　　1. Application fields of 3c lithium battery

　　The application field of 3c lithium battery is mainly concentrated in the electronic product market, and the demand for 3c lithium battery for smart products such as mobile phones, notebook computers, and tablet computers is relatively concentrated and extensive. In addition, in the two major markets of electric vehicles and industrial/energy storage applications, 3c lithium batteries also occupy a relatively important share. From this point of view, 3c lithium batteries have already penetrated the lives of the public in the fields of communication and transportation. With the development of intelligence and technology, new smart products such as wearable smart devices and drones have been gradually applied. Therefore, the market prospect of 3c lithium batteries is quite broad.

　　Second, the importance of 3c lithium battery

　　Since 2012, smartphones in the Chinese market have begun to replace traditional feature phones. Today, the appearance of smart phones is becoming more and more fashionable and beautiful, the body is becoming thinner and thinner, and the functions are rapidly expanding. When people choose, they will pay more attention to the hardware performance of mobile phones. As mobile phone software increases and energy consumption increases, the durability of mobile phone power has become an important consideration for the public when purchasing mobile phones.

　　With the rise of Chinese companies in the smartphone market, the influence of Huawei, Xiaomi, oppo, ZTE, vivo and other mobile phone brands has become more and more far-reaching. In the production of smartphones, there will be higher requirements for hardware performance. . This is very beneficial to China's lithium battery market.

　　3. The necessity of 3c lithium battery testing

　　Mobile phones, mobile power supplies, and tablet computers will be strictly tested when they leave the factory, especially battery devices. In the testing of lithium batteries, there will be a series of tests, including appearance testing, basic chemical energy testing, and lithium battery performance testing. The necessity of performance testing of 3c lithium battery is mainly explained here.

　　The life detection of 3C lithium battery is very important. The number of cycles of the lithium battery means how many times it can be charged and discharged; according to the use environment of the battery, how much its cycle life can reach at different temperatures; and its waste rate and Discarded standards, etc. are all subject to standard measurement.

　　The safety test of 3C lithium batteries should not be underestimated. When we see reports about the explosion of mobile phone batteries in the news, we will inevitably worry about the performance and safety of mobile phones, so battery safety testing is necessary. When testing, professional module testing equipment is needed to test the stability and impedance of lithium batteries one by one.

　　Why is the performance of the shrapnel microneedle module stronger than that of the pogo pin probe module?

　　The shrapnel micro-needle module and the pogo pin probe module are both test pin modules used in the testing of 3C lithium batteries, LCD, OLED screens, and mobile phone cameras. In the test, it can play the role of transmitting signals and conducting current. With the development of science and technology, the size of digital products is getting thinner and thinner, and the internal space parts are dense, so the precision and space requirements for the test needle module are also getting higher and higher. As a test connection electronic component used to test PCBA in electronic testing, what is the difference between the shrapnel microneedle module and the probe module?

　　From the analysis of the shape, structure, service life and performance of the shrapnel microneedle module and the probe module, we can gradually understand why the performance of the shrapnel microneedle module is stronger than that of the probe module.

　　The shrapnel microneedle module is an integrally formed shrapnel structure, made of nickel alloy/beryllium copper material, made by laser equipment and special process, and then hardened and gold-plated in the later stage. The shrapnel microneedle module has the characteristics of light and thin integration, the overall height and contact shape are easy to make according to customer requirements, different head shapes are used to contact different test points, which play a good connection role and ensure the test stability.

　　The composition structure of the probe module is relatively complex, consisting of a spring, a needle, a needle tube, and a needle tail, and the surface is covered with gold plating. However, the thickness of the gold plating in production is difficult to control, the cost is relatively high, and the production process is also more complicated. During the test, the probe module may be stuck or broken, which is not conducive to the stability of the connection.
