Abstract
A method of forming a fluid flow structure in which a first fluidic die is molded into a molding material to form a molded die, and a second layer of molding material is molded onto the molded die, the second layer of molding material comprising a first fluid channel to deliver fluid to the first fluidic die.
Claims15
A method of forming a fluid flow structure, the method comprising:
- molding a first fluidic die into a molding material to form a molded die;
- and
- molding a second layer of molding material onto the molded die, the second layer of molding material comprising a first fluid channel to deliver fluid to the first fluidic die.
A fluid flow structure comprising:
- a molded fluidic die comprising a first fluidic die molded into a first layer of molding material;
- and
- a second layer of molding material coupled to the molded fluidic die and comprising a first fluid channel to deliver fluid to the first fluidic die.
A fluid ejection device comprising:
- a molded fluid ejection die comprising a first fluid ejection die molded into a first layer of molding material, the first layer of molding material comprising a region of molding material adjacent the first fluid ejection die that is substantially coplanar with an upper surface of the first fluid ejection die;
- and
- a second layer of molding material coupled to the molded fluid ejection die and comprising a first fluid channel to deliver fluid to the first fluid ejection die, wherein a first length of the channel is closer to a second length of a fluid feed hole region of the fluid ejection die than to a third length of the fluid ejection die.
