Abstract:
A method of fabricating a print head assembly for use in an ink jet printer, said method comprising the steps of:providing a print head body portion formed from a piezoelectric material and having a front end surface, and a spaced interior series of parallel ink receiving chambers opening outwardly through said front end surface;providing an orifice plate having a rear side surface;forming spaced apart adhesive receiving openings in said orifice plate and said front end surface of said body portion;applying a layer of adhesive material between said front end surface of said body portion and said rear side surface of said orifice plate;forcing said orifice plate and said body portion toward one another in a manner reducing the thickness of said layer of adhesive material and causing portions of said layer of adhesive material to flow into said adhesive openings in both said orifice plate and said body portion, to thereby strengthen the adhesive bond between said orifice plate and body portion by increasing the total contact area between said adhesive material and said orifice plate and body portion; andpermitting the adhesive material to harden.
