Abstract

A fluid manifold may include a number of blades and a number of end pieces securing the blades in place wherein the fluid manifold interfaces between a printhead die and a number of fluid source slots. A method of manufacturing a fluid manifold may include arranging a number of metal blades to form a relatively larger pitch between blades on a bottom side of the arranged blades than on a top side the arranged blades and mounting the arranged blades to a mounting structure formed to receive each blade as arranged.

First claim

What is claimed is:

1. A fluid manifold, comprising:
a number of blades, the number of blades in the form of a plurality of hoops; and
a mounting structure securing the blades in place;
wherein the fluid manifold is to interface between a printhead die and a number of fluid source slots.

2. The fluid manifold of claim 1 , wherein the number of blades are made of steel.

3. The fluid manifold of claim 1 , wherein an upper portion of the blades interface with a printhead die comprising a number of overmolded printhead dies.

4. The fluid manifold of claim 3 , wherein each of the blades comprise beveled edges on each of an upper portion of the blades.

5. The fluid manifold of claim 1 , wherein a lower portion of the blades interfaces with a number of fluid feed slots having a pitch larger than a nozzle pitch on the printhead die.

6. The fluid manifold of claim 1 , wherein the number of blades form a number of fluid feed slots through which distinct colors of ejection fluid may be passed to the printhead die.

7. A method of manufacturing a fluid manifold, comprising:
arranging a number of metal blades between a number of sliding blades to form a relatively larger pitch between blades on a bottom side of the arranged blades than on a top side the arranged blades; and
mounting the arranged blades to a mounting structure formed to receive each blade as arranged.

8. The method of claim 7 , further comprising forming a beveled edge on the top side of each blade to interface with a bottom surface of a printhead die.

9. The method of claim 7 , further comprising applying a layer of glue to each of the blades where each of the blades contacts the mounting structure prior to coupling the end piece to each end of the blades.

10. The method of claim 7 , wherein the blades are bent along an axis formed from the top side to the bottom side.

11. The method of claim 7 , wherein the blades are formed into a flat surface along an axis formed from the top side to the bottom side.

12. The fluid manifold of claim 7 , wherein the plurality of hoops are nested within each other.

13. The method of claim 7 , wherein the sliding blades are pushed against each other and the blades when the number of metal blades have been inserted between the sliding blades.

14. The method of claim 7 , wherein the metal blades are formed of sheet metal and wherein the sheet metal is cut above and below the sliding blades.

15. The method of claim 13 , wherein a number of end pieces are formed at ends of the metal blades.

16. A media wide array, comprising:
a number of printhead dies;
a number of fluid feed slots; and
a number of fluid feed manifolds interposed between each of the printhead dies and fluid feed slots, each manifold comprising blades forming fluid channels from the fluid feed slots to the printhead dies; wherein the blades are formed of steel and the pitch of the fluid channels at a top portion of the manifold is between 590 μm to 3600 μm.

17. The media wide array of claim 16 , wherein each printhead die comprises a number of silicon substrates, each silicone substrate comprising a column of nozzles with each silicon substrate being overmolded with an epoxy mold compound.

18. The media wide array of claim 16 , wherein the pitch of the fluid channels at a top portion of the manifold is 600 μm or less.

19. The media wide array of claim 16 , wherein each of the fluid feed manifolds further comprise end pieces to hold and maintain the blades in a predetermined arrangement.

20. The media wide array of claim 16 , wherein a thickness of any of the blades is consistent along an entire length of the blades.
