Abstract
An assembly, in an example, may include at least one die, a substrate comprising at least one electrical trace, a lid coupled to a first side of the substrate to contain an amount of fluid between the substrate and lid, and an adhesive film coupled to a second side of the substrate to protect the at least one electrical trace wherein the lid further comprises a main chamber for each of at least two distinct fluids and an overflow chamber fluidically coupled to each of the main chambers via an overflow channel.

A fluidic cartridge, comprising:
- a substrate, the substrate comprising at least one die coupled to a first side of the substrate, wherein the at least one die is electrically coupled to a number of electrical interface pads via at least one electrical trace defined on a second side of the substrate;
- and
- a lid coupled to the second side of the substrate forming at least one fluid chamber between the lid and the substrate.
A fluid delivery cartridge, comprising:
- at least one die to fluidically dispense at least two different colors of printing fluid;
- a substrate, wherein the at least one die is coupled to a first surface of the substrate;
- at least one electrical trace defined on the first surface of the substrate, the at least one electrical trace electrically coupling the at least one die to at least one electrical interface pad;
- and
- a lid coupled to a second surface of the substrate, the lid forming at least two main chambers to maintain the at least two different colors of printing fluid.
