Abstract
An inkjet printhead includes: a rigid elongate carrier having an ink supply channel and a lower surface having a plurality of printhead chips mounted thereon; a rigid PCB attached to the lower surface of the carrier, the PCB extending a length of the carrier and projecting laterally beyond a sidewall of the carrier; a lead retainer attached to the sidewall of the carrier; and a plurality of leads extending upwardly from contact pads positioned along a longitudinal edge portion of the PCB, each lead being secured to the sidewall of the carrier via the lead retainer. The PCB supplies power and data to the printhead chips via electrical connections between the PCB and the printhead chips.
