Controlling adhesives between substrates and carriers

A print head with a controlled adhesive between a substrate and a carrier, comprising:

• a substrate with a front side surface and a backside surface ;
• at least one ink firing chamber adjacent said front side surface and an ink reservoir adjacent said backside surface;
• an ink feed slot formed through a thickness of said substrate from said backside surface to said front side surface;
• and
• said backside surface comprising a bonding area proximate said ink feed slot and at least one depression formed in said bonding area.

A system with a controlled adhesive between a substrate and a carrier, comprising,

• a substrate with a front side surface and a backside surface;
• at least one ink firing chamber adjacent said front side surface and an ink reservoir adjacent said backside surface;
• an ink feed slot formed through a thickness of said substrate from said backside surface to said front side surface;
• said backside surface being bonded with an adhesive to a substrate carrier at bonding areas formed in said backside surface and in said substrate carrier, said bonding area being located between said ink feed slot and a second ink feed slot formed in said backside surface;
• and
• at least one depression formed in one of said bonding areas being at least partially filled with said adhesive.
