Abstract
This specification discloses a manufacturing method for an ID circuit of inkjet chips. The method includes the steps of: forming an ID circuit at the predetermined position for an ink feed slot near a print head chip, not cutting or cutting the ID circuit during the ink feed slot processing according to the ID characters to form an ID circuit that is able to recognize the type of the inkjet chip. This method is particularly applicable to monochromic and color print head chips using a shared chip module. The ID circuit is manufactured during the process of making the ink feed slot. Therefore, the manufacturing process is simple without any additional requirement.
