Abstract
An ink jet module that can be accurately positioned on a carrier includes a channel die and a heater die. The channel die is rectangular and has a top surface, a bottom surface, a first pair of sides, and a second pair of sides. The bottom surface has a number of spaced parallel channels disposed within it. The channels are parallel to the first pair of sides and extend through one of the second pair of sides. The top surface of the heater die is attached to and aligned with the bottom surface of the channel die. At least one pair of alignment features is disposed within and adjacent a side of the bottom surface of the channel die. The alignment features are recessed areas disposed on opposite sides from each other. The alignment features are dimensioned to receive a retainer that secures the ink jet module to a carrier.
