Printbars and methods of forming printbars
Abstract:
A method of forming a printbar module may include providing a printed circuit board (PCB) having a recess extending partially through the PCB and a dam surrounding the recess. An adhesive material may be applied to the recess and a printhead die sliver may be positioned in the recess. The printhead die sliver may be bonded with the PCB and the printhead die sliver and the PCB may be encapsulated with a molding compound. In response to encapsulating, a slot, extending through the PCB and the adhesive material may be formed, wherein the slot is in fluidic communication with fluid feed holes of the printhead die sliver to provide direct fluidic communication without fan-out.
