The present invention relates to an ink cartridge for an inkjet printer. A head chip of a print head is formed to be surface-mounted in a BGA method with respect to a FPCB substrate. Thereby, each contact point terminal formed in the FPCB substrate, and the head chip can be formed in a relatively wider area. As highly integrated technology is not required, the FPCB substrate and the head chip are easily manufactured, and manufacturing costs are reduced. As precision of a relatively low degree is maintained in a step of mounting a head chip on a FPCB substrate to contact each contact point terminal, a print head is more conveniently and quickly manufactured. As the contact point terminal formed in the FPCB substrate is arranged to have the optimal space efficiency, highly precise fine manufacturing technology is not required. Therefore, manufacture is easily performed and a mutual bonding step between a head chip and a FPCB substrate is easily performed. |
