Ink jet printing head manufacturing method has piezoelectric rods fixed to base plate in correspondence to ink jet rows before edge machining and separation into individual piezoelectric elements

摘要

The manufacturing method has piezoelectric element rods fixed to the surface of a base plate (6), in correspondence to the ink jet rows, before cutting 2 rebated edges (15a,15b) along the top edges of each piezoelectric rod and dividing the piezoelectric rods into individual piezoelectric elements (4) for the individually controlled ink jets along each ink jet row..
