the opposite side of the ink for acoustic attenuation the ink then enters the body chamber 74 from which it is forced out the aperture 78 through the body outlet 76 by activation of the transducer not shown the polymer compliant film may provide the adhesive to attach the two sets of plates together to form the jet stack as discussed above several different materials may be used for the compliant film if the compliant film is to act as the adhesive between the two sets of plates the compliant film may consist of double sided tape or may have multiple layers a core layer provides the characteristic compliance to attenuate the acoustic energy that causes the pressure differentials in the ink supply one example may be a thin thermoset polyimide material in addition to the materials mentioned above the outer layers surround the core and may consist of the adhesive layers thermoset and thermoplastic adhesives can be use the thermoset adhesives may be one of several materials including acrylic silicone epoxy and bismaleimide thermoplastic adhesives can include thermoplastic polyimide polyetherether ketone and others the film may be cut by a laser or other means to form any ports for ink and air flow needed in the jet stack configuration these films are generally available in a range of thicknesses from less than.
