fitting the surface of the chip, and then dissipates heat into the air with the help of cooling devices such as fans. The experimental data show that the operating temperature of the core components of the computer using the copper radiator is reduced by 5-10 ℃ compared with that of the equipment using other materials, which ensures that the equipment can still work stably under high load operation and effectively extends the service life of the equipment. In mobile devices such as mobile phones, copper foil heat sink, soaking plate and other copper based heat dissipation components also play an important role in ensuring the stability of the performance of the equipment in the process of long-term use.

It helps the manufacturing of new components and expands the functional boundaries

In the field of sensor manufacturing, copper provides strong support for the development and application of new sensors. For example, in high-precision pressure sensors, copper-based alloy elastomeric elements can accurately sense

pressure changes and convert them into electrical output. Its good elasticity and electrical conductivity ensure that the sensor has high sensitivity and fast response characteristics, and is widely used in automotive electronics, industrial control and other fields. In the biosensor of wearable devices, copper electrodes are used to collect human bioelectrical signals. With its good biocompatibility and

conductivity, it can stably and accurately obtain ECG, EEG and other signals, providing key support for the realization of health monitoring functions.

In terms of energy storage components, the application of copper-based materials has brought new breakthroughs in improving battery performance. In lithium-ion batteries, copper foil acts as a negative fluid collector, carrying out the heavy task of collecting and conducting electrons. Its high conductivity and good mechanical properties ensure the efficient and stable operation of the battery in the charge and discharge process. At the same time, researchers have developed a new type of copper-based electrode material by modifying the copper-based material, which is expected to improve the energy density and cycle life of the battery. For example, copper-lithium-cobalt composite electrode materials have shown higher specific capacity than traditional electrode materials in laboratory tests, which brings hope for the improvement of battery life of electric vehicles, mobile power supplies and other equipment.
