Abstract: A printhead includes a printhead die and an interconnect substrate. The printhead die includes a surface. The interconnect substrate includes electrical circuitry and a surface. The electrical circuitry is in electrical communication with the printhead die through a plurality of electrical connections. An encapsulant structure is positioned to encapsulate the plurality of electrical connections, and includes a barrier portion and a filler portion. The barrier portion includes a first wall and a second wall. The first wall is in contact with the surface of the printhead die and the second wall is in contact with the surface of the interconnect substrate. The filler portion is in contact with the plurality of electrical connections and positioned between the first wall of the barrier portion and the second wall of the barrier portion.

Abstract: A system and method for controlling the stopping point of a tufting machine in relation to a preset stitch pattern. The system includes a controller and an encoder to detect the current location of a tufting machine needle bar in the stitch pattern. Upon receipt of a stop signal, the controller insures that the needle bar is stopped at a preset stop step in the stitch pattern. In a preferred embodiment of the invention, the controller first slows the main drive shaft of the tufting machine to a jogging speed prior to stopping the tufting machine, and stops the machine at the home position of the carpet pattern. Introducing a delay between receipt of the stop signal and deceleration of the main drive shaft minimizes the jogging time of the machine. The method is directed to stopping the tufting machine at a predetermined stop step and at a position relative to degrees of mainshaft rotation.
