Method for manufacturing a face shooter ink jet printing head

A method for manufacturing an ink jet printing head comprising the steps of:

• parallel processing a single glass plate to form a plurality of different module plates including forming a plurality of bores in each of said different module plates in said single glass plate and forming at least one vertical nozzle channel in at least some of said different module plates in said single glass plate, forming ink chambers in at least some of said different module plates in said single glass plate, and applying electrical interconnects to at least some of said different module plates in said single glass plate so that each of said different nozzle plates has at least one of a vertical nozzle channel and an electrical interconnect;
• precision grinding one side of said single glass plate to produce diaphragms having a predetermined thickness in at least some of said different module plates;
• producing horizontal nozzle channels and further channels in at least some of said different module plates in said single glass plate, and producing plate separation lines, by etching said single glass plate, and giving said horizontal channels and said further channels a predetermined depth by precision grinding from a side of said single glass plate opposite said one side;
• separating said different module plates along said plate separating lines and joining said different module plates to form a plurality of modules, each module having two exterior module plates, at least one of said two exterior module plates being among said module plates having said electrical interconnects applied thereto and each module further having, disposed between said two exterior module plates, at least one of said module plates having said at least one vertical channel formed therein;
• applying piezoelectric elements to said at least one of said exterior module plates of each module and contacting said piezoelectric elements to said electrical interconnects on said at least one of said exterior module plates of each module;
• and
• assembling said modules to form a printing head.

• applying a layer of piezoelectric material on said single glass plate and selectively removing piezoelectric material in said layer of piezoelectric material to form a plurality of piezoelectric elements respectively on said at least some of said different module plates in said single glass plate having said electrical interconnects applied thereto;
• respectively contacting said piezoelectric elements to said electrical interconnects on said single glass plate;
• separating said different module plates to obtain separated module plates;
• joining said separated module plates in respective combinations to form a plurality of modules. each module having two exterior plates and at least one interior plate, said exterior plates respectively comprising two of said module plates having said piezoelectric elements thereon and said at least one interior plate comprising at least one of said module plates having at least one vertical channel therein;
• and
• assembling said modules to form a printing head.
