Controlling adhesives between substrates and carriers

摘要

Controlling adhesives between substrates and carriers includes forming a depression into a bonding area of a backside surface of a substrate of a print head where the bonding area being formed proximate an ink feed slot formed through the thickness of the substrate from the backside surface to a front side surface; placing an adhesive between the bonding area and a substrate carrier, and moving the substrate and the substrate carrier together such that the adhesive flows into the depression.

1. An ink cartridge comprising:
an ink reservoir to store ink; and an integrated print head in fluid communication with the ink reservoir, the integrated print head comprising:
a nozzle layer comprising a number of nozzles formed therein;a substrate having a frontside surface and a backside surface;an ink feed slot formed through a thickness of the substrate from the backside surface to the frontside surface;at least one depression comprising at least one retaining lip; wherein the at least one depression is formed in the backside of the substrate and are removed from the ink feed slot; anda number of ink chambers formed between the nozzle layer and the substrate.
