Abstract:
A fluid ejecting device including a die including a perimeter defined by a first edge, a second edge opposing the first edge, a third edge, and a fourth edge opposing the third edge, wherein the third and fourth edges are disposed at an angle to the first and second edges to form angular corners, an active area including circuitry for controlling the fluid ejecting device to eject fluid, an inactive area positioned between the perimeter and the active area, and a termination ring encircling the active area, the termination ring including sides extending parallel to the first, second, third, and fourth edges and corners coupling adjacent sides, the corners having a corner radius greater than a first distance between the first edge and one of the sides of the termination ring, and a nozzle to eject fluid.
