A method for film coated passivation of individual grooves or channels in an array of closely spaced grooves or channels of a workpiece, for example, ink channels in a printhead employed in an ink jet printer device; includes the steps of placing the workpiece on a rotation plate having a rotational center, securing the workpiece to the rotation plate with the grooves directed ra- dially outward from the rotational center of the rotation plate, placing resin upon the workpiece in the vicinity of the grooves, and spinning the rotation plate to cause the resin to migrate along the surfaces of the grooves and thereby coating them.
