After 3C lithium-ion batteries pass the 3C certification, battery manufacturers can start production. The completed 3C lithium-ion battery will also undergo performance and safety tests. How to ensure that the test is carried out safely and effectively is the primary issue of demand processing. The high-current shrapnel microneedle module provides a processing method for 3C lithium-ion battery testing.

　　The high-current shrapnel micro-needle module is the transmission preface of connection and conduction, which can effectively ensure the continuity of the connection during the 3C lithium-ion battery test process. It can transmit large currents, and has a strong habit in small pitches, and has a long service life.

　　The rated current of the high-current shrapnel microneedle module can reach 50A, and the current transmission is very stable in the range of 1-50a. The reason is that the current flows in the same data body, the resistance is constant, and there is no current attenuation, so it has a better connection function, so that the 3C lithium-ion battery test can proceed smoothly.

　　In the small pitch category, the minimum pitch value of the high-current shrapnel microneedle module can reach 0.15mm, breaking through the limitation of the traditional probe module. Between 0.15mm~0.4mm, it has strong habitability, its expressive power and service life are much higher than the probe module, and the connection is stable and reliable.

　　The average service life of the high-current shrapnel microcrystalline module exceeds 20w times, and can reach 50w times under good operation, environment and maintenance conditions. Maintain long-term stability in 3C lithium ion battery test. The self-cleaning function of the shrapnel head makes the test free of impurities and the yield reaches 99.8%.

　　As far as 3C lithium-ion battery manufacturers are concerned, the characteristics of high-current lamellar micro-modules have solved the problems of 3C lithium-ion battery testing and provided a stable guarantee for testing. It can assist in the orderly production of 3C lithium-ion batteries, both in terms of performance and cost performance.
