Abstract
In a method of making an ink jet printhead, corrugations are formed by laser ablation in the bonding surface of a polymer nozzle plate. Adhesive is applied to the micro-cavities thus formed and the nozzle plate is pressed against the end surface of the printhead until the surface lands in the nozzle plate abut on the surface of the printhead.

A method of making multichannel droplet deposition apparatus, comprising the steps of forming a body with a plurality of parallel channels terminating in a common channel termination plane;
- providing a nozzle plate for mounting on the body at the termination plane to provide, through apertures in the nozzle plate, respective droplet ejection nozzles for the channels;
- said nozzle plate having a bonding surface provided with surface micro-cavities and bonding surface lands and with adhesive flow channel means disposed so as in the assembled apparatus to be spaced in the termination plane from the channels;
- applying adhesive to the bonding surface of the nozzle plate so as to fill said cavities;
- placing the nozzle plate in register with the body;
- bringing the lands of the nozzle plate bonding surface substantially into contact with the termination plane of the body;
- and promoting hardening of the adhesive.
A method of making multichannel droplet deposition apparatus, comprising the steps of forming a body with a plurality of parallel channels terminating in a common channel termination plane;
- providing a first bonding surface at said channel termination plane;
- providing a nozzle plate for mounting on the body at the termination plane to provide, through apertures in the nozzle plate, respective droplet ejection nozzles for the channels;
- providing a second bonding surface on said nozzle plate;
- forming in one of said first and second bonding surfaces a regular array of surface micro-cavities and bonding surface lands, forming in said one bonding surface adhesive flow channel means disposed so as in the assembled apparatus to be spaced in the termination plane from the channels;
- applying adhesive so as to fill said micro-cavities;
- placing the nozzle plate in register with the body;
- bringing the lands of said one bonding surface substantially into contact with the other bonding surface;
- and promoting hardening of the adhesive.
