Patent ID: 7784909

Claim:
An ink jetting structure, comprising: a flexible cable having a plurality of conductors, said plurality of conductors having a first end and a second end, said first end being for coupling to corresponding contacts on a printer; a substrate having a first surface and a second surface spaced from said first surface, said substrate having a second fluid passage extending from said first surface to said second surface, said second fluid passage being in fluid communication with said first fluid passage; an ink jet heater chip mounted to said second surface of said substrate, said ink jet heater chip being in fluid communication with said second fluid passage of said substrate, and said ink jet heater chip including a first set of electrical contacts; and a printhead circuit member having a third surface and a fourth surface spaced from said third surface with embedded conductors being located between said third surface and said fourth surface, and having an opening configured to receive said ink jet heater chip with said first set of electrical contacts of said ink jet heater chip being exposed through said opening, said third surface being mounted to said second surface of said substrate, said fourth surface having a second set of electrical contacts attached by wire bonds to said first set of electrical contacts of said ink jet heater chip, and said third surface having a third set of electrical contacts electrically coupled by said embedded conductors in said printhead circuit member to said second set of electrical contacts, and said third set of electrical contacts being electrically connected to said second end of said plurality of conductors of said flexible cable.
