A method includes attaching multiple layers to a back side of at least a portion of a fluid dispensing subassembly having at least one inlet port to form a fluid dispensing assembly, aligning a laser to a region of the fluid dispensing assembly, the region corresponding to the inlet port, and forming at least one hole in the region using a laser, the hole completing a path through the layers to the inlet port. A fluid dispensing assembly has a fluid dispensing subassembly having at least one inlet port, a fluid manifold having at least one outlet, at least two layers between the fluid dispensing subassembly and the manifold, and a fluid path in the at least two layers between the outlet and the inlet port, the fluid path having smooth walls and substantially uniform width.
