China's capacitor market size will reach 13.84 billion

The power of breaking hair is precipitated everywhere, just like the super capacitor industry that has been quietly cultivated in the industry, waiting for the arrival of "spring. On January 6, the "China Supercapacitor Industry Annual Conference and Application Exhibition" was held in Tianjin. Gao Bo, Secretary-General of the Supercapacitor Industry Alliance, said in an interview with a reporter from China Electric Power News at the meeting: "Supercapacitors have fast charging and high power., Long cycle life, strong temperature adaptability, environmental protection and pollution-free advantages. With the further development of the application market, we firmly believe that supercapacitors will become an important member of the energy storage family."

Diode market competition is white-hot

As the world's largest diode device market, China's market demand is increasing year by year. With the continuous transfer of the international diode industry and the continuous participation of domestic enterprises, the competition in China's rectifier diode market will become increasingly fierce, especially in the low-end market. Small and medium-sized diode companies will be eliminated in the future due to their low anti-risk ability.

Some basic knowledge of patch components

Now there are more and more patches for welding machine circuit boards because of its high efficiency and low cost. At present, the vast majority of welding machine maintenance personnel on the patch is still very strange. They have already become accustomed to plug-in components and are generally repulsive to patch welders. The headache of the patch is that the component is too small, there is no identification model on the component, the circuit board of the patch is too dense, and the patch component is unfamiliar. These factors have caused the patch welder to need to change the board to get it done, and there are very few people who can skillfully repair the patch circuit board. Welding machine circuit board patch is a major trend, maintenance personnel are faced with the urgent need to upgrade knowledge. Survival of the fittest, those who can't keep up with the pace of upgrading, the road will become narrower and narrower until they are eliminated. Here are some basics about patch components.
