PCB Technical - For PCB factory ceramic circuit boards

The lithium-ion batteries in the PCB factory are extremely sensitive to temperature. If the temperature is too low, the lithium-ion battery cannot work. The temperature is too high. Think about the tragedy of Samsung. The charging and discharging of lithium-ion batteries is a chemical reaction process. Under a calm surface, lithium ions run back and forth between the positive and negative electrodes. When a lithium ion battery is charged, the lithium atom of the positive electrode loses electrons and is oxidized to lithium ions. The lithium ion enters the negative electrode through the electrolyte and obtains an electron, which is reduced to lithium atoms. When discharging, the process is reversed. In addition, in order to prevent the positive and negative electrodes of the battery from directly touching and short-circuiting, the battery uses a separator with fine pores to separate the positive and negative electrodes.

Lithium battery flatulence, high temperature, explosion and other problems are usually related to overcharging, overdischarging and high current, and the three will cause damage to the battery. These three problems are very common, and ultra-low temperature environments are rare, but for ultra-high temperatures, it is simply not too easy for electrical appliances with more and more power. So how to obtain a stable current and how to dissipate heat is very important. At this time, I have to talk about our ceramic circuit boards.

In PCB design, the ceramic circuit board is the circuit board with the highest thermal conductivity currently on the market. I believe everyone will understand that high thermal conductivity of the ceramic circuit board means that it can export all the heat emitted by the lithium-ion battery in time., How do we solve the high current? At this point, in addition to the circuit control system, it also has a great relationship with the circuit board. The higher the precision of the circuit board, the more uniform the circuit, which means that the current flow will be more stable.

Huawei took the lead in launching graphene lithium-ion batteries. The role of graphene in it is pure heat conduction, but graphene has not yet been commercialized. Graphene has a long way to go on the road to commercialization. What we care about is when commercialization will be realized. Only commercialized technologies can benefit users and promote the development of the lithium battery industry. As a very mature product, ceramic circuit boards are still the current king after all.

After all, ceramic circuit boards can stand at the top in this market. The replacement of technology does not make ceramic circuit boards feel threatened, but rather endless power. After all, ceramic circuit boards still have a long way to go, and they can also be almost unlimited. Update iterations. What we have to do is to make good use of it.

Regardless of whether the future is ceramic circuit boards or graphene, it is not our scope of consideration. We only need to know which one can better meet the demand. The life and death of the product is determined by the market. Ceramic circuit boards are not just lithium-ion batteries. A market direction, including LED, aerospace, etc., are some of the most promising industries at present or in the next century. It is foreseeable that ceramiccircuit boards will definitely leave a strong mark on the stage of the history of the electronics industry. .
