DROPLET DEPOSITION APPARATUS

摘要

A component for a drop-on-demand piezoelectric printhead is formed from a block of piezoelectric material (100) and a substrate (86). The block of piezoelectric material has grooves formed in its lower surface (681) and is attached to the substrate using an adhesive (670) that is applied in sufficient quantity such that adhesive enters the grooves cut into the piezoelectric material. Upper grooves (7) are sawn into the piezoelectric material through to the glue-filled lower channels (681) in order to form ejection channels, the walls (13) of which are separated from one another by means of a glue fillet (680).
