ABSTRACT:
An apparatus and method allows for mounting and aligning of the charge plate/catcher assembly and the droplet generator and has six degrees of freedom of adjustment, including three degrees of freedom of translation and three degrees of freedom of rotation. A first degree of freedom of translation comprises a height adjustment of the resonator relative to the charge plate; a second degree of freedom of translation comprises an alignment adjustment for aligning the plurality of jets with respect to the plurality of charge leads; and a third degree of freedom of translation comprises a reciprocal adjustment for moving the plurality of jets relative to the charge plate. Additionally, a first degree of freedom of rotation comprises a first parallel adjustment for aligning the plurality of jets parallel to the charge plate face; a second degree of freedom of rotation comprises a second parallel adjustment for aligning the array of orifices parallel to the charge plate face; and a third degree of freedom of rotation comprises a third parallel adjustment for aligning the orifice plate parallel to the top of the charge leads. The present invention also provides for a strain relief to insure an electrical contact to control leads associated with charge leads.
