Abstract

The invention relates to a lithium battery control module thermal compression welding method and a lithium battery control module obtained after welding. The lithium battery control module comprises a flexible panel and a hard panel. The flexible panel is provided with a flexible panel thermal compression welding disc. The hard panel is provided with a hard panel thermal compression welding disc. The flexible panel thermal compression welding disc and the hard panel thermal compression welding disc are connected through thermal compression welding. The thermal compression welding method comprises the following steps that 1, holes are formed in the flexible panel thermal compression welding disc, and the hard panel thermal compression welding disc and the flexible panel thermal compression welding disc are stacked by printing tin to the hard panel thermal compression welding disc and the flexible panel thermal compression welding disc; and 2, as for a thermal compression welding head with grooves in the end, the grooves in the end of the thermal compression welding head are aligned to the holes in the flexible panel thermal compression welding disc for thermal compression welding, and the printed tin on the hard panel thermal compression welding disc is turned upwards via the holes in the flexible panel after melting so as to form welding rivets. By means of the lithium battery control module thermal compression welding method and the lithium battery control module obtained after welding, the problems of false welding and unstable welding of an existing traditional welding technique are solved.

Description

technical field [0001] The invention relates to a lithium battery control module hot-press welding method and a lithium battery control module after welding. Background technique [0002] In the field of lithium battery control systems, due to the ultra-thin development characteristics of terminal products, the volume of lithium batteries is also required to be ultra-thin. Therefore, the lithium battery control system has emerged in the past two years with the characteristics of a combination of soft and hard PCBA technology. The joint process between the soft board and the hard board is completed by the PCB manufacturer at one time. In addition, the soft board and the hard board need to be post-soldered. In addition, due to the ultra-micro size of the lithium battery used in wearable products, the lithium battery control module and the battery cell are welded with fine wires; the lithium battery control module with the above two types of characteristics usually adopts spot ...
