[0001] The present invention claims the priority of the prior Chinese application with the application date of August 22, 2023, the invention name of “A regeneration chip and its manufacturing method” and the application number of 202311063126.9, the prior Chinese application with the application date of August 24, 2023, the invention name of “A regeneration chip for ink cartridge and its manufacturing method” and the application number of 202311078271.4, and the prior Chinese application with the application date of August 25, 2023, the invention name of “A regeneration chip for ink cartridge and its manufacturing method” and the application number of 202311089094.X. All contents of the prior Chinese applications are cross-referenced in this application. Technical Field

[0002] The present invention relates to the technical field of printers, and in particular to a regeneration chip for an ink cartridge and a manufacturing method thereof. Background Art

[0003] At present, in order to enable the imaging device (printer) to timely identify the relevant information of the ink cartridge to avoid incorrect installation of the ink cartridge, and to record the consumption of the printing material in real time to avoid damage to the imaging device, a storage chip is often provided on the ink cartridge. The storage chip stores the relevant information of the ink cartridge, such as the printing material capacity, ink cartridge identification information, production date, etc., and its cost is relatively high.

[0004] However, with the continuous development of imaging technology, the size of imaging devices is getting smaller and smaller. Correspondingly, the size of ink cartridges as storage containers for printing materials is also limited. Therefore, users need to constantly replace ink cartridges. However, most old ink cartridges are discarded, and these discarded ink cartridges include plastics, chips, etc. Most of them cannot be naturally degraded, especially chips, whose circuits and metals will cause great pollution to the environment. Moreover, due to their high cost, discarding old ink cartridges means that users must spend a high price to buy the chips in new ink cartridges, which will undoubtedly cause users' printing costs to be too high.

[0005] Therefore, the prior art has proposed to recycle the chips on the ink cartridges for reuse, thereby reducing pollution to the environment and reducing the printing costs of users. At present, the number of nine-terminal chips disclosed in Chinese patent CN101712239B is far greater than the five-terminal chips disclosed in patent US11535038B1.
