Abstract:
A method of providing alignment of a tape automated bonding (TAB) strip with a pagewidth ink jet printhead to facilitate accurate registration of the strip with the printhead, the printhead incorporating a monolithic printhead chip which is manufactured using deposition and etching techniques to define a series of bond pads for connecting the chip to the tape automated bonding strip, the bond pads being arranged in a line along one edge of said printhead chip, the method comprising the step of:forming an abutment rail on a substrate of the chip adjacent to said bond pads, the step of forming the abutment rail further including the steps of: forming the abutment rail along a length of the chip; spacing the abutment rail from said one end of the chip so that the bond pads are positioned between the abutment rail and said one edge; and forming the abutment rail so that the abutment rail defines an abutment surface against which the tape automated bonding strip can abut so that accurate positioning of the strip relative to the bond pads can be achieved.
